提出一种同时包含蓄电池储能和负荷转移的微网经济运行优化方法. 该方法将全天24 h划分为谷平峰3种时段,在谷平时段设计蓄电池充电补偿函数、放电罚函数,峰时段设计蓄电池充、放电罚函数;同时将部分负荷从峰时段转移到谷平时段. 通过引导微网在不同时段合理对蓄电池进行充放电、向电网进行购售电,不仅减少了微网经济运行费用,而且对电网起到"移峰填谷"作用. 利用LINGO优化软件对混合整数、非线性组合模型进行求解. 结果表明,微网全天经济运行费用减少了13.4%,具有较好的经济效益.
提齣一種同時包含蓄電池儲能和負荷轉移的微網經濟運行優化方法. 該方法將全天24 h劃分為穀平峰3種時段,在穀平時段設計蓄電池充電補償函數、放電罰函數,峰時段設計蓄電池充、放電罰函數;同時將部分負荷從峰時段轉移到穀平時段. 通過引導微網在不同時段閤理對蓄電池進行充放電、嚮電網進行購售電,不僅減少瞭微網經濟運行費用,而且對電網起到"移峰填穀"作用. 利用LINGO優化軟件對混閤整數、非線性組閤模型進行求解. 結果錶明,微網全天經濟運行費用減少瞭13.4%,具有較好的經濟效益.

A method of economic operation optimization for micro-grid with battery storage and load transfer is pro-posed, which divides the whole day into valley period, normal period and peak period, and designs battery charge compensation function and discharge penalty function at valley and normal periods and designs charge compensation and penalty function at peak period.Micro-grid is reasonably guided to charge and discharge battery, purchase and sell electricity to the main grid at different periods, which not only reduces the micro-grid economic operation cost, but also helps the"peak clipping and valley filling" of main grid.LINGO optimizing software is applied to solve the mixed-integer and nonlinear models.The result indicates with the battery charge and discharge management and load transfer, micro-grid economic operation cost throughout the day reduces by 13.4%,which has good economic benefit.
