發(fā)布時間：2021-03-06 23:37
電力系統(tǒng)中分布式發(fā)電（DG）的不斷增長導致了微電網應用的不斷擴展。一般而言,微電網系統(tǒng)中包含分布式發(fā)電機組、儲能設備和可控負載等元件,并能夠在并網和孤島等模式下運行。微電網的經濟運行是通過能量管理系統(tǒng)實現(xiàn)的,該系統(tǒng)可以優(yōu)化調度分布式發(fā)電和儲能設備,并持續(xù)平衡供需。本文提出了一種在并網微電網中DG的最優(yōu)機組組合和經濟調度方案�；旌险麛�(shù)線性規(guī)劃（MILP）用于實現(xiàn)最優(yōu)資源調度模型,目的是通過儲能設備和熱電聯(lián)產（CHP）發(fā)電機組等資源經濟調度來最小化系統(tǒng)總體運行成本。文中所提出的能量管理系統(tǒng),還考慮了 DG機組運行、電池充電/放電限制和充電狀態(tài)（SOC）限制等約束條件,基于算例進行了仿真驗證。仿真結果表明,通過使用所提出的策略對能量存儲系統(tǒng)和CHP機組進行最優(yōu)調度,有效地降低了系統(tǒng)的運行成本。文中所提出的微電網能量管理系統(tǒng),可以有效的為微電網的高效運行提供支撐。
