Abstract
For the world problem which is the energy problem; renewable energy resources are being utilized in nowadays projects. from the applicable resources in Egypt are the wind and the solar systems. Due to the high solar irradiance in Egypt, the solar systems have the privilege. The solar systems are categorized into two; the solar thermal systems and the photovoltaic systems. The solar thermal transfers the sun-heat, while the photovoltaic transfers the sun-light.
Hence, the aim of this thesis is to generally investigate the solar energy systems, and to define the most efficient and of best benefit system for the location of Egypt, in order to model it and study its performance. from the search, the CPV system proved its efficiency, financial comparability with photovoltaic systems and also the best land utilization. So, the CPV is modeled in the Matlab. The main concern was to simulate the CPV system electrically and to build up DC to AC conversion system to study the performance of CPV in normal case and under different types of fault and sudden load. The electric system is CPV, which is connected to an inverter with LC filter; this system is connected in parallel with the network for a certain period of time, and then the network is disconnected and only the CPV system is supplying the load completely. In addition, PV system is modeled to compare its performance with the CPV system.
