Abstract: The renewable energy resources (RERs) are a good way to supply the electricity for some remote places that are hard to connect to the power grid and some areas where storms and other catastrophic events cause long-term power outages from power grid. What is more, in order to control the global warming and reduce the pollutant emissions, changing fuel power generation to renewable power generation is significant.
This paper discusses the modelling, control and analysis of grid connected wind energy based power generation system for fulfilling the electricity demands load. Battery energy storage system is employed for the backup source as wind is intermittent and unpredictable in nature. As the variations in wind speed and connected load, the power generation and consumption is continuously changing. To counter these variations a control scheme is developed using grid-side controller, generator-side controller and pitch angle controller. The DC link voltage is maintained in specified limits to maintain the active power balance between supply and consumption. Furthermore, a DC-AC converter and its controller is used to maintain the AC side voltage and frequency in limits for proper synchronism with the grid.
The proposed system is modelled and implemented in MATLAB environment. Various cases are simulated based upon the wind speed availability and load requirements. The results shows the efficacy of the proposed system
