Research On Control Strategy Of Islanded Micro Grid Power Generation System

With the increasing depletion of global fossil fuel, greenhouse growing, energy issuesand more attention each country. Into the21st century, high utilization of renewable energy ischaracterized by the micro-grid is the industry that is a new direction for grid development,micro-grid or grid access large island operation to become a trend in the development of thegrid. However, adding micro-grid power will produce large effects, such as micro-gridcontrol strategy is more complex, if not controlled micro-grid, it will have a huge impact onthe hair grid, so the micro-grid power system control technology research becomes to critical.Firstly, studied the definitions and structure of microgrid; then for the distribution ofresources in Xinjiang, proposed several suitable for the local power supply micro-gridstructure, and analyze its characteristics; then post in MATLAB/simulink platform to buildwind power, photovoltaic, diesel generators and fuel cells, micro-power model, andsimulation analysis; Finally, from the micro-micro-grid power control technology andcontrol technology both for microgrid control strategy analysis and research, and for thepreviously proposed microgrid structure of the simulation analysis control strategy, throughsimulation graphical analysis and research, draw the correct control strategies are available,micro-grid structure used correctly, offers some solutions for the local power supply.
