An overview of micro-grid architecture with hybrid storage elements and its control

This paper discusses the role of hybrid energy storage systems in future grids to improve the penetration of renewable energy sources. The storage systems are essential in the future grids to improve the power quality and maintain the grid stability under high penetration of renewable sources. The use of more than one type of energy storage elements in the grids with different response times will help in improving the efficiency and reliability of the storage systems. The different control strategies for load sharing among these storage devices are discussed in this paper.
