为减少微电网弃风,将风电以供热方式接入系统,并引入蓄热储能装置,建立冷热电联供与蓄热储能联合运行模型。与传统模型相比,目标函数在考虑燃料成本、环境成本的基础上,引入弃风成本,量化弃风的经济损失;引入蓄热成本,量化蓄热罐运行过程中的热能损失和电能消耗。在约束中将热平衡约束分为蓄热和放热两种情况处理,准确描述蓄热罐运行特性。仿真结果表明配置成本较低的蓄热罐后,能促进系统风电消纳,具有良好的经济性。

In order to reduce abandoned wind curtailment in microgrid,it is necessary to integrate wind power into power system in the way of hea and introduce heat storage to build up a joint operation model of combining Combined Cooling Heat and Power and heat storage to promote accommodation of wind power.Compared with the traditional model, besides the consideration of fuel cost and environmental cost,the objective function includes the economic losses of wind curtailment and heat storage cost.In the constraint,the heat balance is divided into two kinds of conditions of heat storage and heat release,...
