CSI RD&D Final Project Webinar:

Advanced Distribution Analytics Services Enabling High PV Penetration

Principal Investigator: SCE

Date/Time: September 23, 2016 at 10:00 AM PDT

Webinar Registration Link:  https://attendee.gotowebinar.com/register/622290973251393538

Southern California Edison, Pacific Northwest National Lab, and QADO Energy teams have worked collaboratively for over two years as part of a research project entitled, “Advanced Distribution Analytics Services Enabling High PV Penetration”, which is funded in part by the CSI RD&D program. The project goal was to develop a framework for achieving high PV penetration levels on California feeders, specifically representative feeders in SCE's service territory, focusing on improving the standardization and transparency of the interconnection process and increasing understanding of cost effective paths to higher PV penetrations.

During this webinar, the project team will focus on discussion of the following topics and key lessons learned:

  • Overview of detailed feeder model development, which includes behind the meter loads, and validation process using the GridLab-D simulation environment
  • Methodology to determine feeder native limits which leverages PV adoption models and Monte Carlo simulation
  • Potential upgrade paths to enable 50%, 75% and 100% PV penetration levels using traditional and non-traditional mitigation strategies such as advanced inverter controls and storage deployment
  • Demonstration of the unique modelling, analysis, and methodology developed by the CSI project using QADO Energy’s GridUnity software

CSI RD&D Final Project Webinar:

Grid Integration of Zero Net Energy (ZNE) Communities

Principal Investigator: EPRI

Date/Time: September 16, 2016 at 10:00 AM PDT

Webinar Registration Link:  https://attendee.gotowebinar.com/register/8575034387552180993

This project was designed to support construction and measure actual performance of ZNE homes and their impact to the distribution grid. The team worked with a national builder to develop California's first ZNE neighborhood with all homes located on specific transformers. The homes were not "test homes" but sold and occupied by real customers, many of them first-time homebuyers. To provide balancing, the heating loads were electrified, which also is aligned with California's long-term decarbonization goals. The PV sizing was designed to meet California's definition of ZNE, and PV orientation varied by a lot. All homes on one transformer were fitted with customer-side energy storage. The end devices were "smart" loads, capable of providing load balancing. The results confirmed that the load shapes of ZNE homes were substantially different, much more volatile, and does not show the standard summertime peak. The peaks are driven by coincidence of water heating and HVAC systems. Energy storage can provide some load shape balancing, but only if controlled for grid load, and not driven by customer economics. This webinar will discuss the experiences in developing the community, impact of solar combined with energy efficiency, strategies for DER integration and possible benefits of demand response and energy storage in the future California distribution grid.

CSI RD&D Final Project Webinar:

Comprehensive Grid Integration of Solar Power for SDG&E

Principal Investigator: University of California, San Diego (UCSD)

Date/Time: August 18, 2016 at 10:00 AM PDT

Webinar Registration Link:  https://attendee.gotowebinar.com/register/9096103942467711234

The University of California, San Diego (UCSD) and its partners will present a webinar on their CSI RD&D Solicitation 4 funded project where they demonstrated forecasting and solar power integration tools. This work included refinement of forecasting and development of battery siting strategies to enable higher penetrations of solar power on the distribution grid.

The UCSD team developed operational solar and net load forecasting systems for San Diego Gas & Electric (SDG&E) that are being used today in grid operations. The purpose of the solar forecast system was to provide solar generation inputs into system-wide net load forecasts and operational load flow analysis. A numerical weather prediction atmospheric modeling system for coastal Southern California was implemented and post processing was applied to improve forecast accuracy.

The main thrust of the project was improving distribution feeder power quality under high PV penetration utilizing battery energy storage systems (BESS). UCSD conducted power flow simulations for 14 representative SDG&E feeders with high PV penetration to quantify voltage variations, overvoltage conditions, and load tap changer operations. The results of the case study highlighted that significant increases in PV penetration levels across all of the 14 feeders are feasible without network augmentation. BESS can further increase high PV penetration, but the ideal siting is a practical challenge. A methodology for optimal allocation of BESS sizes to maximize their support for integrating high penetration PV in residential distribution networks and minimize cost was developed and demonstrated. The effectiveness of the proposed method was demonstrated on the IEEE 8500-Node test feeder and a feeder in the SDG&E service area. Finally a way to leverage phasor measurement units for grid disturbance detection, modeling, and actuation using BESS was demonstrated.

