본 연구는 해양 시설물용 태양광-풍력 하이브리드 발전 전력 제어 시스템에 대한 연구를 수행하였다. 해양시설물은 대부분 태양광 기반의 발전 시스템으로 되어 있다. 이러한 태양광 발전 시스템은 흐른 날씨에는 전력 생산량이 감소한다. 이러한 발전 특성을 보완하기 위해 태양광과 풍력을 연계하는 시스템을 연구 하였다. LabVIEW를 이용하여 태양광과 풍력 발전 시스템을 시뮬레이션 하였다. 전력 특성을 반영하여 벅컨버터를 이용한 발전 전력 시스템을 개발하였다. 이를 실험을 통하여 풍력과 태양광 전력을 안정적인 충전을 수행하였다.

As a first step to develop the hybrid power generation system, on this study, the time-variable resources of wind and solar radiation of Yeongdo, Busan, Korea had been measured during June and July 2013. And the quantity of generated wind power and solar photovoltaic had also been measured during the same period. It is found out that the wind mainly flew from southwest at the average speed of 2 m/s during 2 months. And it is clear that, because of the low wind velocity, the wind quality to generate the power seems not enough at this area. Meanwhile solar radiation was measured every daytime (6:00~19:00) and the peak solar radiation occurred around 12:00~14:00. And it is clear that the time-based variations of quantity of generated power were proportional to the variations of these resources, respectively. As a proposal, these 2 natural energies can be combined as resources of a hybrid system, because these 2 patterns are not overlapped so much on time base.

A Buoyant Hybrid Power Generation System (BHPGS) described in this paper, is a conceptual approach to a hybrid solar-wind power generation in the near sea. The primary purpose of the BHPGS is given to improve utilization of solar cell modules. Main components of the BHPGS include a solar cell module, buoyant object, power generator, and support assembly including weight. Components such a generator controller, DC/AC converter, etc., are not configured in the current BHPGS because they can easily be purchased as a commercial-off-the-shelf product. In addition, some of the BHPGS applications are discussed.

This paper reports the performance of Wind-PV(Photovoltaic) hybrid system. The output power of PV is affected by the environmental factors such as solar radiation and cell temperature. Also, the output power of wind system is generated with wind power. Integration of Wind and PV resources, which are generally complementary, usually reduce the capacity of the battery. This paper includes discussion on system reliability, power quality and effects of the randomness of the wind and the solar radiation on system design.

Recently, the use of renewable energy has been increasing to achieve carbon neutrality. The concept of a zero-energy building is also attracting attention. In this study, a preliminary study was conducted to analyze the feasibility of a hybrid wind and solar power generation system between buildings that utilize the building wind generated by the Venturi effect. For this purpose, the wind speed and sunshine hours were monitored in the area where the building wind blows by the Venturi effect, and the power generation depending on system types, areas, and season was estimated. Consequently, the wind power generation system showed a larger amount of power per area than solar power. The wind power systems can generate larger power if wind power blades are installed along the height of the building. As a preliminary study, this study verified the feasibility of the system utilizing building wind and suggested follow-up studies.

Photovoltaic energy and wind energy are highly dependent on the season, time and extremely intermittent energy sources. Because of these reasons, in view of the reliability the photovoltaic and the wind power generation system have many problems(energy conversion, energy storage, load control etc.) comparing with conventional power plant. In order to solve these existing problems, hybrid generation system composed of photovoltaic(500W) and wind power system(400W) was suggested. But, hybrid generation system cannot always generate stable output due to the varying weather condition. So, the auxiliary power compensation unit that uses elastic energy of spiral spring was added to hybrid generation system for the present study. It was partly confirmed that hybrid generation system was generated a stable outputs by spiral spring was continuously provided to load.

The objective of this research is to investigate usage of 3KW photovoltaic-wind power hybrid generation system composed of 500W solar power generator and 400W wind power generator in a parallel circuit. In addition, solar radiation meter and wind monitor have been installed into each generation system to obtain the practical operating data that monitored in monthly, daily and hourly. These data that are independent to weather change and location would provide adequate generation output on average and cope with emergency situation in generation system In conclusion, based on this study, it could be considered for 3KW combined generation system to be gradually propagated to houses and small-size public facilities.

태양광 풍력 하이브리드(Hybrid) 발전 시스템에서는 발전의 주 인자인 태양의 일조량과 바람의 세기 등이 환경적 요인으로 적절하지 못할 경우 충방전 성능의 한계를 가지고 있는 에너지 저장장치인 배터리를 충전하는데 어려움이 발생한다. PCS(power conditioning system)는 태양광 풍력 발전 시스템 운용에 필수적인데 기존의 대부분의 PCS는 중대형 중심이어서 소형 발전에 적합하지 않아 효율이 높고 안정적인 동작을 하는 소형 발전용 PCS 개발이 절실히 요구된다. 본 논문에서는 이러한 문제들을 해결하면서 상용(한전)전력과의 계통연계 및 독립 운영이 가능하고 배터리의 장수명화와 안정화가 가능한 1kW급 하이브리드 CC/CV(constant current/constant voltage)기능을 갖는 PCS를 설계하고 시제품으로 구현하여 그 성능을 검증한다.

Recently, the increased interest in environmental issues has led to extensive research for development of green energy generation systems. However, only one type of generation system may not be sufficient for stand-alone mode because it cannot cope with the irregularity of weather condition. A hybrid generation system is able to make up for the weakness of each system. In this paper, a stand-alone hybrid wind/PV system is developed that can guarantee the stable energy supply. The system is suitable for power supply under 50W, and a vertical savonius type of blade was designed and applied for the wind generation system.
