태양광 발전소에 대한 성능을 평가하기 위해서는 IEC 61724-1에 적합한 계측장치를 설치하고 데이터를 수집하여 평가하는 것이 일반적인 방법이다. 본 논문에서는 태양광발전소 현장에서 DC 어레이 성능을 평가하기 위한 방법을 제시하였다. 측정 일사량과 같은 환경정보 값과 태양광 DC 어레이 전압-전류 특성 곡선을 이용해 일사량에 따른 출력모델 식을 도출하였다. 도출된 모델 식은 태양전지 셀의 종류나 버스바에 따라서 차이가 발생되므로 기존의 태양전지 셀 등가회로 수식을 반영한 시뮬레이션 모델식이 적절히 변경되어야 함을 실험을 통해 검증하였다. 주기적인 진단 평가를 실시하지 않는 국내외 태양광 발전소는 성능저하가 발생된 상태로 운전되는 경우가 다수 일 것이다. 대부분의 관제모니터링을 시스템은 미쓰매칭 손실 평가분석이 불가능하며 운전상태 모니터링 하는 시스템이 대부분이다. 이에 태양광 발전소의 효율적 운영을 위해서는 현장진단 장치를 이용한 주기적 성능진단 평가나 발전소 데이터의 손실평가 분석 기술의 개발이 필요할 것이다.

기존의 태양광발전소 사업자들은 발전소에 대한 정보를 알고 싶어도 실시간 정보가 제공되지 않아서 불편했다. 발전소 유지보수 업체는 언제 어디서나 태양광 발전 시스템을 확인 점검할 수 있는 원격 관리시스템을 필요로 한다. 또한, 간단한 제어로 태양광 발전소를 정상 동작 시킬 수 있는 기능의 원격 제어가 요구된다. 본 논문에서는 스마트폰 기반의 태양광발전소 원격관리시스템 개발을 통해 태양광 발전시스템의 유지보수 편의성 향상에 기여하고자 한다.

In this paper, the relationship between the angle control of the panel contributing to the optimum power generation efficiency of the solar power plant is investigated. For a total of eight months, one of the two plants with the same equipment configuration changed their angles every three months and the other plants did not change their angle. In this study, we propose a model that can maximize the power generation efficiency by comparing and analyzing the difference of power generation between stationary solar power station and stationary solar power station through simulation.

The rapid spread and various design of solar power plants, development, construction, maintenance technology and business coexist variety and price decline and the recent solar power plants built since the early 2010 despite the decline in the power generation unit main equipment Construction of power plants to stabilize the technology has been continuously promoted. Recently, built in the form of a solar power plant to the construction and leasing the roof and upper structure to replace the limited ground space is increasing. Factory roof, studies such as warehouse and logistics center leased space in the roof installed solar plant status and skills, conducted a study to review and analyze the economy.

현대중공업은 2009년 충북 음성에 500kW급 태양광 발전소를 건설하여 태양광 인버터 개발품에 대한 실증시험을 진행하고 있다. 본 연구의 목적은 태양광 발전소내에서의 실제 발전 전력을 분석하여 고품질의 전력을 발전하는 제품을 만들고자 하는 데 있다. 전력의 품질은 태양광 인버터의 제어특성 뿐만 아니라 일사량이나, 구름의 움직임, 온도 그리고, 계통의 부하에 따라 변화하므로 발전량 전영역에서 고품질의 전력을 생산하는 것이 매우 어렵다. 본 연구에서는 전력의 품질을 확인하기 위하여 역률 및 고조파를 측정하여 나타내었다. 연구 결과 저전력에서의 역률 및 고조파의 큰 변화를 확인할 수 있다.

Recently the construction of solar plant showed a steady growth in influence of renewable energy policy. It is very important to determine the optimal location and aspect of solar panel using analyzed data of solar radiation to solar plant area beforehand. This study analyzed solar radiation in solar plant area using DEM acquired from UAV geospatial information. Mean solar radiation of 2017 was calculated as $1,474,466W/m^2$ and total solar radiation of 2017 considering solar plant area showed $33,639MW/m^2$ on analyzed result. It is important to analyze monthly solar radiation in aspect of maintenance works of solar plant. Monthly solar radiation of May to July was calculated over $160,000W/m^2$ and that of January to February and November to December showed under $80,000W/m^2$ in monthly solar radiation analysis of solar plant area. Also this study compared with solar radiation being calculated from UAV geospatial information and that of National Institute of Meteorological Sciences. And mean solar radiation of study area showed a little high in comparison with whole country data of National Institute of Meteorological Sciences, because the 93.7% of study area was composed of south aspect. Therefore this study can be applied to calculate solar radiation in new developed solar plant area very quickly using UAV.

We analyzed the system efficiency of small solar power plants with 80% of total solar power plants. The data of the solar power plant with installed capacity of 100kW was collected and the correlation of the ESS efficiency according to the capacity of the PCS and the battery of each power plant was deduced. As a result, the higher the C-rate value affecting the discharge rate of the battery, The discharge efficiency of the plasma display panel is increased.
