【摘要】：微電網(wǎng)經(jīng)濟(jì)運(yùn)行涉及對(duì)大量場(chǎng)景和方案的分析評(píng)價(jià),區(qū)域內(nèi)風(fēng)電/光伏出力和負(fù)荷變化的時(shí)序性、周期性和不確定性給微電網(wǎng)運(yùn)行帶來(lái)影響。提出一種典型場(chǎng)景分析方法,對(duì)計(jì)算周期內(nèi)的大量風(fēng)電/光伏出力和負(fù)荷原始數(shù)據(jù)進(jìn)行同步聚類劃分,形成能夠反映計(jì)算周期內(nèi)歷史數(shù)據(jù)特征的典型場(chǎng)景集;建立包含多種分布式電源和儲(chǔ)能單元的微電網(wǎng)系統(tǒng)經(jīng)濟(jì)運(yùn)行優(yōu)化模型;針對(duì)某微電網(wǎng)區(qū)域,比較典型時(shí)序場(chǎng)景、全周期時(shí)序場(chǎng)景、周期內(nèi)縮減場(chǎng)景3類場(chǎng)景數(shù)據(jù)的經(jīng)濟(jì)運(yùn)行優(yōu)化結(jié)果,驗(yàn)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.
