Abstract

Renewable energy resource policies are being promoted to solve global resource depletion and environmental problems. Accordingly, as the connection between renewable energy resources and the distribution system has increased, various problems such as degradation in the quality of the power produced and voltage fluctuations have occurred. In this study, to solve the voltage problem, we propose a decentralized real-time volt/var control of the distributed generations (DGs) in a distribution system. The proposed control scheme aims to maintain the voltage for a point of common coupling (PCC) within a specified range, and the proposed control is applied in two stages. The proposed control scheme compensates for the disadvantages of a conventional control scheme and shows a new control structure. The proposed control scheme was applied to the test distribution system using MATLAB and was verified to be more effective than the conventional control scheme.
