Control Strategy and Simulation of Power Security Supply System Based on Hybrid Energy Storage
摘要
Abstract
To provide reliable power supply for important load and reduce the influence of impact load on grid,a power security supply system based on super capacitor and battery is proposed. Firstly,the topological structure of this system is presented,then its mathematical model is built. Secondly,the coordination control strategy for the system is studied in detail. Through detecting the status of grid,the load capacity,and the state of charge(SOC)of hybrid energy storage (HES),the operating modes of converters can be determined comprehensively. Moreover,the control strategies for di?rect current converters and voltage source converter(VSC)are put forward according to the control goals of different op?erating modes. Finally,several typical operating conditions of the novel system are simulated in Matlab and results veri?fy its functions and control strategies.关键词
