Limiting wind farms' outputs in valley period of load is common phenomenon with the rapid growth of integrated wind power capacity. The mechanism origin of this phenomenon is analyzed. The marketing pricing model for peak load regulation service is suggested in current generation price regime in order to encourage the voluntary generation company's peak load regulation and lead the wind farm development with the system regulation ability. Based on the current management pattern of peak load regulation services, the basic trading framework design of unconventional peak load regulation service with wind farm participation is proposed. The core issues and solutions are then discussed. The peak load regulation service market with wind farm participation can not only generate price signal, encourage peak load regulation and lead the wind power expansion with the system regulation ability accordantly, but also ensure the economic operation of system. It is compatible with the current policy for supporting the wind power development.%大规模风电并网后,负荷低谷期大量弃风成为电网运行的普遍现象.从机制层面分析了产生弃风现象的根源,提出在现有上网电价制度下,通过市场化的调峰服务定价机制来激励发电企业主动参与调峰、引导风电随电网调峰接纳能力合理发展.在此基础上,通过风电弃风机理的剖析,基于现有调峰管理模式,设计了风电参与的非常规调峰服务交易理论基本框架,并对其中的核心问题及解决方案进行了讨论.风电参与的非常规调峰服务市场既可产生调峰价格信号,激励调峰并引导风电与调峰电源协调发展,还可保证电网经济运行,且与现有风电扶持政策相兼容.