High-Fidelity Solar Forecasting Demonstration for Grid Integration

Principal Investigators: UCSD

Date/Time: Dec 1, 2015 at 10 AM PST

Webinar Registration link: https://global.gotowebinar.com/ojoin/6433901512176124930/300000000000030309

The University of California, San Diego (UC San Diego) and its partners developed, improved, and demonstrated solar power grid integration models. At the broad system level, relevance of solar forecasting to resource adequacy was demonstrated at very high penetration levels based on a characterization of meteorological conditions when large aggregate solar ramps are likely occur. This effort included a number of different areas: • Task 2: Demonstrating forecast performance during meteorological conditions with greatest impact on SDG&E operations and recommending monitoring improvements: Variability in solar irradiance across the San Diego Gas & Electric (SDG&E) territory informed the partitioning of solar climate zones that can be leveraged to optimize ground station coverage and solar plant allocations. • Task 3: Day-Ahead Solar forecast models for marine layer clouds: A well-known but often poorly forecast California-wide phenomenon is the burn-off of marine layer clouds. These clouds can cover a large fraction of rooftop PV systems throughout California. The project team developed forecasting tools through a combination of very high resolution numerical weather prediction, statistical modeling, and dense measurement infrastructure installed by SDG&E. • Task 4: Localized Solar Forecasting and Distribution Feeder Modeling: distribution feeder power quality analysis was forced with total sky imager cloud maps and forecasts to identify voltage control needs under high PV penetration. The modeling was conducted on five representative feeders with variations in PV penetration, location / meteorology, and voltage regulation equipment. When realistic PV input profiles are used tap operations were reduced substantially compared to using the same profile for all PV systems on the feeders. • Task 5: Forecast Integration with Utility Models for Resource Adequacy: For these same feeders net load forecast models were also developed and validated. Solar variability was found to significantly influence net load fore

Two CSI RD&D Final Project Webinars:

Quantification of Risk of Unintended Islanding 

Principal Investigators: GE

Date/Time: Jul 22, 2015 at 10 AM PDT

Webinar Registration Link:   https://attendee.gotowebinar.com/register/8169543285948101377

This webinar presents analytical and experimental work performed by GE and PG&E to evaluate the likelihood of unintended islanding of solar photovoltaic (PV) inverters in distribution applications under realistic field conditions.
Most PV inverters used in distribution applications in the United States today are certified to UL 1741, which ensure that an individual inverter can detect islanding and de-energize within 2 seconds when it is coupled to a defined synthetic load. Realistic conditions in actual distribution circuits, however, are never matching the exact conditions of the UL test – the field conditions generally involve inverters of different makes and models and loads of greater variety than the synthetic load used in the UL anti-islanding test. This raises concerns about feasibility of islanding detection in realistic system conditions and poses the question: What is the maximum level of penetration that can be safely allowed on actual distribution circuits?


GE and PG&E undertook a three-year study to answer this question by performing experimental work using actual PV inverters and the flexible load specifically designed to enable streamlined evaluation of different load compositions. The flexible load uses a power electronic inverter to simulation distribution load in real time based on WECC’s composite load model executing on a Real Time Digital Simulator (RTDS). This enables evaluating loads of different compositions to more closely represent load variety found on distribution circuits in PG&E service territory.

 

Methods for Screening Distribution Feeders: Alternatives to the 15% Rule

Principal Investigators: EPRI

Date/Time: Jul 24, 2015 at 10 AM PDT

Webinar Registration Link:   https://attendee.gotowebinar.com/register/3077174972957233922

The Electric Power Research Institute (EPRI), National Renewables Energy Laboratory (NREL), and Sandia National Laboratory (SNL) will be presenting a final webinar on the Methods for Screening Distribution Feeders: Alternatives to the 15% Rule project. The objective of this project was to improve the utility application review and approval process for interconnecting photovoltaics (PV) to the utility distribution system. Working with the three investor-owned utilities, the project team evaluated the impacts of PV on the distribution system through detailed hosting capacity analysis. The results of this analysis led to the identification of additional fast-track initial and supplemental review screens that could be applied alongside the existing California Electric Rule 21 screens. These new screens are derived directly from our technical analysis and will better predict the amount of PV that can be accommodated on a feeder regardless of its loading.

