引入柔性电热负荷参与到综合能源系统的调度中,综合考虑源-荷两侧,供能侧构建了由光伏机组、能量转化装置和储能系统组成的多能源系统模型,需求侧构建了可平移、可转移和可削减柔性电负荷与耦合室内外温度的柔性热负荷模型.以系统日运行成本最低为优化目标,分别对供能侧与需求侧设备出力和柔性负荷的用能时间与负荷大小进行了优化.对北京市某社区综合能源系统的优化调度进行了研究.结果表明:柔性负荷参与调度能够降低负荷波动,热负荷峰值由原来的3 876.80 kW下降到3 822.11 kW,减少了 54.69 kW;电负荷的峰谷差从1 488.81 kW下降到1 382.69 kW,波动率下降了7.1％;源-荷两侧共同参与优化调度能够提高系统经济效益,系统成本比原来降低了2.26％.
Optimal operation method of integrated energy systems considering flexible load regulation of demand side
In this paper,the flexible electrical and heating loads are introduced to participate in the dispatch of the integrated energy system.The source-load sides are comprehensively considered.A multi-energy system model composed of photovoltaic units,energy conversion devices and energy storage systems is constructed on the energy supply side.A flexible heating load model that can be translated,transferred and can reduce the flexible electrical load and couple indoor and outdoor temperature is established on the demand side.Taking the lowest daily operation cost of the system as the optimization goal,the energy use time and load size of equipment output and flexible loads on the energy supply side and demand side are optimized,respectively.This paper studies the optimal dispatch of the integrated energy system in a community in Beijing city.The results show that flexible load participating in dispatch can reduce the load fluctuation.The peak value of heating load decreases from the original 3 876.80 kW to 3 822.11 kW,with a decrease of 54.69 kW.The peak-to-valley difference of electrical load decreases from 1 488.81 kW to 1 382.69 kW,and the fluctuation rate decreases by 7.1％.The participation of both source-load sides in the optimal dispatch can improve the economic benefits of the system,and the system cost is reduced by 2.26％compared with the original.
