摘要
建立了考虑需求侧管理的微网经济优化模型。将微网的电力负荷分为3个部分:固定负荷、可转移负荷、随机负荷,其中可转移负荷的管理是需求侧管理的主要内容,也是微网经济优化运行的重要目标。在分时电价的环境下,建立了微网中分布式电源与需求侧负荷优化管理的协调运行模型。通过函数线性化将该优化问题转化为一个混合整数规划问题,采用专业混合整数规划软件求解。仿真结果表明,考虑需求侧管理的微网经济运行相比不考虑时的总费用减少了3.83%,具有较好的经济效益。
An economic scheduling model for a microgrid is proposed by considering demand side management. Three types of loads, i.e., fixed, transferable, and user-action loads, are considered, and the management of transferable load is especially significant in the demand side management. In the case of time-of-use price, the formula of demand side management is described, and the harmonization scheduling model of the distributed generations with demand management is established. Function linearization facilitates converting the optimization case into a mixed-integer linear programming, and a commercial mixed-integer linear programming software is applied to solve the programming problem. The numerical tests for a microgrid indicate that with demand side management consideration, the total cost reduces by 3.83%.
