Power fluctuation suppression system for large scale PV

The large scale photovoltaic (PV) generation station is expected to spread in the future. However, output power of renewable energy sources such as PV is affected by weather conditions and their output tends to be unstable. As a result, the penetration of PV power station makes it difficult to maintain frequency of power system in allowable range. The authors have developed a suppression system to stabilize output power fluctuation of a large scale PV generation station. To reduce short term fluctuation, storage batteries applying SCiBTM are used. In this paper, verification test results are explained and simulation results to improve control performance are also shown.
