Innovative Design and Application of a Large-Scale Electrochemical Energy Storage Power Station
摘要
Abstract
To achieve the "dual carbon" goal,energy storage power plants have become an important component in the development of a new type of power system. This paper proposes a design innovation and empirical application for a large energy-storage power station. A panoramic operational monitoring system for energy storage power plants was designed based on a modular integrated design scheme. A fast coordinated control technology for energy storage power plants based on the Ethercat technique was proposed,which balances the power distribution consistency of multimachine parallel systems and improves the dynamic response performance of energy storage power plants. Considering the control switching modes and SOC states of energy storage power plants,adaptive virtual inertia control and primary frequency modulation control were designed to obtain active support capabilities. The proposed scheme was empirically demonstrated at the Xiapu Energy Storage Power Station in Fujian Province. Compared with traditional schemes,the proposed scheme has better multi-PCS synchronization,faster overall station response speed,and can provide active inertial support and frequency modulation services for the power grid.关键词
