Research on the High Proportion Consumption Mechanism of New Energy to Promote the Green and Low-Carbon Transformation of Energy

For the background that the traditional units have been unable to meet the frequency modulation requirements of the power system with high renewable energy permeability, the energy storage technology with accurate and fast power tracking performance has been widely concerned in the current frequency modulation research field. The fast response and accurate power command tracking characteristics of the energy storage technology make it more suitable than the traditional synchronous unit to participate in the power grid frequency modulation control with high climbing rate and low power demand, which can better meet the system frequency modulation index. it can also significantly reduce the rotating reserve capacity of the power grid. According to the technical parameters of all kinds of energy storage which are widely used at present, it can be known that all types of energy storage can meet the requirements of power climbing rate and response time of frequency modulation in power grid. However, considering that the installation and maintenance cost of energy storage is still at a high level, the application of energy storage alone in FM is still restricted by its high configuration cost, which economically limits its participation in power FM control applications. Therefore, in order to face all kinds of problems existing in the power system with high proportion of new energy, the specific application strategies of energy storage are put forward.
