以发电效益最大为目标建立了基于发电权交易的梯级水电站中长期优化调度数学模型,并以清江梯级水电站为例,运用三角旋回算法分别对丰水年、枯水年进行优化调度,取得了较好的效果.与传统的以发电总量最大为目标的调度方法相比,该调度方式可以实现梯级水电站发电总效益最大,增加发电总效益.还具体分析了这两种调度过程,并给出了基于发电权交易下的梯级水电站调度模型能有更好的收益的原因,即避免了与他人分享属于自己的合约电量效益,抓住了转让发电权与受让发电权价格的差异,合理调配了水资源.
Aiming at the maximum benefit of power generation, a mathematic model of long-term optimal operation for cascade hydropower stations based on power generation transaction is established. Taking the Qingjiang Cascade Hydropower Stations as an example, a triangular cycle algorithm is used to optimize the scheduling of wet and dry years, respectively. Good effect.Compared with the traditional scheduling method which aims at the maximum total power generation, this scheduling method can achieve the maximum total power generation efficiency of cascade hydropower stations and increase the total power generation efficiency.At the same time, the two scheduling processes are also analyzed in detail and given The reason for better revenue based on the cascade hydropower station dispatching model under the transaction of power generation rights is that it avoids sharing the contractual power benefit with others and grasps the difference between the transfer power generation rights and the transferee power generation rights price, Water resources.
