The application of distributed photovoltaic system in power grid is more and more extensive. The photovoltaic system has strong volatility and poor stability. Its large-scale access not only increases the complexity of distribution network structure
but also makes the adjustment of power system more difficult
which brings adverse effects to the operation of power grid. This paper mainly studies the cluster partition and reactive power optimization of distribution network with large-scale distributed generation.Firstly
the K-means clustering algorithm improved by PSO is applied to find the better initial clustering center
and then the distribution network is divided into clusters according to the electrical distance between nodes. Aiming at minimizing the total voltage offset of nodes and the active power loss of lines
the dynamic adjustment particle swarm optimization algorithm is used to optimize the reactive power of power system. Finally
the effectiveness of the proposed method is verified by simulation on MATLAB platform.
