分時電價環(huán)境下基于家居能量管理系統(tǒng)的家居負(fù)荷建模與優(yōu)化運行
[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.
