Abstract

This paper summarizes international experience of significant clustered photovoltaic systems. Based on the operation experience, major system impacts and corresponding solutions have been studied. Among them, voltage raise of power distribution line due to the reverse power flow from the PV system has been one of the main problems. Therefore, this paper proposes the dynamic and steady-state simulations to evaluate the effectiveness of battery-integrated PV system on avoiding the over voltage problem. Furthermore, different types of battery control modes have been compared. In the simulations, the actual product specifications were adopted as the parameters of the component models, and the largest PV cluster system in Taiwan was chosen as the analyzed demonstration site. The simulation results reveal that the developed control algorithms could avoid voltage rise by setting appropriate control parameter values. In addition, these control algorithms could be applicable to other power grids if appropriate settings are made.
