Solar+ Storage Integrated Energy Management Demonstration in a Supportive Housing Facility
Innovations and energy savings for multi-tenant, low-income housing using solar+storage technology.
The mixed-use supportive housing building was completed in 2020, and has initiated occupancy in early 2021. UC Riverside is replacing the storage system to meet certification requirements for interconnection. The solar PV system is being procured in 2022, and the full system is expected to be commissioning by end of Q2 2022. The research team has submitted their Smart Inverter Performance Assessment Test Plan and will be drafting their System Impact Assessment and Validation Plans while the replacement battery system is being procured.
The project deploys a 100 kW high-performing solar PV system, a 150 kW/150 kWh li-ion battery energy storage system, a smart inverter, and an advanced energy management platform to demonstrate different use cases and showcase the advanced functions of smart inverters. These components will be integrated to optimize flexibility in demand side energy management through load shifting, solar PV self-consumption, emergency back-up, demand response, and ancillary grid services. The proposed system will be able to autonomously meet demand response and energy management requests while critical loads at the building are maintained, minimizing operational impacts. It will also realize energy and demand charge cost savings to the building owner and tenants.
This project will reduce peak energy demand by integrating PV generation with battery energy storage to shift building and community loads. The reduction of peak energy use will lower consumer's energy bill.
This effort will demonstrate the commercial feasibility to deploy many MWh of dispatchable energy integrated in a PV/BESS configuration with smart inverters to manage energy use through load shifting and emergency back-up.
