A STUDY ON THE OPTIMAL VOLTAGE REGULATION METHODS IN POWER DISTRIBUTION SYSTEMS INTERCONNECTED WITH DISPERSED ENERGY STORAGE AND GENERATION SYSTEMS

摘要

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, optimal sending voltages should be decided by the effective operation of voltage regulators at distribution substations. In this paper, optimal voltage regulation methods are presented based on statistical analysis considering the customer voltage conditions and operation characteristics of DSG systems. Optimal operation methods of multiple voltage regulators are also suggested. In addition, the introduction impacts of DSG systems such as optimal location sites and introduction capacity are evaluated.
