摘要
在风火替代交易机制下,热电厂通过配置储热装置可将其有功出力降低到电网核定的"以热定电"出力水平以下,参与弃风电力消纳。针对热电厂与风电场的调峰交易问题,分析了调峰合作的成本效益、投资模式以及整体和个体角度的发电权可行价格边界;针对投资风险问题,提出了分回收期内和回收期外二阶段进行发电权定价的方式;采用风险价值(Va R)方法描述了调峰合作所面临的未来消纳弃风电量不确定风险。算例分析验证了理论分析的正确性。
CHP（Combined Heat and Power） plant with heat accumulator can reduce its active power output below the level stipulated by the power grid according to the heating load to accommodate the curtailed wind power under the substitution trading mechanism between CHP-plant and wind farm. For the peak regulation trading between them,the cost-benefit of peak regulation cooperation,the investment modes and the feasible whole and individual generation right pricing margins are analyzed. A two-period generation right pricing method is proposed to deal with the investment risk within and beyond the payback period.The Va R（Value at Risk） method is adopted to describe the uncertainty risk for the future accommodation of curtailed wind power during the peak regulation cooperation. Case analysis verifies the correctness of the theoretical analysis.