Date/Time: Sept 9, 2014, 1:30 - 3:30 pm PDT

Webinar registration linkhttps://www4.gotomeeting.com/register/312055895

UC Davis West Village is the largest planned zero net energy community in the United States. It is on track to demonstrate, for the first time, that zero net energy is practical on a large scale. Energy efficiency measures have reduced projected energy demand by approximately 50 percent as compared to current building code requirements. Renewable energy will meet the remaining energy needs on an annual basis.

The CSI RD&D research project included a smart grid feasibility study and the execution of four technology demonstration projects at the UC Davis West Village and Aggie Village in Davis, CA.

PVT Demonstrations: The findings from the installation of two solar combined heat and power (PV and solar thermal - PVT) systems will be presented. One system was installed on an existing single family home and another on the multifamily Zero Net Energy (ZNE) apartment building at the West Village campus of UC Davis.

West Village Smart Grid Feasibility Study: This study, performed by the GE Smart Grid Center of Excellence, evaluated the early performance of the West Village ZNE community and made recommendations to integrate smart grid systems, such as HVAC and Demand Response controls into the future phases of development.

Battery Storage Demonstrations: Findings from the installation of two lithium-ion battery storage systems at UC Davis West Village and the retrofit home in Aggie Village will be presented. The first demonstration integrated a 35kWh li-ion battery into a ZNE building at West Village. The second demonstration integrated a 10kWh second life-use lithium-ion battery into a single family home.

Project: BEoptCA(Ex) - Optimization platform for EE/DR/PV in residential retrofit
Principal Investigators: Davis Energy Group and NREL
Date/Time: March 5, 2014, 10 am - noon PST

The National Renewable Energy Laboratory (NREL), Davis Energy Group (DEG), and Energy and Environmental Economics (E3) will be presenting a final webinar on the BEoptCA(Ex) project. This project targeted the development of a software tool, BEopt-CA (Ex) (Building Energy Optimization Tool for California Existing Homes), that facilitates balanced integration of energy efficiency (EE), demand response (DR), and photovoltaics (PV) in the residential retrofit market. The intent of the software tool is to provide utility program managers and contractors in the EE/DR/PV market place with a means of balancing the integration of EE, DR, and PV within the residential retrofit market. NREL's existing BEopt software was enhanced by adding capabilities in the following areas: existing home retrofit analysis, retrofit measures and cost data, utility tariff capabilities, time dependent valuation (TDV), utility cost-effectiveness tests, incentives for PV and whole-house efficiency, and demand response. The new version of BEopt can be launched in a "California Metrics" mode to utilize these specific capabilities. Preliminary work was also done on connecting BEopt to the new California Simulation Engine (CSE) being developed for use in California residential building energy codes (Title-24).

Project: Low Cost Solar Retrofit - Grid Ready Plug and Play PV Kit
Principal Investigator: BIRAenergy
Date/Time: December 10, 2013, 10 am - noon

BIRAenergy, in partnership with GE and SDG&E, demonstrated a low cost "plug and play" roof-mounted photovoltaic (PV) system for asphalt-shingle roofs. The project found that timing the install of PV with re-roofing or deep energy efficiency retrofits resulted in cost efficiencies due to partnering among the various trades and related process efficiencies in a plug and play PV kit. The project team developed an installation best practice guide, cost analysis and business model to help bring the installed cost of PV to under $4.50/W in the single family residential retrofit market, without the benefit of volume installs. The project demonstrated the plug and play PV kit install at six different homes in Southern California, one of which was retrofitted to be ZNE and includes storage. This CSI RD&D webinar will provide a summary of the project along with key results and findings.

