Development And Application Of DC Power Supply Based On Hybrid Storage System

As a new kind of energy storage component,supercapacitors have fast response, high charge-discharge effciency,and there are types of commodities on sale which speedup assemble and facilitate to enlarge energy storage capacity,therefore the supercapacitor is considered the most promising energy storage device.Supercapacitor dc energy storage system is the key device of the supercapacitor energy storage system. It plays an important role on improving efficiency and reliability of supercapacitor energy storage system.In conclusion,based on some important aspects of Supercapacitor energy storage unit application and design,the equivalent model of directly paralleled supercapacitor/Battery hybrid was set up and the performance and its influence factors were analyzed quantificationally with pulsant load as an example.As supercapacitor use in dc power supply,design feedforward plus feedback to regulate the system operation,MATLAB simulation results presented to show the feasibility,which have theory and practical meanings to provide optional scheme to the project applications.
