摘　　要：针对北方地区冬季大规模弃风现象,在热电储风电消纳系统的基础上,提出了一种考虑用户满意度的热电储系统的日前优化调度方法。首先分析热电储系统的构成及风电消纳机理,然后建立了考虑用户用电经济度、用电舒适度以及热舒适度的电热满意度模型。在此基础上以用户电热满意度和系统发电成本为目标函数,建立了考虑用户满意度的热电储系统日前优化调度模型,在保证用户热舒适度和用电稳定的前提下,调节用户的电热满意度,提高风电接纳空间。最后采用粒子群优化算法进行仿真求解,仿真结果验证了通过调节用户电热满意度能够进一步提高热电储系统的风电接纳空间,同时降低系统的发电成本。Aiming at the phenomenon of large-scale wind power abandonment in winter in northern areas,a day-ahead optimization scheduling method considering user satisfaction is proposed based on the wind power absorption of thermoelectric storage system.The structure of thermoelectric storage system and the mechanism of wind power absorption are firstly analyzed,and then,an electrical and thermal satisfaction model considering the economic degree of electricity,the comfort degree of electricity and the comfort degree of heat is established.On this basis,a day-ahead optimization scheduling model of thermoelectric storage system is established with user satisfaction and power generation cost as objective functions,and under the premise of ensuring user thermal comfort and electricity consumption stability,user satisfaction is adjusted to improve the acceptance space of wind power.The particle swarm optimization algorithm is used for the simulation solution.The simulation results verify that the wind power acceptance space of the thermoelectric storage system could be further improved and the generation cost of the system could be reduced by adjusting the user's electrical and thermal satisfaction.
