考虑电动汽车用户意愿的热电联供型微电网优化调度

Optimal Dispatch for Microgrids with CHP Considering EV Users' Intention

私家电动汽车(electric vehicle,EV)和分布式电源接入量的增长,给热电联供型微电网调度提出了难题。因此,在含可再生能源的热电联供型微网模型基础上,考虑用户行为意愿,根据用户选择的不同充放电行为将电动汽车分类建模。随后,建立了基于分时电价的含电动汽车的热电联供型微网系统的多目标运行优化模型,通过模糊数学方法将多目标模型转化为单目标模型。算例分析中,对构建的4种不同场景运用Yalmip/Gurobi进行优化,分析对比了各场景下的优化结果,验证了所建模型及优化结果的合理性。

The increasing of access number which including private electric vehicles and distributed power posed a question to microgrids with combined heat and power（ CHP）. Therefore,On the basis of the microgrid model with CHP and renew able energy,considering the users＇ intention,the electric vehicles（ EVs） are modeled according to different charging and discharging behaviors selected by users. And then,a multi-objective optimization model is established including microgrids with CHP and EVs considering time of use（ TOU） tariff,and it is then transformed into a singleobjective model by the method of fuzzy mathematics. In the analysis of this model,four different scenes are optimized by Gurobi Solver. The rationality of model and results are verified by comparing optimization results under the four scenes.
