Research on reactive power optimization of distribution network with distributed photovoltaic
In order to solve the voltage out-of-limit quality problem caused by distributed photovoltaic access to the distribution network,a reactive power optimization mathematical model with the goal of minimi-zing active power network loss and voltage deviation is established.By analyzing the voltage at the photovoltaic grid-connected point,a synergistic control strategy combining weighted voltage-power control and static reac-tive power generator control compensation is proposed.To improve the solving ability of the model,an im-proved particle swarm optimization algorithm is used,and a mutation operation is introduced to prevent the al-gorithm from falling into a local optimum.In order to improve the convergence effect of the algorithm,an im-proved asynchronous learning factor is used.An example verification is conducted in the IEEE-33 node power distribution system,and the results verifies the correctness of the model built in this article and the effective-ness of the proposed strategy.
