Mitigation of voltage variations during cloud transients by using energy storage systems

摘要

The clouds passing over the photovoltaic generators may cause quick variations on active power generation and grid voltage. In this context, the present paper aims to analyse the effectiveness of battery systems applied to solve the mentioned impacts. In order to do that, the IEEE 13 bus was the simulated distribution system. Real measurement data referring to irradiation on a tipical clear and cloudy day was used, jointly with an artificial neural network based control method. The control quick response along with the battery system were able to substantially reduce the explained problem.
