The fossil fuel prices are increasing continuously and the electricity generation from these resources is expensive along with the carbon emissions. The developed countries are taking steps to shift towards clean and green energy resources but due to lack of budget, poor countries are still striving to get reliable and clean energy. Therefore, the design & analysis of a low-cost hybrid power system has been carried out in this thesis for a Pakistani industrial unit. The sizing ie capacities of power resources which gave minimum per unit cost along with the capital cost are calculated using the HOMER PRO. In HOMER, three cases have been discussed including offgrid and grid-tied, the most feasible case needs an 8283 kW PV array to fulfill the demand of the plant with a 76 % load factor. This most economical case grants 0.102 $ per unit of electricity which is the cheapest among all cases. To study the dynamic of the system, the modeling of the designed system has been carried out in MATLAB/Simulink with the help of Simscape blockset. The information is used in designing each parameter of MPPT, Inverter, and LCL filter. The system is tested, and its transient time came out to be 1.5 s and after that it becomes stable. The designed system is tested under load variations and results show that it can deliver or receive the power from the grid in a smooth manner depending upon the PV generation. In addition, an abrupt change in system cloud movement has been observed, the system can handle 300 W/m2 irradiance change while maintaining its frequency and voltage within the permissible limits. For operations purposes, a low-cost monitoring SCADA system has been designed using EMONCMS which is an opensource web view platform. Designed SCADA also acts as a local server and stores the reading locally along with a user-friendly environment. Thesis shows, the designed hybrid power system is economically feasible, reliable, and safe which will help to reduce the carbon emissions along with low-cost electricity.
