Research on control strategies for hybrid energy storage system in stand-alone photovoltaic system
摘要
Abstract
Control strategies for hybrid energy storage system in stand-alone photovoltaic system were studied.A novel strategy based on pattem recognition and humanoid intelligence control was proposed.The strategy required that the DC-DC connected to batteries had constant current output and the DC-DC connected to super capacitor had constant voltage output.By observing voltage across super capacitor,the current pattern was recognized,then rules were used to conclude the limit value of change rate and change value of battery current in order to make the battery current smooth and change with the load.Theoretical analysis and experiments verify that the strategy gives priority to super capacitor to absorb power change of the load,and make the battery current smooth and change with the load.The strategy implemented control purposes of hybrid energy storage system effectively,and was easy to carry out and had high performance price ratio.关键词
