【摘要】：分时电价反映了电能商品的时间差价,可以更好地鼓励用户合理安排用电时间,削峰填谷,提高电力资源的利用效率;家居能量管理系统(home energy management system,HEMS)的研发与可变电价环境下家居负荷的优化方法成为影响分时电价应用效果的关键因素。为此,文章在HEMS的基础上研究了如何给出家居设备的优化运行方案以应对多变的分时电价。首先,给出了家居设备的负荷特性描述,通过各类特性的搭配对常见家居设备进行建模;然后,建立了分时电价环境下的家居设备优化运行决策模型,模型以最小化用户电能成本与最小化峰谷差为目标,综合考虑多类设备以及分布式新能源的协调;最后进行算例仿真,对比分析了多种场景下的优化决策结果,验证了优化运行决策模型在控制用户电能成本及减小峰谷差方面的作用。
[Abstract]:The time-sharing price reflects the time difference price of the electric energy commodity, which can encourage the user to arrange the electricity time reasonably, cut the peak and fill the valley, and improve the utilization efficiency of the power resource. The research and development of home energy management system (home energy management system,HEMS) and the optimization method of household load in the environment of variable electricity price become the key factors that affect the application effect of time-sharing electricity price. Therefore, based on HEMS, this paper studies how to give the optimized operation scheme of household equipment to deal with the changeable time-sharing price. Firstly, the load characteristic description of household equipment is given, and the common household equipment is modeled by the collocation of all kinds of characteristics. Then, the optimal operation decision model of household equipment in time-sharing electricity price environment is established. The model aims at minimizing the power cost of users and minimizing the peak and valley difference, and considers the coordination of multi-types of equipment and distributed new energy synthetically. At last, an example is given to compare and analyze the results of optimization decision under various scenarios, and verify the function of the optimal operation decision model in controlling the power cost of users and reducing the peak-valley difference.
