Abstract:
Pakistan has recently reshaped its Policy for promoting further Renewable in its energy mix, which is currently dominated by thermal Plants. Among renewable, Solar Photovoltaic (PV) is most prominent because of significant decrease in solar prices over the past few years. Therefore, that gives us more flexibility for a paradigm shift from diesel generation to Solar PV in term of cost effectiveness and low carbon emission. The concept of centralized generation is now changing with the integration of renewable generation on the distribution side. Solar energy being most prominent renewable resources are serving as an alternate and reliable power supply on the consumer side. But this integration may affect the line parameters on the distribution side. In this project an IEEE 13 radial bus system is simulated in MATLAB. The system consists of 11 KV, 1 KVA feeder which is stepped down to 120 volts to feed 750-watt load. For the modelling of distribution line, series inductor and resistance are used. The lumped load used in the simulation is of resistive and inductive nature. The load flow bus is used to analyse different distribution parameters of the network. For the voltage stability, Static VAR compensator is also integrated in the system. A prototype is developed in which 13-bus parameters are lumped together to form a 3-bus system. The prototype gives approximate results which will help us to analyse overall system behaviour of the system. Today the society depends on secure supply of energy. This thesis proposed a comprehensive analysis on voltage regulation of PV integrated network with using fixed capacitor banks, additionally it also addresses the issue of over loading on conventional and nonconventional voltage regulation scheme for different penetration level.
