Design and Modelling of Multilevel Inverter for Micro Wind Energy Generation System

Renewable energy sources are used extensively in a wide variety of applications as it is available in abundance, and also pollution free. This paper discusses the wind energy system connected to the micro grid system used for small scale operations. Wind Energy Systems are connected to the grid through a conventional two level inverter which results in high value of THD and harmonics in current. This problem can be overcome by multilevel converter with different switching strategies. The simulation is done in MATLAB tool and comparison is made to prove the results with hybrid multilevel inverter provide low value of THD. Distribution of Reusable Energy based power generation plants, their incorporation into the already existing utility grid will result to the concept of Micro grid and Smart grid system which can be obtained from the Simulation and investigation of a standalone DC Micro grid System. Proposed system utilizes wind Energy system as the main source of the grid and battery as the Energy Storage System (ESS). Usage of renewable energy sources for electrical application will meaningfully lower the fuel consumption for the generation of electrical power that in turn automatically reduces the emissions of greenhouse toxic gas. Along with wind energy system, this paper proposes a design that joins the doubly taken care of enlistment generator (DFIG) based breeze turbine and Solid State Transformer activity. Because of the breeze power being a wild asset, different issues in regards to control quality and security issues are created. The Solid State Transformer (SST) has been discovered to be helpful in mix of various dispersed fuel sources just as wind power in the appropriation matrix with different functionalities.
