考虑柔性电负荷和热负荷的综合能源系统容量优化配置
摘要：柔性负荷参与调度能够削峰填谷、优化负荷曲线，降低系统成本。考虑可平移负荷、可转移负荷和可削减负荷建立了电力柔性负荷模型；根据用户对温度感知的模糊性建立了热力柔性负荷模型；采用混合整数线性规划方法，以经济成本最小和一次能源消耗量最少为目标，对综合能源系统进行配置优化，得到各个设备的最佳容量和各时段出力。算例结果表明，通过调度柔性电负荷和灵活调整室内温度，可促进可再生能源消纳、优化电负荷和热负荷曲线，从而提高风机装机容量、降低燃气轮机容量和蓄热罐容量、提高系统经济性、降低一次能源消耗量、提高可再生能源渗透率。
Abstract:Flexible load participating in scheduling can contributes to peak-load shifting, optimize load curve and reduce the cost of system. Considering translational load, transferable load and reducible load, a flexible power load model was established. According to the fuzziness of user’s perception on the temperature a flexible thermal load model was built. Adopting mixed integer linear programming method and taking minimum economic cost and least primary energy consumption as the objectives, the configuration of the integrated energy system was optimized to obtain the optimum capacity of each equipment and its output in each time-interval. Results of calculation example show that by means of scheduling flexible electrical load and flexibly adjusting indoor temperature, the consumption of renewable energy sources can be promoted, the electrical load curve and the thermal load curve can be optimized, thus the installed capacity of wind turbines can be increased and the capacities of both gas turbines and heat storage tanks can be reduced, the economy of system can be improved, besides, the consumption of primary energy source can be reduced and the penetration rate of renewable energy source can be increased.