E3 webinar - Improving the economics and incentives for integrating high penetration PV

Date: Wednesday, July 10, 2013
Time: 1:00 PM - 2:30 PM PDT (revised time)

E3 will present the findings from a CSI RD&D funded study on improving the economics and incentives for integrating high penetration photovoltaic (PV) systems and intermittent renewables using distributed energy resources (DER). The E3 team proposed and evaluated peak load shifting, solar PV firming, and grid support strategies for integrating renewables and simulated each strategy using one year of data from the University of California, San Diego (UCSD) microgrid. This analysis contribution to existing research by:

  1. Documenting the potential to engage existing DER for renewable integration with limited additional capital expenditure,
  2. Modeling the dispatch, costs and benefits of microgrid operation for both customer and utility grid benefits,
  3. Integrating and optimizing both electric and thermal resources for renewable integration benefits, and
  4. Comparing the costs and benefits of multiple strategies over a full year with validated historical data.

E3 found that UCSD DER dispatch strategies are technically feasible and can be cost-effective, but current tariff designs inhibit their performance, and net cost-savings are small relative to total campus resource costs. For each renewables integration strategy, the team modeled and evaluated the cost-effectiveness of alternative incentive, tariff and resource dispatch cases. The findings suggest alternative incentive mechanisms and engagement strategies beyond direct load participation and dynamic pricing strategies currently under consideration are needed. These strategies are relevant for DER resources across campuses and similar commercial and industrial loads across the state.

SunLink webinar

Date: Tuesday, December 18, 2012
Time: 10:00 AM - 12:00 PM PST

Reducing California PV Balance of System Costs by Automating Array Design, Engineering, and Component Delivery

The SunLink team will present the findings and work products from their 2 year CSI RDD Program funded project.

The project built on SunLink's prior work to support the industry by enabling cost-effective optimized designs for commercial roof mount PV systems. In 2010 system installation and balance of system (BOS) components accounted for 50 percent of the cost of a PV system. In 2012, with declining module costs, this percentage is even greater. Any reduction in BOS costs can have a significant impact on the installed cost of a PV system. SunLink research focused on increasing automation and decreasing the time spent on engineering from system layout to final package. The team analyzed the seismic and wind impacts on the structural integrity of ballasted systems to enable streamlining engineering of such systems.

Additionally, SunLink explored automation of the documentation process from project approval through system installation and initiated a permitting requirements database.

kW Engineering Sol#1 final project webinar

IEP Model

Date: Monday, April 23, 2012
Time: 10:00 AM - 12:00 PM PDT

Devan Johnson of kW Engineering will be presenting the webinar. The IEP team has been funded by the CPUC's California Solar Initiative (CSI) to develop an Integrated Energy Project (IEP) Model to standardize and integrate the data underlying energy efficiency upgrade and the decision to add solar. The IEP Model introduces a common language to project stakeholder software applications - it provides a comprehensive, standardized definition of an EE/DR+PV project, as well as how stakeholders can communicate between each other about that project. This aims to simplify and streamline the process, reduce time and costs for both the consumer and contractors, produce a better ROI for both, and remove a key market barrier for the adoption of both EEM's and solar energy.

Clean Power Research Sol#1 project - webinar on Apr 10

Advanced Modeling and Verification for High Penetration PV

Tom Hoff, president of Clean Power Research, will present several key findings from the company's CSI RD&D Solicitation #1 research project, "Advanced Modeling and Verification for High Penetration PV." The purpose of the grant project was to generate enhanced resolution irradiance data and make available new PV fleet power output simulation methodologies to help utilities and ISOs evaluate the impact of high-penetration PV to their distribution systems. As a result of these new data resources and PV fleet output capabilities, the project team was able to quantify the reduction in output variability that results from geographically dispersed PV systems, allaying some of the concerns associated with variability caused by high-penetration PV. These findings, in combination with high-speed PV fleet output tools, provide planning benefits at both the transmission and distribution levels, enable utilities and ISOs to more easily perform grid integration studies, and hold the promise for cost-effective prediction of short-term output forecasting of PV system performance.
