大规模风电接入给电力系统运行带来很大的不确定性,为维持系统的稳定,保证和扩大风能渗透率,风电提供备用变得至关重要。为调动风力发电企业参与旋转备用服务的积极性,须对其提供补偿。合理的旋转备用定价可以引导风电场和用户合理决策,提高电网运行经济性。基于成本和效益评估的备用服务定价方法,结合我国初级电力市场的情况,提出了风电提供旋转备用服务的机会成本、系统失负荷价值及系统可靠性指标相结合的定价模型,最后通过算例分析验证了上述模型的合理性与有效性。
大規模風電接入給電力繫統運行帶來很大的不確定性,為維持繫統的穩定,保證和擴大風能滲透率,風電提供備用變得至關重要。為調動風力髮電企業參與鏇轉備用服務的積極性,鬚對其提供補償。閤理的鏇轉備用定價可以引導風電場和用戶閤理決策,提高電網運行經濟性。基于成本和效益評估的備用服務定價方法,結閤我國初級電力市場的情況,提齣瞭風電提供鏇轉備用服務的機會成本、繫統失負荷價值及繫統可靠性指標相結閤的定價模型,最後通過算例分析驗證瞭上述模型的閤理性與有效性。

Large scale wind power access has brought great uncertainty to the operation of the power system. To maintain the system stability and ensure wind power penetration, reserve service provided by wind power becomes critical. Wind power as the power supply has the ability to offer spinning reserve. For the enthusiasm of wind power generation enterprises to participate in the spinning reserve service, the enterprises should be given compensation. Reasonable price of spinning reserve can improve the operation economy of power network. In this paper, based on the reserve service pricing method of cost and benefit evaluation, combined with the primary power market in China, a new pricing model is put forward which colligates opportunity cost, VOLL and reliability index of system. Then, an example is given to show the practicability and rationality of the model.
