What factors affect the economic benefits of pumped storage power stations?
In addition, under the three development models, the three factors of capacity electricity price, capacity ratio covered by approved electricity price, and energy conversion efficiency also impact the economic benefits of pumped storage power stations. 1. Introduction
What is the Auxiliary Service income of central China pumped storage power station?
Under the “two-part electricity price” development model, the annual electricity income is ¥45.931 million, and the annual auxiliary service income can be the auxiliary service income of the above-mentioned Central China pumped storage power station in , which is ¥805.1 thousand.
What are the development models of pumped storage power stations?
According to the different stages of the development of the power market, this paper puts forward the corresponding development models of pumped storage power stations, which are successively the “two-part price system” model, the “partial capacity fixed compensation” model, and the “completely independent market participation” model.
How can pumped storage power stations be fully independent?
In the model of “completely independent participation in the market”, the technical transformation of the pumped storage power station should be accelerated, the energy conversion efficiency of the power station should be reasonably improved, the power loss should be reduced, and the cost recovery of the power station should be promoted.
What is the operation model of Japan's pumped storage power station?
The operation model of Japan’s pumped storage power station mainly includes a leasing system and an internal accounting system. In the lease system, according to the principle of cost-ism, the lease fee is a fixed electricity fee based on the construction fee of the power station.
What is the price mechanism of pumped storage power stations?
In terms of the pumped storage price mechanism, most of the existing studies focus on the price mechanism of pumped storage power stations at a certain stage, including the current two-part price mechanism and the bidding mechanism under the market environment, and the horizontal comparison of the multi-stage price mechanism is lacking.
