Abstract

With the rapid development of the world economy, the problem of energy crisis and environmental pollution is increasingly prominent. The traditional power generation mode not only consumes a lot of energy, but also causes a lot of pollution. Although distributed power supply brings benefits to people, due to the randomness and volatility of distributed power supply and the lack of unified grid-connected management system, the access of a large number of distributed power supply seriously affects the static voltage stability in the grid-connected area, resulting in voltage fluctuations, such as frequent high-voltage problems. Therefore, simulation research based on Matlab/Simulink platform is conducted in this paper. By changing the capacity and position of the distributed power supply connected to the distribution network, the optimal position and capacity of the distributed power supply connected to the distribution network are sought, so that the voltage on the distribution network is relatively stable at this time.
