Public Service Company of New Mexico (PNM) deployed a photovoltaic (PV) plus battery storage system to simultaneously mitigate voltage fluctuations through battery smoothing and manage peak demand by using the energy stored in the batteries. PNM is also part of a demonstration of a commercial building microgrid designed and built by the Japanese government's New Energy and Industrial Development Organization (NEDO).
The building with the microgrid, the Aperture Center, is located in the Albuquerque, New Mexico area about 1.7 miles (~2 kilometers) from the PNM PV plus storage system, or about 2.5 circuit miles. The NEDO building microgrid includes a 240 kW gas engine, 80 kW fuel cell, 50 kW photovoltaic array, as well as 50 kW of battery storage, thermal storage, and a building energy management system.
This case study covers a test of the coordinated control of PV smoothing for the PNM system, using the PNM batteries and the NEDO gas-engine generator (GE) and fuel cell.
