摘要:
      智能软开关作为一种新型配电装置,其应用将极大地提高配电系统运行的经济性、灵活性和可控性。该文提出了一种考虑智能软开关和传统无功补偿装置并存的多手段互补的电压控制方法,构建了兼顾配电网运行经济性与系统电压水平的双层运行优化模型;然后针对该模型提出了一种基于遗传算法和内点法的混合求解策略,并采用预动作表法确定离散设备的动作时刻,同时根据智能软开关的功率储备对预动作时刻表作出动态调整;最后,在改进的IEEE33节点系统中,对所提出的运行优化模型进行验证和分析。仿真结果表明,智能软开关与无功补偿装置的组合能够有效应对源-荷不确定变化引起的电压波动,显著提高电网的稳定运行水平与能量传输能力。
Abstract:
      As a new type of power distribution device, the soft open point (SOP) will greatly improve the economical, flexible and controllable operation of the distribution network. Firstly, a multi-method interaction voltage control strategy considering the coexistence of SOP and traditional reactive power compensation devices is proposed, and a bi-level optimization model that combines the economical operation with the system voltage level is constructed in this paper. Then a hybrid solution strategy based on genetic algorithm and interior point method is proposed for the model. The pre-action table is used to determine the action time of discrete devices, and the pre-action timetable is adjusted according to the power reserve of the SOP. Finally, in the improved IEEE33 node system, the proposed optimization model is analyzed and verified. The simulation results show that the combination of SOP and reactive power compensation devices can effectively deal with the voltage fluctuation caused by the source-load uncertainty change, and significantly improve the stable operation level and energy transmission capacity of the power grid.
