As the new energy installed capacity in China continues to increase,the pressure on new energy consumption is also increasing.As a green,low-carbon,and flexible regulating power source with the most mature technology,optimal economy,largest scale development conditions and longest life cycle,pumped storage plays an important role in new energy consumption.Pumped storage is developing rapidly,while the operation intensity of units also tends to increase.An accurate evaluation of the unit operation intensity can enhance the understanding of pumped storage unit operation status,guide the unit operation and maintenance,and provide a strong basis for the unit condition maintenance.However,at present,for pumped storage unit operation intensity,the evaluation still relies on empirical judgment and there is no mature evaluation method.This paper studies the evaluation methods for pumped storage unit operation intensity based on analytic hierarchy process and entropy weight method.Actual operation data are used to realize real-time operation intensity evaluation of multiple units,so as to understand the magnitude of unit operation intensity more intuitively,and effectively ensure the safe and stable operation of pumped storage units.These methods have broad prospects for promotion and application.
