Abstract

This paper focuses on the low voltage direct current (LVDC) distribution system that has been developed and implemented in Gochang Power Testing Center located in Joennam Province, South Korea by Korea Electric Power Corporation (KEPCO). Low-voltage distribution can suffer voltage regulation issues because of voltage drop in distribution lines. This paper presents the implementation of the hierarchical control algorithm to coordinate multiple AC/DC converters and multiple distributed energy resources (DERs) for LVDC distribution system using multi-agent system (MAS) concept. In addition, the practical issues in the development of voltage control systems such as failure of communication or time delay issues are highlighted in this study. The paper also shows the hardware and middleware configuration of the agent manager, local agent and power system simulation program. The performance of the analysis of voltage control system is demonstrated with the practical cases in Gochang Power Testing Center.
