Abstract
ABSTRACT
Renewable sources of energy have become common alternative sources of electrical energy and Theoretical Studies of photoelectric (PV), energy systems linked to the electric grid has been proposed by several researchers. PV has been greatly improved in the last few years. In addition, the biggest problem with the PV energy system is how to get the utmost value out of the energy under a changing solar radiation. To take full power of the PV array output energy dependent on the change in solar radiation, maximum power point tracking (MPPT) techniques are used in the PV systems to overcome these issues, this thesis proposes. Performance analysis of grid connected photovoltaic systems and using the results to prepare a training program for the students at the faculty of industrial. This done through the following steps:
The first part of the thesis describes. The theoretical application of MPPT technology for grid connected PV system. This done to track maximum energy under rapidly changing weather conditions in two states of PV radiation changes the change of solar radiation in ramp profile and the width under change step. This thesis presents is the MPPT of a grid-connected PV system as a simulation and experimentally to track the speed of PV radiation change in different operating conditions. A comparison between the two methods IC and P&O for MPPT by showing the results for the power, current and voltage of the source and the grid.
The Second part of the thesis describes comparative analysis of grid connected PV system by using PI and sliding mode control (SMC) under ramp and random changes of solar radiation. Simulation results show the feasibility and power of control systems. Finally, a simulation result was compared PI with SMC results for energy, current, and voltage coming out of the PV array as well as the electrical grid.
the third part of the thesis describes. design a training program based on constructive education, develop the concepts and skills of graduates of the College of Technology and Education in the Department of Electrical Technology, and measure its effectiveness. The results of the implementation of the program showed the effectiveness of the proposed program and the development of the trainee’s skills.
Finally, an experimental work of a PV grid connected system, is implemented in the laboratory (Smart Systems Labs). The experimental study focuses on analyzing the
performance of a PV grid connected system during variation of the environmental conditions.
