Modeling and Analysis of AC Distribution Grids with Wind and Solar Storage

To analyze the power quality issues induced by the distributed wind-solar-storage in the distribution power network, this paper constructs an AC distribution network model including the wind-solar-storage, and analyzes the power quality in the wind-solar-storage grid-connected system. Firstly, this paper constructs the wind power model and the solar-storage model using the MATLAB/Simulink respectively. And then, a joint simulation model of the AC distribution power network with wind-solar-storage is constructed. Finally, the simulation results indicate that wind-solar-storage may cause the power quality issues due to the coupling between AC and DC in the distribution network.
