The significant effects of climate change such as the change in monsoons and increase in sea level have made the engineers around the world to explore alternate source to fossil fuels. Unlike the other engineering innovations, this one stands out as the most important due to the threat facing the entire world, and makes it a necessity for future. There are many green and renewable energy sources that can be used to generate electricity and Solar PV (Photo Voltaic) technology is a prominent one. This is due to the abundance of the source - sun light that is available for free and the technical benefits the PV system provides. The problem arises when we try to implement this into the existing traditional power system that is run by a centralized power generator as the PV is generally placed in the customer end i.e. the distribution system as Distributed Generation (DG). One of the main problems in integration of PV DG is that its fluctuating nature makes it a challenge to maintain the system voltage within the standard limit and this may in turn affect the already existing voltage control equipment. This thesis discusses the issues related to the integration of PV into the Distribution System and to different mitigation techniques proposed in the literature. This work proposes a feeder level loss minimization control scheme that uses a possibilistic approach to control the DG output to achieve reactive power support and voltage rise mitigation. The proposed control scheme was tested on IEEE Standard bus system and the results are presented in the chapter 5.
