Distribution Network Secondary Coordinated Voltage Control Based on Multi-Objective Linear Programming

Distribution network with a large number of Distributed Generators (DG) puts forward higher requirements for coordinated control of voltage and reactive power. Secondary coordinated voltage control is an effective method to improve distribution network voltage level under the condition of high permeable DG. Based on the basic principle of the secondary coordinated voltage control, multi-objective linear programming method is used to solve the contradiction between the safety and the economy of the distribution network, and the optimization goal construction, control strategy selection and control process realization are introduced respectively. The simulation results show that the secondary coordinated voltage control based on multi-objective programming can be used to solve distributed network voltage stability, but also can improve the efficiency of ADN.
