Research overview of optimization of multi-source and energy Storage in microgrid

Multiple power modes and energy storage devices is distributed in microgrid and use of wind and solar energy to bring volatility and intermittent, in order to provide a stable power, micro-grid energy storage device must be researched. In order to improve power quality, reduce storage configuration capacity, improve the economic system, We have a research on the optimization of variety of micro-grid energy configuration and economy operation. This paper analyzes their differences and characteristics of energy storage devices and can conclude that complex microgrid energy storage device is reasonable storage mode. Next, the paper have a description on mathematical models of economic and environmental benefits and restrictions to maintain the stability of the micogrid. Finally, our paper analyze their strengths and weaknesses as well as summary of the algorithms used to solve these models.
