Optimizing Distributed Energy Resource Control System Architecture

Abstract

This paper explores an optimized control system architecture designed to improve load matching in distribution networks. Below transmission voltages energy management systems may not have provisions for automated generation control. Distributed energy resources (DER) connected at distribution voltages need improved control schemes. This paper proposes a centralized control node located at distribution substations, which employs cyber security best practices using fiber or wireless networks, to centralize DER controls at the substation level. This allows multiple generation facilities to use a single point of control to optimize load matching while simultaneously simplifying utility dispatch.
