【摘要】：電力市場(chǎng)的偏差電量考核機(jī)制是現(xiàn)貨市場(chǎng)建立前的過(guò)渡性方案,有利于市場(chǎng)主體參與到公平競(jìng)爭(zhēng)的市場(chǎng)交易中。為了更直觀地體現(xiàn)電力市場(chǎng)偏差電量考核對(duì)售電公司經(jīng)營(yíng)策略的影響,基于參與廣東月度競(jìng)價(jià)交易的電力用戶的實(shí)際電量偏差率數(shù)據(jù)對(duì)2017年2月、3月偏差電量考核情況進(jìn)行分析。在此基礎(chǔ)上,建立偏差考核機(jī)制下售電公司的盈利模型,并以售電公司考核和補(bǔ)償成本最小為目標(biāo)提出考慮免考核電量的可中斷負(fù)荷最優(yōu)購(gòu)買(mǎi)模型。文中設(shè)計(jì)如下3種模擬場(chǎng)景:(1)不捆綁負(fù)荷分別參與市場(chǎng)競(jìng)價(jià);(2)捆綁得到總負(fù)荷參與市場(chǎng)競(jìng)價(jià);(3)捆綁負(fù)荷參與市場(chǎng)競(jìng)價(jià),并采用可中斷負(fù)荷合同減少正偏差電量考核。3種模擬場(chǎng)景對(duì)售電公司運(yùn)營(yíng)策略的影響分析結(jié)果表明,第3種模擬場(chǎng)景下售電公司的盈利最大,為所推薦的最優(yōu)經(jīng)營(yíng)策略。同時(shí)提出了用戶側(cè)月度偏差電量交易模式,以維持系統(tǒng)月度電量平衡。
[Abstract]:The examination mechanism of the deviated electricity quantity in the electricity market is a transitional scheme before the establishment of the spot market, which is conducive to the participation of the main body of the market in the fair competition of the market transactions. In order to reflect more intuitively the influence of the power market deviation electricity quantity examination on the business strategy of the power sale company, Based on the actual electricity deviation rate data of electricity users who participate in the monthly bidding in Guangdong, the paper analyzes the examination of the deviation electricity quantity in February and March 2017. On this basis, the profit model of the power sale company under the deviation assessment mechanism is established, and the optimal purchase model of interruptible load considering the minimum evaluation and compensation cost of the power sale company is put forward. In this paper, three simulation scenarios are designed as follows: (1) unbundled load participates in market bidding; (2) bundling gets total load to participate in market bidding; (3) binding load participates in market bidding. The results show that the third simulation scenario has the largest profit and is the recommended optimal operation strategy by using the interruptible load contract to reduce the positive deviation of electricity quantity. 3 simulation scenarios are used to analyze the impact of the three simulation scenarios on the operation strategy of the power sale company. The results show that the third simulation scenario is the most profitable and the recommended optimal operation strategy. At the same time, the user side monthly deviation electricity trading mode is put forward to maintain the system monthly electricity balance.
