Abstract
One major solution to the ever-increasing energy demand comes from the complementary use of the renewable energy sources. Among today’s renewable energy choices, solar electric power has emerged as the market’s most viable option. Renewable energy may not be able to completely replace existing energy conversion systems, but it is important to recognize the continuing depletion of fossil fuels and the problems created by their use during the past two centuries. Depending on the country and the geographical location, appropriate renewable energy technologies should be selected in order to meet the required energy demand.
The main objective of this thesis is to study the operation of PV power system when feeding different applications, and to evaluate a method to get the optimum operation of the load feed by PV systems for Kuwait site.
A mathematical model represents both PV solar cell and maximum power point tracker is evaluated and Matlab codes represent the whole PV system are then created and presented.
The thesis focused on PV-water pumping as one of the most promising areas in photovoltaic applications. Photovoltaic powered water pumping systems require only that there be enough sunshine and a source of water which is adequate for many developing countries. The thesis presents a new design and simulation of a simple but efficient photovoltaic water pumping system using Matlab program. The maximum power point tracker (MPPT) is designed and simulated using actual irradiance data. The DC pump motor is modeled using Simulink and the model is then transferred into Matlab, so that the whole system is simulated in Matlab environment. The algorithms are tested with actual irradiance data in Kuwait.
The thesis also, investigates the operation of direct coupled PV-water pump in Kuwait. The PV water pumping system connected to MPPT with different efficiencies is tested. Several tests were performed to achieve the goal of maximizing the overall water lifted in a certain period of time. The different factors affecting the total water pumped are examined. These factors include: the PV panel type, series-parallel connection of the PV panel, types of tracking system, water head, and pump type.
