Simulation Analysis of Stability Operation of Hunan Power Grid Supported by Energy Storage

Abstract

Energy security is a widespread and strategic issue related to national economic and social development. With the proposal of the "dual carbon" goal, the energy storage industry and energy storage technology, as the core support for the development of new energy, can provide the power grid with objective and adjustable resources, which can effectively alleviate the lack of flexibility of the AC and DC power grid and ensure its safety and stability. In this paper, an electromechanical transient model of the energy storage power station adapted to the working conditions of the Hunan power grid is constructed. The effect of different reactive power equipment and different control strategies of the energy storage system on the reactive power support of the system is simulated and analyzed The application value of energy storage in the power grid is evaluated.
