Research on Reactive Power Compensation of Distribution Network Considering Wind Turbine Access

Abstract

In response to the concept of green low-carbon environmental protection, more and more distributed generations are connected to the distribution network. However, with the integration of various distributed energy into the distribution network, the safe and stable operation of the power system will be affected <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</sup> . This paper studies the reactive power compensation of distribution network with distributed wind power. Based on the traditional reactive power optimization model, the reactive power optimization mathematical model of distribution network is established. The objective function is network loss and voltage offset, and the constraint conditions are node voltage, reactive power compensation capacity and transformer ratio <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[2]</sup> . Firstly, the network loss and voltage change of distribution network after wind power integration are analyzed, and then the reactive power compensation device is used to optimize. A hybrid particle swarm optimization algorithm is used to verify the IEEE30 node system. The results show that the algorithm can significantly reduce the distribution network loss, improve voltage quality, reduce investment costs, and has good economy.
