Electrical energy is one of the most important component in the development of any society. Electrical energy is primarily generated from fossil fuels,  nuclear power or hydro but an increasing gap between demand and generation is leading is to find an alternative energy sources that produce clean energy and meet our increasing needs while maintaining the secure and reliable operation of power system. Presently Pakistan is facing extreme energy crisis and the situation is even worse in remote areas that are deprived from basic facility of electrical energy. These areas are normally gifted from natural resources that can play a key role in overcoming this problem. Run on River hydro generating units, solar Photovoltaic cells and Biomass generating units are able to generate clean electrical energy and meet the local demands; however, it is important that the frequency and voltage of that area is maintained within in the specified for the secure operation of power system. The voltage control plays important role in stable and reliable power supply. This research project will model a standalone micro grid where electrical energy will be generated from alternative sources of energy that are renewable i.e. hydro, solar irradiations and biomass resources, and then will employ specific technique for voltage control. This study will analyze the system behavior in different seasons when the load demand varies.
