Active Power Distribution Networks with Decentralized Multi-Agent Control Mode. Part 2

Abstract

The article considers the solution of system tasks concerned with controlling the overall mode of an electric network with distributed generation: maintaining active and reactive power balances in normal modes, emergency control when large disturbances of the normal mode occur, maintaining the power supply system operability in post-emergency modes, restoring the power system integrity and normal operation after it was disintegrated into isolated parts by an accident or emergency control system operation. Methods of solving these tasks in a decentralized manner are proposed, which have been tested on physical models of power systems and in a pilot project on Minigrid. The developed Minigrid is integrated with an external electric network using a control system that is an agent of a multiagent system. A conclusion is made about the possibility of developing a technology for decentralized control of the modes of electric networks with distributed small generation sources. In the first part [1], the terminology used is given, the concept of a subject of the multiagent control system of electric networks with distributed generation is given, and matters concerned with multiagent decentralized control of frequency and voltage in such networks are considered. The second part of the article presents the results of a study, on an active electric network physical model, of decentralized multiagent restoration of the integrity and normal operation of the network after its disintegration into isolated parts by an accident or emergency control system operation.
