Purpose The purpose of this study is to design a regional electricity planning model rather than the existing single region ones and verify its usefulness. The regional electricity planning model is to determine both electricity distribution among regions and power plant planning at the same time satisfying regional demands and distribution networks. Design/methodology/approach This study made a regional electricity planning model by integrating power plant planning and electricity distribution among regions. The regional electricity planning model is formulated into a linear programming problem, and coded and run using the OSeMOSYS, one of open source energy systems. Findings According to the empirical analysis result, this study confirmed that the regional electricity planning model proposed in this study deducts the unfairness among regions in view of electricity and green house gas. In addition, the model is expected to be used in evaluating and developing the national policies concerning fine dust and/or green house gas.

The increasing cost, and demand for, household energy has increased attention to the phenomena of energy burdens. Despite this increased attention, a lack of consensus remains in pinpointing the strongest predictors, and geographic differences, that exist within the energy ecosystem. This study addresses this gap by utilizing a series of dummy variable regressions across cities, suburbs, and rural areas within Erie County, New York-a county noted to have particularly high energy burdens. Specifically, three types of predictor sets were incorporated into the methodology: a set of socioeconomic variables, physical variables, and a combination of both variable sets. The results of this study suggest that cities tend to have the highest electricity burdens. Despite the aging infrastructure in Erie County, high energy burdens were driven primarily by socioeconomic factors such as housing cost burden and poverty status. Lastly, this study explores various planning and policy implications Erie County can utilize to reduce energy burdens. In turn, this study highlights the importance of focusing policy efforts on existing social service programs to provide support to the region's neediest households.

Deregulations and market practices in power industry have brought great challenges to the system planning area. In particular, they introduce a variety of uncertainties to system planning. New techniques are required to cope with such uncertainties. As a promising approach, probabilistic methods are attracting more and more attentions by system planners. In small signal stability analysis, generation control parameters play an important role in determining the stability margin. The objective of this paper is to investigate power system state matrix sensitivity characteristics with respect to system parameter uncertainties with analytical and numerical approaches and to identify those parameters have great impact on system eigenvalues, therefore, the system stability properties. Those identified parameter variations need to be investigated with priority. The results can be used to help Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) perform planning studies under the open access environment.

Since Paris Climate Change Conference in 2015, many policies to reduce the emission of greenhouse gas have been accelerating, which are mainly related to renewable energy resources and micro-grid. Presently, the technology development and demonstration projects are mostly focused on diversifying the power resources by adding wind turbine, photo-voltaic and battery storage system in the island-type small micro-grid. It is expected that the large-scaled micro-grid projects based on the regional district and town/complex city, e.g. the block type micro-grid project in Daegu national industrial complex will proceed in the near future. In this case, the economic cost or the carbon emission can be optimized by the efficient operation of energy mix and the appropriate construction of electric and heat supplying facilities such as cogeneration, renewable energy resources, BESS, thermal storage and the existing heat and electricity supplying networks. However, when planning a large residential town or city, the concrete plan of the energy infrastructure has not been established until the construction plan stage and provided by the individual energy suppliers of water, heat, electricity and gas. So, it is difficult to build the efficient energy portfolio considering the characteristics of town or city. This paper introduces an energy mix optimization(EMO) method to determine the optimal capacity of thermal and electric resources which can be applied in the design stage of the real large-scaled residential town or city, and examines the feasibility of the proposed method by applying the real heat and electricity demand data of large-scale residential towns with thousands of households and by comparing the result of HOMER simulation developed by National Renewable Energy Laboratory(NREL).

본 연구는 메콩 유역 내 최대의 전력/에너지 소비 국가인 태국의 전력/에너지 체제를 살펴보는 것을 목적으로 한다. 태국의 전력/에너지 인프라 정책은 국경 내에서 머무는 것이 아니라 메콩유역국가들간, 더 나아가 아세안의 전력교류 및 경제통합과도 긴밀한 연계를 맺고 있다. 따라서 본 연구는 태국의 국내적 차원(national level)뿐만 아니라 대륙부 메콩을 아우르는 지역적 차원(sub-regional level)에서 태국의 전력/에너지 체제가 어떻게 형성되었고 현재까지 변화되어 왔는지까지 검토하였다. 한편, 2015년 파리협정을 기점으로 출범하게 될 신(新)기후체제 하에서 선진국뿐만 아니라 개발도상국도 기후변화 대응에 대한 자발적 책임과 감축의 의무가 주어진 만큼 태국도 기존의 전력/에너지 정책의 수정이 불가피해졌다. 따라서 우리는 태국의 최근 에너지 정책을 검토함으로써 지속가능한 에너지 체제로의 전환 가능성을 평가해보았다. 또한 태국의 시민사회가 국가의 전력/에너지 계획 설정에 미친 영향을 살펴봄으로써 향후 태국의 에너지와 기후변화 분야에서 시민사회의 역할에 대한 논의를 전개하였다. 분석 결과 먼저 태국의 전력/에너지 체제는 냉전 시대 하에서 미국 등 서방세계의 지원으로 급속 성장하였음을 확인할 수 있었다. 특히 이 과정에서 태국전력공사(EGAT)는 태국 에너지 정책에 있어 핵심적인 행위자로 작용하였다. 또한, 태국의 지리적 위치와 주변 국가에 비해 상대적으로 높은 경제 수준은 향후 지역 내 전력망 구축에 있어서도 그 중요성이 계속 부각될 전망이다. 다른 한편, 2015년에 수립된 태국통합에너지청사진을 에너지 트릴레마의 분석틀로 검토한 결과 태국은 여전히 환경적 지속가능성 측면에서 취약점을 드러내고 있어 지역적 차원의 환경적 고려가 필요함을 확인할 수 있었다. 마지막으로 태국의 시민사회는 지금까지 다양한 방식으로 국가의 전력/에너지 정책 및 기후변화 정책에 영향을 미쳐왔으나, 2014년 쿠데타 이후 그 움직임이 많이 둔화된 상태이다. 결론적으로 본 연구는 태국뿐 아니라 메콩 지역의 지속가능한 전환을 위하여, 태국의 현 전력/에너지 체제와 정책 방향에 대한 지속적 관찰을 제안하며, 이를 위해 태국 및 메콩지역의 정부 뿐 아니라 시민사회 진영과 다양한 노력에 협조할 필요가 있음을 제안한다.

Many severe earthquakes have occurred along the main fault lines in the world. In recent years, there has been a high incidence of small- and large-scale earthquakes in our country. These occurrences of earthquakes have become increasingly serious, owing to a degrading earth environment. An earthquake, in general, causes far more serious damages like disruptions in electricity or gas facilities, and fire disasters from its annexed effects than by its vibrations or the shock itself. In this paper, we present a countermeasure and its necessity in safeguarding against fire disasters in regional heritage villages such as "Asan Oeam," "Jeonju Hanok," and "Andong Hahoe." A more systematic and effective strategy for prevention systems against severe fire disasters is proposed after performing various related investigations and analyses of existing domestic and international systems. We investigated the existing fire security systems and their historical records with the tendency of earthquake occurrences in these three folk villages. In this proposal, we present a strategic approach for safeguarding against fire damages in our regional heritage villages derived from ICT (information communication technology)-based DPD (disaster prevention design), after examining the laws and regulations of fire-prevention strategies in Japan, America, and Europe.
