태양광발전시스템의 최적설계에 의한 효율개선에 관한 연구

Abstract

Photovoltaic system is using the clean and infinite energy source, there is no air pollution, noise and vibration. and PV system operate without fuel convoy, rotation surface, high temperature and high pressure, So it is easy to maintenance, long life cycle, simple installation. Respectively international and domestic PV market growth over 30% and 40% every year. Photovoltaic power systems convert sunlight directly into electricity. A residential PV power system enables a homeowner to generate some or all of their daily electrical energy demand on their own roof, exchanging daytime excess power for future energy needs While compare preexisted generation of electric power method with PV system, PV system is more expensive, lower solar energy density, convert efficiency and depend on the weather and natural environment. Both of small size residental PV generation and large scale power generation plant, as distribution power source cut necessary for the peak power is increase, through the various government volunteer system PV system popularization business tried to promoted. So, through this paper sets out key criteria that describe a quality system and key design and installation consideration that should be met to achieve this goal. In the present, there is not insured reliability of performance and installation standards. PV system design standards need for smoothly material supply and optimal performance. In this paper, It was suggested that new installation standards for PV system setup and various simulation was performed. With according to proposed method, designed for the PV system and investigated through the simulation practically. It was applied to the 3 phases 10kW, grid connected PV system and demonstrated examination in the field. Solar array characteristics, inverter characteristics, system efficiency, performance and stability of system were considered. Proposed optimal design method was studied through the characteristics of demonstration drive analysis.
