提出了电力库联营情况下水电竞争上网的方式和定价方法。水电仅通过申报日上网电量与容量参与竞争上网。电力交易中心遵循的基本原则是优先使用水电 ,但是水电上网电价由其等值火电的上网电价决定。首先在峰修整去除水电后的剩余负荷曲线上 ,按火电竞价上网的实用当量电价法确定火电机组的最优加载顺序和上网电价 ,然后将水电机组插入剩余负荷曲线 ,确定水电机组的加载位置 ,并以相邻火电机组的上网电价的加权平均作为其上网电价。最后讨论了水电的年收支平衡问题 ,并给出了说明性算例
The ways and pricing methods of hydropower competition for access to the Internet in the case of electricity pool joint ventures are proposed. Hydropower only competes online by reporting on-grid power and capacity. The basic principle followed by the power trading center is to give priority to the use of hydropower, but the on-grid electricity price of hydropower is determined by the on-grid electricity price of its equivalent thermal power. Firstly, after the peak dressing removes the hydropower residual load curve, the optimal load sequence and the on-grid tariff of the thermal power unit are determined according to the practical equivalent power price method for thermal power grid surfing. Then the hydropower unit is inserted into the residual load curve to determine the loading position of the hydropower unit. The weighted average of the on-grid tariffs of neighboring thermal power units is used as their on-grid tariff. Finally, the annual balance of hydropower is discussed and an illustrative example is given.
