【 摘 要 】

As the penetration of Renewable Energy Sources (RESs) increases, the countermeasures are becoming increasingly important because output of the RES is intermittent. Therefore an Energy Storage System (ESS) that can control generation is attracting attention and undergoing various studies in order to stabilize efficiently the output of the RES. The conventional method estimates the capacity of the ESS through error of actual data of the RES's power and reference point using moving average method. However, as the error between reference power and output power of the RES increases, the capacity of the ESS increases. Therefore, in this paper, we propose method for estimating the capacity of the ESS using the improved moving average method.
