Abstract

In this paper, an Energy Storage System (ESS) based control method is proposed to reduce the PV output power fluctuations, which in turn will reduce the frequency deviations of the power system introduced by large penetration of PV power. The ESS control model introduced here will maintain the energy storage ratio of the ESS near 50%. This will increase the life time of the ESS as well as will decrease the maintenance cost of the ESS. A local search algorithm is also provided with this ESS control model to search the optimal capacity of the ESS required for smoothing the PV output power fluctuations and to find the minimum capital cost. A cost comparison is shown to realize the performance of the search algorithm.
