Abstract
In order to coordinate the reactive power output of distributed generator (DG) and traditional reactive power compensation device, a multi-objective reactive power optimization mathematical model for distribution system with DGs is established. The minimum network loss, minimum voltage deviation and minimum capacity of reactive power compensation devices are taken as the objective functions. Analytic Hierarchy Process (AHP) is used to determine the weight of the sub-objective functions and improved particle swarm optimizer based on constrict factor (PSOCF) is used to optimize the model. Optimization is based on the IEEE 33-bus system, and results show that the model built in this paper can effectively reduce the network loss, improve the voltage quality, optimize the capacity of reactive power compensation device, and provide optimization schemes with different optimization requirements for decision makers.
