Voltage Regulation Methods Based on an Extended Approach and Neural Networts for Distribution Systems Interconnected with Dispersed Storage and Generation Systems

Abstract

This paper deals with optimal voltage regulation methods in power distribution systems including Dispersed Energy Storage and Generation (DSG) systems. In order to deliver suitable voltages to as many customers as possible, the optimal sending voltage should be decided by the effective operation of voltage regulators at the distribution substations. In this paper, a modified voltage regulation method based on the existing method is presented and an optimal coordination method of multiple voltage regulators is extended. An on-line real time voltage regulation method by using neural networks is also proposed. In addition, the introduction impacts of DSG systems such as optimal location sites and introduction capacity are evaluated. The results from a case study show that the proposed methods can be a practical tool for the voltage regulation in distribution systems.
