The EPRI team will demonstrate and evaluate the impacts of a near-Zero Net Energy (ZNE) community on the local distribution system and develop mitigation strategies using building energy management systems and energy storage. The team will develop ZNE packages including photolvatics (PV), home energy management systems (HEMS), storage and demand response (DR) for inclusion in a Meritage 60 home community in California. Modeling approaches will be used to predict the impacts on distribution systems and mitigation strategies will be developed. The project will demonstrate how HEMS, DR and storage can mitigate possible grid issues. The project will also integrate building energy models and distribution models to predict building requirements for desired load shapes. The project objectives include demonstrating and evaluating:
-
Cost effective energy efficiency (EE) packages to achieve ZNE
-
ZNE homes with PV, storage, HEMS and DR can provide grid benefits
-
HEMS and DR can manage end-use loads to enable greater PV penetration
-
Various locations for energy storage to address distribution issues
-
Measured impacts that ZNE communties have on distribution feeders
-
Identify requirements for ZNE communities to include in IOU ZNE programs and CA Title 24
Integrate ZNE building modeling approaches with distribution models
