The generation of small hydropower as compared to other different developed environmental methods produces one of the clean energies. In such manner, various application system development through IT technique is being developed for an advanced small hydropower energy resources data mining. However, existing data analysis of New & Renewable Information System for small hydropower resources application is incomplete therefore it limits expressing these information on the Web. Thus for positive usage of small hydropower resources, a more systematic and precise analysis system should be built. This study seeks to develop a map of the domestic small hydropower resources problems to further improve small hydropower resources, developed through Package Tool which can accurately evaluate a wide range of small hydropower basin in a short period of time. Small hydropower Package Tool was calculated using existing Analysis System small hydropower resources which did not provide diverse capabilities resulting to 840 standard basin classified by A and facility capacity, etc., and to assume a 40% annual capacity, expected annual electricity production was calculated. Small hydropower for the national water system of small hydropower resources potential calculated in terms of resources for the development of small hydropower will be utilized as basic data.

본 연구에서는 북한의 수자원 개발 가능량을 분석 및 평가하였다. 이를 위해 포장수력을 수자원 개발 가능량을 평가하는 지표로 선정해서 분석하였다. 포장수력이란 하천이 보유한 잠재적인 발전 능력에 대한 이론값을 의미하며 수력발전을 통해 개발이 가능한 양을 평가하는 데 활용된다. 포장수력을 계산하기 위해, 북한의 27개 강우 관측소의 강우 데이터를 활용하여 유역별 월평균 및 연평균 강우량을 산정하였다. 이를 활용하여 북한 내 주요 7개 유역에 대해 강우에 의한 이론 포장수력을 산정한 결과, 압록강 유역이 7,562.2천kW로 가장 큰 값을 가지는 것으로 분석되었다. 남한과 북한의 이론 포장수력의 효율 및 이용률의 경우 북한의 최대 효율이 42.3%, 이용률은 36.2%로 남한보다 큰 것으로 나타났다. 북한의 포장수력 이용률은 대동강 유역이 12.3%로 가장 낮았는데, 이곳은 전체인구의 40%이상이 거주하는 지역으로 장래 용수와 전력에 대한 수요가 가장 클 것으로 기대된다. 따라서 대동강유역이 수자원개발사업의 우선순위가 높은 지역일 것으로 추정되었다. 본 연구의 성과는 추후 북한 수자원 개발사업의 추진 및 관련된 연구수행에 있어 기초자료로 활용될 수 있을 것으로 기대된다.

The alarming climate change impacts are demanding the use of renewable energy sources like never before. Hydropower is one of the most cost-effective and environmental friendly energy technology recognized in the world. Big hydropower projects come up with the requirements of huge investment costs along with environmental impacts, whereas small hydropower(SHP) are considered a best solution for the economical source of energy. SHP, basically Run-of-River (RoR) type plants can be sustainable renewable energy sources and given the nature of perennial rivers flowing from steep gradient and rugged topography, feasibility of such plants is equally high in Nepal. The objective of this study is to determine the primary potential sites for the development of RoR type SHP sites using Geo-spatial Information System(GSIS). The use of GSIS enables precise survey of large area within a short period of time. This study has focused on the determination of locations by establishing defined criterions and methodologies and hence have located multiple locations rather than selecting one best location. The approach is applicable for the rapid initial screening of potential locations and results can facilitate detail feasibility study for the technical and economic analysis of SHP in the basin.

In this study, we assessed dependency of small hydropower potentials on the two different runoff such as the estimated runoff based on the rainfall amounts and measured runoff. The hydpropower potentials were evaluated using actural power generations taken from Deoksong, Hanseok, and Socheon small hydropower plants over Han and Nakdong river basins, respectively. As a result of comparing the actual power generation amount with the potential amount based on the rainfall amount and the estimated amount based on the observed flow amount by each small hydroelectric power plant, the degree of latent small hydro energy by the observed flow was confirmed to be high. It is confirmed that the potential hydroelectric power generation rate is estimated to be about average 30%Point higher than the actual generation amount as a result of the measured flow rate rather than using the rainfall amount. Based on this, a method for improving the degree of the actual generation amount is proposed.

This study seeks to develop a map of the domestic small hydropower(SHP) resources to further improve SHP resources, developed through package tool which can accurately evaluate a wide range of SHP basin in a short period of time. GIS-based package tool for SHP resources analysis was calculated using 840 standard basin classified by drainage area and facility capacity, etc., and to assume a 40% annual load factor, expected annual electricity production was calculated. SHP resources potential for the development of SHP will be utilized as basic data.

Small hydropower resources for five major river systems have been studied. The model, which can predict flow duration characteristic of stream, was developed to analyze the variation of inflow caused from rainfall condition. And another model to predict hydrologic performance for small hydropower(SHP) plants is established. Monthly inflow data measured at Andong dam were analyzed. The predicted results from the developed models in this study showed that the data were in good agreement with measured results of long term inflow at Andong dam. It was found that the models developed in this study can be used to predict the available potential and technical potential of SHP sites effectively. Based on the models developed in this study, the hydrologic performance for small hydropower sites located in river systems have been analyzed. The results show that the hydrologic performance characteristics of SHP sites have some difference between the river systems. Especially, the specific design flowrate and specific output of SHP sites located on North Han river and Nakdong river systems have large difference compared with other river systems.

The world began to search for new energy sources with increasing energy demand. Renewable energy sources are as hydropower important for alternative energy. Countries with high hydroelectric potentials continue to work to utilize hydroelectric power plants in the most efficient way. Pumped storage hydropower plants are an important investment to meet the growing energy needs at peak times and to store energy. Although it produces energy in many countries, pumped storage hydropower plants have not begun to be built in Turkey which has high hydroelectric potential. A new era will be opened for energy production in Turkey where a large number of pumped storage hydropower plants projects are in study phase with the construction of pumped storage hydropower plants and first nuclear power plant.

최근 국내에서는 기후변화로 인해 수자원의 안정적인 확보가 위협받고 있으며, 그 대안으로 기존 수공시설물을 활용한 추가 수자원 확보를 추진하고 있다. 그러나, 이를 위한 댐 시설물의 재평가 및 연계운영을 통한 용수공급능력 확보는 대부분 다목적댐 및 용수공급댐을 중심으로 검토되어 발전용댐을 대상으로 한 분석 연구는 상대적으로 미흡하다. 특히 발전용댐의 특성을 고려한 정확한 용수공급능력 산정 기법이 요구되고 있으나, 그에 앞서 수력발전에 목적을 둔 발전용댐의 저류특성을 먼저 파악할 필요가 있다. 본 연구에서는 발전용댐의 저류용량, 저류활동빈도, 용수공급기여도 등의 저류특성을 고려하여 발전용댐의 유형을 구분하는 방안과 판단 기준을 제안하고, 북한강수계 발전용댐을 대상으로 그 적용 결과를 도출하였다. 본 연구 결과는 발전용댐의 정확한 저류특성 파악과 함께, 향후 발전용댐 특성에 적합한 용수공급능력 평가 체계 및 운영방안 마련에 기여할 것으로 기대된다.
