Optimal Configuration of Active-reactive Power Sources in Distribution Network With Photovoltaic Generation
摘要
Abstract
According to the situation that photovoltaic (PV) generation penetration increases gradually and the reactive regulating capability of PV generation is not fully considered in distribution network planning, this paper studied compre-hensive configuration of PV generation, which provides active and reactive power, and switch capacitor, which provide reactive power. Considering the time-sequence characteristic and randomness of load and solar, multi-state model in different periods was established. A bi-level programming model embedding chance constrained programming was proposed, which considers reactive regulating capability of PV generation and adjustment of electrical source output with load changing during operation. The model takes the minimum annual cost above confidence level as the upper level planning objective function, the minimum annual operation cost above confidence level as lower level planning objective function. The elitist strategy genetic algorithm based on segmented chromosome coding was applied for solving bi-level programming model. The simulation results of example show that comprehensive optimal configuration of PV generation and switch capacitor can enhance the utilization of active-reactive power sources as well as reduce investment and operation costs, and it is helpful for the safe and economic operation of distribution network to make full use of PV generation’s reactive potential. Meanwhile, better investment and operation benefits can be obtained when incorporating PV generation with controllable sources such as micro-gas-turbine (MGT).关键词
