Abstract

This paper presents and verifies a method for centralized voltage control of load ratio control transformers and step voltage regulators for bank fault restoration. In conventional methods, voltage control in distribution systems primarily serves to alleviate voltage violations. Conventional methods remain imperfect, however, so it is necessary to evaluate how to minimize the number of violations during bank fault restoration. Thus, the proposed method adjusts the tap position of voltage regulators to minimize the number of affected customers in consideration of the power factor control of photovoltaic generation systems. We perform numerical simulations of bank fault restoration to verify the effectiveness of the proposed method, and visually compare the results with those of the conventional method.
