Operation Optimization and Control of Distribution System Composed of Multiple Distributed Generations

To improve the performance of the microgrid with multi-inverted distributed power supply in different modes, the micro-grid operation characteristics are analyzed, and the objective function of the micro-grid system operation is established. Combining PSCAD/EMTDC with MATLAB advantages, the control parameters are optimized by using genetic algorithms. The inverter output impedance is analyzed in the frequency domain, and the feasibility of the droop characteristic applied to the low-voltage microgrid is verified. The simulation results of the case show the feasibility and effectiveness of the control strategy.
