Energy Storage System Survey and Battery Case Testing

Energy storage and renewables are important parts of smart grid systems of the future. This paper surveys applications of energy storage systems. It reviews various types of battery systems, flywheels, compressed air energy storage systems and thermal energy storage systems. Then the paper surveys all possible uses of energy storage systems such as volt-var control, frequency regulation, energy arbitrage, etc. Thereafter, the paper presents a proposed testing of large scale battery system at Ryerson University using a 1.2 MWh of battery storage system with a 370 kW converter system connecting a 13.8 kV substation. Detailed system architecture is presented that includes details of the battery system, power electronics, etc. The proposed tests to be completed are outlined explaining potential outcomes in those tests.
