Abstract:

A 2 kW Hybrid Microgrid with PV, Wind Turbine and BESS: Design, Modeling and Simulation. In this paper, design, modeling and simulation of a 2 kW hybrid renewable energy microgrid having solar PV, wind turbine generation and BESS are presented. Perturb and observe (P&O) MPPT algorithm is adopted for PV subsystem whereas dynamic wind speed model is used for wind turbine. In this model, a Fuzzy Logic Controller (FLC) controls the power flow between battery, load, grid, and renewable sources in real time. The DC link is connected to AC grid through a three-phase inverter and transformer. Simulation results in MATLAB/Simulink indicate that the proposed system can supply steady 2 kW load with proper battery charge/discharge control and it doesn\'t need a lot of grid power. The proposed system can find applications in rural electrification, isolated communities, and smart grid installations.
