Renewable energy-based distributed generators (DGs) presents an imperative role in electricity production, with the increase in global warming. Distributed generation based on wind, solar energy, biomass, mini-hydro, along with the use of fuel cells and micro-turbines, will give notable energy shortly. Advantages like environmental friendliness, expandability, and adaptability have made distributed generation powered by several renewable and non conventional micro sources, an attractive option for configuring modern electrical grids. A micro-grid consists of a cluster of loads and distributed generators that operate as a single controllable system. As an integrated energy delivery system, the micro-grid can run in parallel with or isolated from the primary power grid. The micro grid concept proposes the reduction of multiple reverse conversions in an individual AC or DC grid and also expedites connections to variable renewable AC and DC sources and loads to power systems. The inter-connection of DGs to the utility/grid concluded power electronic converters have risen concerned about safe operation and protection of pieces of equipment. To the customer, the micro grid can be premeditated to meet their particular requirements, such as enhancement of local reliability, reduction of feeder losses, local voltages support, increased efficiency through the use of waste heat, improvement of voltage sag, or uninterruptible power supply. In the present scenario, the performance of a hybrid AC/DC micro grid system is analyzed in the grid-tied mode. Here photo voltaic system, wind turbine generator, and battery are used for the development of micro grid. Also, control tools are implemented for the converters to coordinate the AC sub-grid to DC sub-grid properly.
