针对“三北”地区电网热电机组比重大、纯凝机组等非供热机组承担系统调峰的问题，提出有偿调峰服务费用的计算方法。在对纯凝机组和热电机组分别建模基础上，构建一种电负荷由全网机组平衡、热负荷由各热电厂就地平衡的优化调度模型。通过求解热电机组按纯凝发电和热电联产两种方式运行时系统各机组的出力，分别确定纯凝机组、风电机组以及水电机组的深度调峰容量，并将非供热机组深度调峰区间内销售电量所得利润之差定为有偿调峰费用。算例分析证明了该有偿调峰费用计算方法的合理性。
針對“三北”地區電網熱電機組比重大、純凝機組等非供熱機組承擔繫統調峰的問題，提齣有償調峰服務費用的計算方法。在對純凝機組和熱電機組分彆建模基礎上，構建一種電負荷由全網機組平衡、熱負荷由各熱電廠就地平衡的優化調度模型。通過求解熱電機組按純凝髮電和熱電聯產兩種方式運行時繫統各機組的齣力，分彆確定純凝機組、風電機組以及水電機組的深度調峰容量，併將非供熱機組深度調峰區間內銷售電量所得利潤之差定為有償調峰費用。算例分析證明瞭該有償調峰費用計算方法的閤理性。

According to the fact that“The Three Norths"regional power grid contains a large proportion of thermoelectric units, and the peaking task is mainly assumed by condensing units, a peaking cost calculation method is proposed. An optimal dispatching model is built up based on the modeling of the condensing units and thermoelectric units. In this model, power load will be balanced by units in whole network, while heat load will be balanced on the spot by each thermal power plant. By solving the power outputs of all units in two different modes, the peak-regulating capacity of all units can be analyzed. Peaking cost is defined as the difference of power profit among depth peaking intervals of non thermoelectric units. The reasonableness of the calculation method is shown by an example.
