【摘要】:微電網(wǎng)經(jīng)濟運行涉及對大量場景和方案的分析評價,區(qū)域內(nèi)風電/光伏出力和負荷變化的時序性、周期性和不確定性給微電網(wǎng)運行帶來影響。提出一種典型場景分析方法,對計算周期內(nèi)的大量風電/光伏出力和負荷原始數(shù)據(jù)進行同步聚類劃分,形成能夠反映計算周期內(nèi)歷史數(shù)據(jù)特征的典型場景集;建立包含多種分布式電源和儲能單元的微電網(wǎng)系統(tǒng)經(jīng)濟運行優(yōu)化模型;針對某微電網(wǎng)區(qū)域,比較典型時序場景、全周期時序場景、周期內(nèi)縮減場景3類場景數(shù)據(jù)的經(jīng)濟運行優(yōu)化結(jié)果,驗證所提方法的有效性。
[Abstract]:The economic operation of microgrid involves the analysis and evaluation of a large number of scenarios and schemes. The timing, periodicity and uncertainty of wind / photovoltaic power generation and load variation in the region affect the operation of microgrid. A typical scene analysis method is proposed to cluster the original wind / photovoltaic output and load data in the calculation cycle to form a typical scene set which can reflect the historical data characteristics in the calculation cycle. The economic operation optimization model of microgrid system including multiple distributed power sources and energy storage units is established, and for a microgrid area, the typical time sequence scenario and the whole cycle time sequence scenario are compared. The results of economical operation optimization of three kinds of scene data are reduced in the cycle to verify the effectiveness of the proposed method.
