发布时间：2018-10-08 11:14
【摘要】：电力市场的偏差电量考核机制是现货市场建立前的过渡性方案,有利于市场主体参与到公平竞争的市场交易中。为了更直观地体现电力市场偏差电量考核对售电公司经营策略的影响,基于参与广东月度竞价交易的电力用户的实际电量偏差率数据对2017年2月、3月偏差电量考核情况进行分析。在此基础上,建立偏差考核机制下售电公司的盈利模型,并以售电公司考核和补偿成本最小为目标提出考虑免考核电量的可中断负荷最优购买模型。文中设计如下3种模拟场景:(1)不捆绑负荷分别参与市场竞价;(2)捆绑得到总负荷参与市场竞价;(3)捆绑负荷参与市场竞价,并采用可中断负荷合同减少正偏差电量考核。3种模拟场景对售电公司运营策略的影响分析结果表明,第3种模拟场景下售电公司的盈利最大,为所推荐的最优经营策略。同时提出了用户侧月度偏差电量交易模式,以维持系统月度电量平衡。
[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.
