Capacity price computation of on-stream integral pumped storage hydropower plant considering reservoir capacity lease and hydroelectricity generation profit and loss
摘要
Abstract
Capacity price is an important way to achieve compensating costs and reasonable returns for pumped storage hydropower plant(PSHP).The existing method is mainly applicable to pure PSHP and not to on-stream integral pumped storage hydropower plant(OIPSHP)with specific cost and revenue components.The article first clarifies the diverse cost and revenue components of OIPSHP,including reservoir capacity lease,hydropower gen-eration by surplus water,and hydropower generation profit and loss.Secondly,a short-and long-term multi-scale collaborative peak shaving model of OIPSHP is constructed for cascade hydropower stations with the goal of maximizing the peak shaving benefits.Here,the mixed-integer linear programming method and particle swarm op-timization algorithm are used together to solve above mentioned model.Finally,a capacity price calculation model for OIPSHP is proposed through coupling the multi-scale collaborative peak shaving model and pricing model during operation period considering reservoir capacity lease and hydroelectricity generation profit and loss.The pro-posed capacity price calculation model can provide support for evaluating the economy of PSHP.Taking the OIP-SHP located in the northwest region of China as an example,the results show that the annual hydropower generation by surplus water of OIPSHP reaches 245.2 million kWh,which is far greater than the annual power generation in-crease of hydropower station of upper reservoir of 0.019 million kWh and the average annual power generation of hy-dropower station of lower reservoir decreased by 0.057 million kWh.The reservoir capacity lease amount of OIPSHP is 10.63 million m3.Without considering the reservoir capacity lease and hydroelectricity generation profit and loss,the capacity price of OIPSHP is 730 yuan/(kW·a).When considering both of them,the capacity price is 633 yuan/(kW·a)under the scheme of hydropower price of 0.30 yuan/(kWh)and reservoir capacity leasing unit price of 0.5 yuan/m3,with a decrease of nearly 100 yuan/(kW·a).Hydropower generation by surplus water of OIPSHP is the main factor reducing the capacity price.The reservoir capacity lease cost raises the capacity price.This study complements the capacity price calculation system for PSHP,which can provide technical support for the planning of OIPSHP.关键词
