Digital Simulation Analysis of Influence of Distributed Wind Power Generation connected on node voltage of Distribued Network

Analysis of the influence of large‐scale offshore wind power on the steady‐state voltage of the vicinity region of grid connection point

“…The voltage distribution of each bus in transmission and distribution systems highly depends on the direction of power flow, and the access of distributed generation will directly determine the flow direction, so the randomness of distributed wind turbine output will make the power loss of the transmission line change accordingly. References [8–11] study the distribution network model and analyze the influence of distributed wind power on the steady‐state voltage of distribution network. In view of the fact that the traditional evaluation method of static voltage stability zone ignores the influence of capacitance parameters, and the stability criterion fails after the d ‐axis current is saturated, which leads to the large deviation of the evaluation results, an improved characterization method of static voltage stability zone of offshore wind power is proposed in [12], which considers the cable capacitance parameters and the saturation effect of converter.…”
