摘要
当前,以风电为代表的新能源快速发展。电网调峰能力不足已成为限制风电消纳的主要因素。组织调峰辅助服务市场,形成市场化的调峰辅助服务价格机制,成为激励传统电源调峰积极性的重要途径,调峰辅助服务需求是风电场参与调峰辅助服务市场的重要基础。本文引入等效负荷率指标,从预期收益角度出发分析风电场调峰公平性;以此为基础,提出了基于等效负荷率分析的风电场调峰辅助服务需求计算方法,以支撑风电场参与市场交易;最后基于IEEE-30节点系统构造算例验证了本文所提出方法的有效性。
At present,new energy such as wind power develops rapidly.The lack of peak auxiliary service capacity has become the main factor of limiting wind power consumption.It is an important way to stimulate the traditional power supply peak by organizing the service market and forming a market-oriented auxiliary service price mechanism.It is an important basis for wind farm to participate in the market of auxiliary service.In this paper,the equivalent load ratio index is introduced,and the fairness of the wind farm is analyzed from the perspective of prospective earnings.Based on the equivalent load rate analysis,the demand calculation method of the wind electric field peak auxiliary service is proposed to support the wind electric field to participate in the market transaction.Finally,the validity of the proposed method is verified based on the IEEE-30 buses system.
