摘要/Abstract

摘要： 为了改善新能源的反调峰特性，提出了面向不同用户群体的需求响应（demand response，DR）模型，同时对储能系统（energy storage system，ESS）及微电网2个可控单元建模，与新能源出力协调配合以促进大规模新能源并网。考虑到DR项目的用户参与度，设计了用户满意度函数作为约束条件，并以峰谷比和新能源消纳率作为评价指标，建立了综合考虑以系统经济成本最低、污染排放最少和机组出力最稳定为目标的优化调度模型，采用YALMIP工具箱和CPLEX程序对模型进行求解。模拟结果表明所提模型可以有效提高新能源的消纳水平，减少污染排放，降低峰谷比，提高电力系统的安全稳定性。

Abstract: In order to improve the anti-peak-shaving characteristic of new energy, a demand response（DR） model for different users is proposed. At the same time, two controlled units of energy storage system （ESS） and microgrid are modeled, and they are coordinated with new energy output to promote the integration of large-scale new energy. Considering the user's participation degree of DR project, the user satisfaction function is designed as a constraint. In addition, peak-to-valley ratio and new energy consumption rate are taken as the evaluation indexes. A optimization scheduling model considering the minimum cost of power system, the least pollutant emissions and the most stable output of units is established. The YALMIP toolbox and CPLEX program are used to solve the model. Simulation results show that the proposed model can effectively improve the consumption level of new energy and reduce the pollutant emissions and peak-to-valley ratio, thus the security and stability of the system may be improved.

Key words: demand response（DR）, direct load control, transferable load, energy storage system（ESS）, microgrid, new energy consumption
