摘要 动力系统是机(包括位能、动能、光能、热能等外力)和电(电磁能)关联的有机构成,电力系统是其重要组成部分之一,其功能是完成一个机-电-机的动力平衡。电力系统调度涉及满足机功率平衡的经济调度和以电功率为核心的、牵制这一机功率平衡的电压支撑问题,两者间有机关联,不能分离。由此,以应对不确定性为背景,以源(发电与负荷间机功率)平衡的实现为线索,提出一种新的电力系统调度模型,该模型充分计及电压调节效应,并有效考虑备用响应,统筹考虑源平衡及其电压支撑,目的在于挖掘电力系统消纳不确定性的协同能力。针对该模型,给出了带精英策略的快速非支配排序遗传算法和蒙特卡洛模拟非线性优化并行组合求解方法。算例分析表明了调度中计及电压调节效应以增强源平衡能力的可靠性和有效性。

Abstract:The power system is characterized by associating mechanical energy (including potential energy,kinetic energy,light energy,and thermal energy,etc.) and electromagnetic energy,and its function is to realize the balance between mechanical power and electrical power.The power system dispatch involves the economic dispatch to achieve the balance of mechanical power and the voltage support problem that takes electrical power as the kernel and links the mechanical power balance.These two parts are interrelated and inseparable.Taking the accommodation of injection uncertainties as the background and the realization of source power (i.e.mechanical power of the supply and the demand side) balance as the clue,a novel dispatch model is proposed,in which the voltage regulation effect and the unit reserve response mechanism are well considered.Additionally,the source power balance and its voltage support are effectively integrated to exploit the potential synergistic capability of the power system to accommodate the injection uncertainties.Then a parallel solution methodology formed by the combination of the fast and elitist non-dominated sorting generic algorithm (NSGA-Ⅱ) and the Monte Carlo simulation with nonlinear programming is proposed for the model.Finally,validity and effectiveness analyses are conducted for several cases.Presented analyses demonstrate that the proposed model can take the advantage of the voltage regulation effect to keep the balance of source power under uncertainty.
