为缓解系统中有限装机容量与一定的备用容量要求之间的矛盾,根据电力用户可以采取积极措施主动进行负荷管理而为系统提供备用容量的思想,提出一种基于最优潮流的能量和备用容量市场联合优化模型;研究在双侧开放的电力市场环境中,用户主动参与备用容量服务对市场运营效益的影响。IEEE 30节点系统算例表明,用户进入旋转备用容量市场,成为系统备用容量的新供应者,可使全系统的运营效益有较大提高,减少了系统备用容量购买支出,降低了各节点上的电价水平和系统备用价格。
In order to alleviate the contradiction between the limited installed capacity of the system and some spare capacity requirements, according to the idea that power users can take active measures to take the initiative to carry out load management to provide backup capacity for the system, an optimal power flow and spare capacity Market joint optimization model; study the impact of the user’s active participation in reserve capacity service on the market operation benefit in the bilateral open electricity market environment. The example of IEEE 30-bus system shows that when users enter the market of rotating spare capacity and become the new supplier of system spare capacity, the operational benefits of the whole system can be greatly improved, the purchase cost of system spare capacity can be reduced, and the cost of each node Price level and system reserve price.
