태양광 발전설비에서 태양광 셀의 출력전력을 최대로 부하에 전달하기 위해 태양광 최대전력추종제어를 한다. 일반적인 태양광 최대전력 추종제어는 태양광 셀의 전압과 전류의 곱인 전력값을 비교하여 최대전력추종제어를 한다. 본 논문에서는 MPPT 컨버터의 출력 파라미터 중 전류만을 센싱하여 태양광 최대전력추종제어를 한다. 또한 태양광 최대 전력추종제어를 통해 최대 출력으로 배터리를 충전하고 허용전류를 초과했을 때에는 전류제어로 충전하도록 설계한다. 이를 통해 Solar Car등과 같은 모터 부하에 적용해 보고자 한다.

최근 화석연료에 대한 에너지의존도가 높아지면서 철도차량분야에서 대체에너지를 도입하기 위한 연구가 이루어지고 있다. 본 논문에서는 지자체를 중심으로 활발하게 진행되거나 검토되고 있는 경량전철 시스템에 대해 대체에너지로 각광받고 있는 태양광 발전시스템에 대한 도입 타당성 검토를 연구하였다. 경량전철 전력설비 계통에 태양광 발전시스템을 연계하고자 했을 때, 검토되어야 할 기술적인 사항 등에 대한 조사하였으며, 특히 태양전지판을 경량전철 노선 벽면에 설치하였을 때 발전량이 확보할 수 있는지에 대한 선행연구를 하였다.

The solar photovoltaic power generator can get more power with the higher solar radiation quantity. However, if the higher solar radiation quantity on cell becomes high temperature, the efficiency of generate will be reduced. To install cooling system for this kind of device can be the way to solve high temperature problem on cell but another problems after install it such as increasing of solar generated quantity problem cost to install cooling system and cost to be maintained cooling system weren't discussed to practical use this system. So the present paper described about effect and commercial business possibility of cooling system. After installing a cooling system the results of experiment about 5.76[%] average annual increasing of solar photovoltaic can expect.

The solar photovoltaic power generator is more important than other renewable energy. Because The solar photovoltaic power generator has been commercialized. So the solar photovoltaic power plants have been constructed. The photovoltaic module lifetime is estimated about 20 year. But The results can not be trusted Because It did not test in the korea. In this paper, We test the maximum power of three modules used 23 years.

Based on the consideration of the hourly patterns of the electricity power consumption, this study predicted the effectiveness of hybrid power generation system, which is composed with wind power generator and photovoltaic generator. And this case study is performed at Konrido, which is a affiliated island of Kyeongsangnam-do. As the results, it is obvious that it is not efficient to cover the whole electricity power consumption only with any single power generating system, because the hourly patterns of electricity power consumption, wind power generation and photovoltaic generation are quite different. And because the wind is being through almost 24 hours, it is also found out that wind power generating system with storage battery is the most efficient combination for this case study.

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.

The following study was conducted to determine the optimal location in terms of efficiency for solar energy facilities, and to propose a policy implications for the orientation of the installments. 92 cases in Jeollanam-do Province were selected. A regression analysis was performed between the average electricity generation time as the dependent variable, and the facility, weather and site conditions as the independent variables. As a result, 5 variables were deemed significant. Larger site areas, closer proximity to rivers, islands, oceans, etc., least south-oriented, higher average wind speed, and facilities in agricultural land use and natural environment conservation land use had the highest efficiency. This study minimized the possibility of secure databases and errors following facility types, and was limited in the number of sites studied, since this was only conducted in Jeollanam-do Province. Nevertheless, these conclusions still offer important policy implications for determining the most optimal location for solar energy facilities.

In this study we investigated the risk of electric shock and the possibility of current flow from the sprayed water when fire took place in a photovoltaic (PV) installed building. The sprayed water was analysed by using a mathematical model, a water spray system for water conductivity was made. With changing the initial water flow rate the water resistance was measured, and compared with the numerically expected value. As the experimental and numerical computing result, we were able to define the requirements that must be considered in the fire of PV systems.
