Several renewable sources are utilized with parallel operation with sharing of load depending on dynamic changes in the environmental parameters. Compared to other renewable energy sources, wind is the second largest and highest energy sharing renewable energy source. However, the initial construction cost is high as compared to other renewable sources. After wind systems, solar power generation (PVA) are considered to be most promising renewable sources followed by fuel cell stack. In this paper, we have modeled a standalone renewable source microgrid with multiple sources, viz. wind power generation using PMSG, PVA and battery storage system. Performance of each source is done with respect to variation of load and variation of source parameters such as wind speed, irradiation, temperature and state of charge of the battery. For backup power supply to the load during failure of the renewable sources a battery storage source is provided. This storage source (battery) can be charged when excess power is generated from the solar (PVA) and wind power generation system. Analysis on each sources with dynamic changes of parameters are produced with explanatory graphical representations is done using ‘powergui’ block available in MATLAB Simulink software.
