Embodiment Construction
[0018] The specific embodiment of the present invention will be described with reference to the accompanying drawings.
[0019] Analyze the actual data of Dabancheng wind farm in Xinjiang, and use PSASP to calculate the power flow according to the position information of each particle in the IEEE-30 node system, and calculate the active and reactive power flow of the line, the voltage amplitude, phase angle and active network loss of each node. As a result, preparations are made for reactive power optimization of subsequent nodal systems. Specific process such as figure 1 shown.
[0020] The improved differential evolution algorithm is applied to the reactive power optimization of the wind farm power system, and the optimization simulation calculation is carried out on the IEEE-30 node system. The simulation results can verify the feasibility and effectiveness of the differential evolution algorithm.
