Abstract
Prices of crude oil are highly volatile. Across the globe, conventional power generation system is facing the problems of gradual depletion of fossil fuel resources, poor energy efficiency and environmental pollution. Global pressure is mounting to reduce green-house gases (GHC). As a part of Kyoto protocol political institutions from EU and UK have agreed to reduce substantially emissions of CO2 to help counter climate change by giving emphasis in the use of non-conventional/renewable energy sources like natural gas, biogas, wind power, solar photovoltaic cells, fuel cells, etc. The possible solution to use these renewables would be to integrate these renewable sources in local level to form local dc distribution system. This paper presents the idea of renewables based dc distribution, which meets the electrical demand of local residential and commercial entities. Higher distribution voltage is selected in-order to expand the grid to commercial level and to provide the possibility of direct connection of offshore wind turbines. Wind power is considered as major power source for the system due to its dominance in the renewable energy market. The detailed MATLAB simulation of 5 mw PMSG based WT with fully rated IGBT inverter is carried using suitable MPPT technique. The failure of controller due to saturation of the actuator is mitigated by employing suitable Anti-windup scheme. Simulation result shows good dynamic performance of the system.File | Dimensione | Formato | |
