Income compensation method suitable for new energy and pumped storage combined power generation

Abstract

The invention discloses an income compensation method suitable for new energy and pumped storage combined power generation. The method comprises the steps of: calculating the total system profits of a power generation system according to a bundled electricity price and on-grid electricity price of each energy; calculating system pure profits according to the total profits of the system and a pre-obtained feasibility fund of an adjustment power supply project; calculating the compensation electricity price of profitable power supply according to the system pure profits and a preset distribution weight; and performing secondary distribution compensation on the adjustment power supply by using a secondary compensation mechanism according to the gain relationship of the profitable power supply to the adjustment power supply. According to the method, power generation items are firstly distributed according to the pure profits, and each power generation item provides rewards to pumped storage through gain effects of service item-pumped storage on different indexes of each power generation item, so that the pure profits of each power generation item subjected to secondary distribution is still more than the pure profits of independent power generation; the problem of unreasonable distribution caused by a capacity distribution strategy and an equipartition strategy is solved, and the income distribution process is more reasonable.

Description

technical field [0001] The invention relates to the technical field of combined power generation and income distribution, and more specifically relates to a revenue compensation method suitable for new energy and pumped-storage combined power generation. Background technique [0002] At present, the proportion of wind power and photovoltaic power generation continues to increase. In this process, although the total power generation has increased, the output of wind power and photovoltaic power generation has volatility, intermittent, randomness, etc., and its instability will cause the entire The frequency of the grid fluctuates. At present, chemical energy storage and pumped energy storage are often used to coordinate the power generation of new energy. The pumped storage power station is recognized as one of the ideal peak-shaving power sources. Its main features are rapid start-stop, fast loading and unloading, flexible and reliable operation, and can not only cut peaks ...
