In the current energy scenario, renewable energy resources are the key alternative to fossil fuels in order to meet the ever--increasing demands across the world. Renewable energy system plays a vital role for the reliability of the power system. Due to the intermittent and random probability distribution nature of each renewable sources Hybrid systems are coming into existence. Use of hybrid systems is an effective solution to energy storage and Power quality features. As the technologies are developed to operate the renewable energy source as grid-connected rather than islanding mode energy storage system gain a more attention in decentralized power system. Micro grid energy management systems are key components for ensuring the stable and economic operation. By using different storage techniques such as Battery, Super capacitor, Ultra capacitor, Multilevel inverter and Fuzzy logic rules these power management systems are popular in integrated operated renewable systems. The energy storage systems are most basic and popular amongst all the distributed energy sources of energy storage systems. However, the management and quality of hybrid energy systems based micro grids are difficult. © TJPRC Pvt. Ltd.
