Development and use of renewable energy due to environmental problems and depletion of energy affect grid-connected power system around the world. Therefore This paper analyzes the characteristic of gird connected photovoltaic power generation system which it is available to connect the utility. Renewable energy photovoltaic power system has been linked to the system to analyze the impact of photovoltaic system. MATLAB / Simulink program is modeled and analyzed on power quality of a photovoltaic power plant.

Harmonics of the power quality in systems is growing more and more as a modern industrial society process. Among these harmonics, the problem of dangerous situations is generated especially in the whole system when exists high levels of harmonic. In this paper, we analyzed about type of cause for harmonic on the quality measurements and performed simulation for resolving the problem on ther basic types of filters installation before and after.

The photovoltaic power generation is one of the most suitable energy sources in the worldwide as a new and renewable energies for the fossil fuels shortage and global warming. The PV system needs a large area, appropriate module arrangement and sufficient solar radiation to get maximum power generation. In this paper, the optimum installation area size for an inclined fixation photovoltaic system was presented by calculating and simulating the optimum angle of solar radiation and arrangement of PV modules in the economic aspects pursuing the user's maximum profits.

Power systems becomes more highvoltage and high capacity recently. Power system caused by the accident of insulation breakdown. Excellent power cable is used due to advances in technology, but old cable and damage cable causes a power failure. This paper analyzed partial discharge using pattern analysis method of power cable. The simulation of partial discharge of power cable with defects was analyzed using pattern recognition methods.
