摘要
为了提升虚拟电厂(virtual power plant,VPP)的经济效益,促进风、光等清洁能源的消纳,文章设计了一种基于混合灰狼(hybrid grey wolf optimization,HGWO)算法的VPP经济调度模型。将VPP运行成本最小作为目标函数,利用HGWO算法对目标函数进行最优值搜索,算例结果显示,HGWO算法收敛时的进化代数和收敛时间分别为55代和12.15 s,获得的VPP最小运行成本为57.36万元,以及HGWO算法的各项性能指标均优于文章所列出的其他3种算法;同时也表明了通过科学调度VPP内部的各类分布式电源,不仅满足了VPP负荷需求,而且使风电场和光伏电站的输出电能得到了充分利用,进而提升了VPP的经济性。
In order to improve the economic benefits of the virtual power plant(VPP)and promote the consumption of clean energy such as wind and solar power,this paper designs a VPP economic scheduling model based on the hybrid grey wolf optimization(HGWO)algorithm.The objective function is to minimize the operating cost of VPP,and the HGWO algorithm is used to search for the optimal value of the objective function.Simulation results show that the evolutionary algebra and convergence time of the HGWO algorithm are 55 times and 12.15 seconds,respectively,and the minimum operating cost of VPP obtained is 573600 yuan.The performance indicators of the HGWO algorithm are superior to the other three comparative methods.It also shows that by scientifically scheduling various distributed power sources within VPP,not only is the load demand of VPP met,but also the output energy of wind farms and photovoltaic power plants is fully utilized,thereby improving the economy of VPP.
