Design and Modeling of Hybrid DC/AC Microgrid With Manifold Renewable Energy Sources

Abstract

The increased demand and depletion of the fossil fuels for power generation led to the need for extracting power from the renewable energy resources (RERs). The microgrids (MGs) are designed with the help of effective power extracted from renewable sources such as solar, wind, tidal, and geothermal. The advent of DC MGs overcomes the conventional AC grids. The hybridization of the AC and DC MGs will provide more advantages for various levels of consumers. This article proposes the design and modeling of a hybrid DC/AC MG with the efficient use of RERs and it can reduce numerous power conversions. The solar energy is extracted through photovoltaic (PV) panels meritoriously using interval type 2 fuzzy logic technique as the maximum power point tracking algorithm. The AC grid is designed using wind energy source and tidal energy. The permanent magnet synchronous generator is used as the wind turbine. Various control mechanisms are employed in order to extract maximum power from the wind and tidal waves at varying conditions. These generated powers can supply the load and are connected to the utility grid. These are executed with the aid of MATLAB/SIMULINK software.
