UCLA researchers have developed a battery energy storage system capable of both shifting power consumption pattern and shaping power consumption profile with minimal delay.
Energy management systems (EMS) enable optimization of energy generation, transmission, and utilization. Utilization of battery energy storage systems (BESS) has recently been investigated in addition to conventional energy management systems for active controls.
The invention is a battery energy storage control system (BESS) capable of both shifting power consumption pattern and shaping power consumption profile with minimal delay. The hardware of the system consists of local controller hardware and central controller hardware:
The software system consists of a communication control section, an operation control section, and a safety control section:
The integrated control system is capable of:
The software has been developed and integrated into a lab-scale grid-connected battery energy storage system for data acquisition and analysis. Power demand shaping has been demonstrated by smoothing the power fluctuation of solar panels on a building, whereas power demand shifting has been demonstrated on the vehicle charging stations in a parking structure at UCLA.
