Methodology And Operation Of Dc Micro Grid For Wind And Solar Power Integration

Abstract

Distributed generators (DGs) focused on renewable energy play a dominant role in the production of electricity, with the increase in global warming. With the use of fuel cells and microturbines, distributed generation based on wind, solar energy, biomass, mini-hydro will give significant momentum in the near future. Advantages such as environmental friendliness, expandability and versatility have made distributed generation an attractive option to manage modern electrical grids, powered by various renewable and non-conventional micro-sources. A microgrid consists of a load cluster and distributed generators operating as a single controllable unit Microgrid can run in conjunction with or separately from the main power grid as an integrated energy delivery system. The idea of microgrid implements minimizing multiple reverse transitions in an individual AC and DC grid as well as promoting connections to intermittent renewable AC and DC sources and loads to power systems. The interconnection of DGs to the utility / grid -electronic power converters has raised concerns about safe operation and equipment safety. The microgrid can be configured for the customer to meet their specific requirements; such as enhancing local performance, minimizing feeder losses, supporting local voltages, increasing efficiency through the use of waste heat, tension reduction correction and continuous power supply. The output of the hybrid AC / DC microgrid network in the grid connected mode is evaluated in the current work. For the production of microgrid, photovoltaic network, wind turbine generator and battery are used here. To order to properly align the AC subgrid to DC subgrid, control mechanisms are also introduced for the converters. The findings are obtained from the framework of MATLAB / SIMULINK.
