  • Most of countries are trying to increase the supply of renewable energy as the substitute of the fossil energy for reducing greenhouse gas emissions. However, renewable energy sources account for only about 3.86% of the total Korea primary energy supply. To increase the rate of renewable energy in Korea's energy consumption, various policies for expanding the use of renewable energy should be applied. Also these policies should be consider renewable energy resources distribution and regional inequality. In this study, the potentials of photovoltaic, wind power and bioenergy from rice straw, livestock waste and food waste are calculated and the distribution characteristic and regional inequalities are analyzed using Gini's coefficient and Gini decomposition method. As the results, technical potentials of photovoltaic and wind power of city region(Gu) has more potential rate than theoretical potentials. Livestock waste has the most unequal distribution (Gini's coefficient: 0.617) among renewable resources.

  • Vietnam is endowed with multiform new and renewable energy resources. However, potential of new and renewable resources in Vietnam has not been completely assessed. Although the Government has embarked several programs to expand the use of these resources, the share of new and renewable energy in total commercial energy is still insignificant. The purpose of this study is to summarize potential and current development status as well as the prospect of new and renewable energy. Identification of barriers that are the hindrances in the development of new and renewable energy would suggest measures to future commercialization of new and renewable energy.

  • This study explored the potential and implementation of renewable energy sources in Sri Lanka, focusing on the theoretical potential of solar and wind energy to develop self-reliant energy models. Using advanced climate data from the European Centre for Medium-Range Weather Forecasts and Global Solar/Wind Atlas provided by the World Bank, we assessed the renewable energy potential across Sri Lanka. This study proposes off-grid and minigrid systems as viable solutions for addressing energy poverty in rural regions. Rural villages were classified based on solar and wind resources, via which we proposed four distinct energy self-reliance models: Renewable-Dominant, Solar-Dominant, Wind-Dominant, and Diesel-Dominant. This study evaluates the economic viability of these models considering Sri Lanka's current energy market and technological environment. The outcomes highlight the necessity for employing diversified energy strategies to enhance the efficiency of the national power supply system and maximize the utilization of renewable resources, contributing to Sri Lanka's sustainable development and energy security.

  • Ministry of Commerce, Industry [MOCIE] has taken it into consideration to introduce a Renewable Portfolio Standard (RPS) that is a purchase obligation program as an alternative plan to the FIT. We conducted a survey of renewable energy companies and experts to ask their opinions about renewable energy policy, the introduction of the RPS, and the scheme for aid of North Korea with renewable energy. Korean renewable energy companies show an impartial opinion about a FIT and a RPS system overall, although they tend to have distinctive opinions by technology each other. With respect to eligible resources for a RPS, the industries want to extend the scope of it as broad as possible. In addition, experts prefer the multi-tiered and energy production based RPS to the sing1e-tiered and installed capacity based RPS. We also conducted a surrey to find the best renewable energy sources. Wind, Geothermal, Solar-thermal, and Photovoltaic were selected to have the best potential capacities to support North Korea by renewable energy experts. However, these energy resources also have several problems to overcome in the aid of North Korea, and thus, the plans for solving them and for giving efficient support to North Korea in the area of Renewable Energy are discussed.

  • A power system configuration has been increasingly advanced with a number of generating units. In particular, renewable energy resources are widely introduced due to the environmental issues. When applying the renewable energy sources with the ESS (Energy Storage System), the ESS is the role of a potential generating resource in the power system while mitigating the output volatility of renewable energy resources. Thus, for applications of the ESS, the surrounding environment of it should be considered, which means that capacity and energy of the ESS can be affected. Moreover, operation strategy of the ESS should be proposed according to the installation purpose as well as the surrounding environment. In the paper, operation strategy of the ESS is proposed considering load demand and the output of renewable energy resources on a hourly basis. Then, the cost of electrical energy is minimized based on the economic model that consists of capital cost, operation cost, fuel cost, and grid cost for a year. It is sure that peak-shaving effects can be achieved while satisfying the minimum cost of electrical energy.

  • Cameroon is a lower middle-income country with a population of 25.87 million inhabitants distributed over a surface area of 475,442 ㎢. Cameroon has very rich potentials in renewable energy resources such as solar energy, wind energy, small hydropower, geothermal energy and biomass. However, renewable energy constitutes less than 0.1% of energy mix of the country. The energy generation mix of Cameroon is dominated by large hydropower and thermal power. Cameroon ratified the Paris Agreement in July 2016 with an ambitious 20% greenhouse gas (GHG) emission reduction. This study attempts to investigate some renewable energy deployment policy-instruments that could enable the country enhance renewable energy deployment, gain energy independence, fulfill Nationally Determined Contribution (NDC) and achieve Sustainable Development Goals. It begins with an analysis of the status of energy sector in Cameroon. It further highlights the importance of renewable energy in mitigating climate change by decarbonizing the energy mix of the country to fulfill NDC and SDGs. Moreover, this study proposes some renewable energy deployment policy-solutions to the government. Solar energy is the most feasible renewable energy source in Cameroon. Feed-in Tariffs (FiT), is the best renewable energy support policy for Cameroon. Finally, this study concludes with some recommendations such as the necessity of building an Energy Storage System as well a renewable energy information and statistics infrastructure.

  • 최근 환경 오염 및 자원 고갈 등의 이유로 대체에너지원은 미래의 에너지원으로 중요한 역할을 하고 있다. 국외에서는 대체에너지원에 관련된 정보 시스템의 개발 및 보급이 활발히 추진되고 있다. 그러나 국내에서는 대체에너지원 데이터의 효율적인 이력 관리 및 웹을 통한 검색 서비스가 제공되지 않고 있다. 따라서 이 논문에서는 대체에너지원 데이터의 방대한 이력 정보를 체계적으로 저장 및 관리하기 위한 대체에너지원 이력 데이터 관리 시스템을 제안한다. 이 시스템은 외부 관측 시스템으로부터 대체에너지원 데이터를 수집하여 이력 데이터베이스에 저장한다. 저장된 정보는 이력 질의 처리를 통해 검색되고 테이블, 그래프, 챠트, 등고선 등의 다양한 형태로 인터넷을 통해 제공된다. 특히, 제안 시스템은 실시간으로 이력 데이터를 관리하므로 사용자는 웹 인터페이스를 통해 항상 최신의 정보를 제공받을 수 있는 특징을 갖는다.

  • 대체에너지원 데이터는 측정값이 시시각각으로 변경되는 특성을 갖기 때문에 시간의 변화에 따라 발생되는 원시 데이터의 양이 상당히 방대하다. 따라서 대체에너지원 데이터의 이력 정보를 체계적으로 저장 및 관리할 수 있는 이력 데이터베이스의 구축과 대체에너지원 예측 시스템에 대한 연구가 필요하다. 이 논문에서는 대체에너지원 데이터의 과거 측정값에 대한 추정 기능의 지원을 통해 시시각각으로 변화하는 데이터를 체계적으로 관리하기 위한 대체에너지원 추정 기법을 제안하였다.
