Multi-agent system based distributed voltage control in medium voltage distribution systems

Due to the penetration of Distributed Generation (DG), distribution systems are advancing towards the smart grid technologies for voltage control strategies. In this paper, a Multi-Agent System (MAS) Based, two stage algorithm is proposed that removes the inadmissible voltages on the nodes of distribution system, in distributed manner. Furthermore, the algorithm also minimizes the overall losses. The proposed scheme utilizes minimum data in the voltage control strategies. The effectiveness of the proposed method is investigated by conducting simulations in Matlab software, on a typical Finnish residential medium voltage distribution system with varying DG penetration. Results indicate validity of the approach in distributed voltage control and give the sensitivity analysis based on DG penetration for both stages.
