Study on the pumped storage power station development model utilizing the lower reservoirs amid the realization of carbon neutrality and carbon peaking goals
Pumped storage is an important part of new energy development.Taking the Chakeng station in Guangdong prov-ince as an example,the paper explored the utilization of the lower reservoirs as a new development model.The results showed that:(1)Using the conventional hydropower station reservoir already built as the lower one,a new reservoir is to be built in the upper stream for the Chakeng pumped storage power station with a proposed installed capacity of 280MW,which is a new exploration of the pumped storage power station construction model.(2)The Chakeng pumped storage pow-er station,when completed,will effectively compensate for the safe and economical operation of the power grid,enhance the system's peak-shaving capacity,and better ensure the stable output of wind-solar combined power generation system in Qingyuan city.(3)The construction of the Chakeng pumped storage power station using the established conventional hydroelectric reservoir features a structurally stable station site,a project area outside ecological protection red line areas,and a land requisition area or site area of 3 682.77 mu(approximately 245.52 hectares).So,there are few constraints on its construction.The utilization of the lower reservoirs method improves the development model of pumped storage power stations and provides a reference for the building of pumped storage power stations of the same kind.
