摘要

针对无常规电源支撑的风光热储互补发电系统，协调规划装机容量对提高发电系统运行经济性和利用率具有重要意义。提出了一种双层优化配置方法，上层以最小度电成本及弃电率为目标，确定系统装机容量；下层以新能源发电消纳最大为目标，解决功率分配问题。通过反复迭代寻优，得到系统容量配置；然后；通过纳什谈判对优化结果进行选择；最后，对甘肃河西地区数据进行仿真分析。结果表明：风光热储互补发电系统最优容量配置下的度电成本为0.3064元/(k W·h)；风电场加光伏电站装机容量与光热电站装机容量的最优比为6:1，对比相同装机容量的风光互补发电系统，风光热储互补发电系统具有更高的稳定性。

Abstract

For the wind-solar-thermal-storage complementary power generation system without conventional power supply support

coordinated planning of installed capacity is of great significance to improve the operation economy and utilization rate of the power generation system. A two-layer optimal configuration method is proposed. The upper layer determines the installed capacity of the system with the minimum levelized cost of energy and the abandonment rate as the goal. The lower layer aims to maximize the consumption of new energy power generation and solve the problem of power distribution. The system capacity configuration is obtained by iterative optimization. Then

the optimization results are selected through Nash negotiation. Finally

the simulation analysis is carried out with the data of Hexi area in Gansu Province. The results show that

the levelized cost of energy is 0.306 4 yuan under the optimal capacity configuration of the wind-solar-thermal-storage complementary power generation system. The optimal ratio of the installed capacity of the wind farm plus photovoltaic power station to the installed capacity of the photothermal power station is 6:1. Compared with the wind-solar hybrid power generation system with the same installed capacity

the wind-solar-thermal-storage complementary power generation system has higher stability.
