플랜트 산업은 기자재, 노동력, 기술이 함께 투입되는 종합산업으로 부가가치가 매우 높고, 선진국들의 수출전략산업으로 해외시장에서 치열한 수주경쟁이 벌어지고 있다. 우리나라도 플랜트 시장의 수출 증대는 매우 중요한 과제로 여겨지고 있다. 그러나 현재까지의 추세로 보아 우리나라의 플랜트 산업은 석유가스와 석유화학부문에 너무 치우쳐 있고 업체들간의 수주 불균형으로 인한 인력부족, 그리고 여러 기술적${\cdot}$비용적인 문제가 발생하고 있다. 이를 해결하기 위해서는 정확한 시장환경 분석을 통한 경영전략의 수립이 요구된다. 국내 건설업체들이 향후 지속적인 수익을 확보하기 위해서는 최근의 시장동향을 고려할 때 시장발전이 제한적인 국내시장 대신 해외시장에 진출하기 위한 전략의 확보가 요구된다. 조사 결과 해외 플랜트 시장의 발전 가능성에 비해 국내 업체들이 플랜트 시장에 진출하기에 시공분야에서는 오랜 경험을 바탕으로 충분한 경험을 갖고 있으나 고부가가치 분야인 엔지니어링, 사업관리 분야 등에 대해서는 매우 취약한 것으로 조사되었으며, 이로 인해 해외 업체들과의 수주 경쟁에서 뒤처지는 것으로 나타났다. 이에 본 연구는 국내 건설업체들이 플랜트 건설 분야에 경쟁력 강화를 위한 현 문제점을 지적하고 그에 대한 개선점을 제안하였다.

This paper addresses the bidding strategies of a pumped-storage hydro plant in an electricity market. Competitive bidding of pumping and generating of a pumped-storage plant is formulated in a game theoretic problem in accordance with the three different ownership of scheduling; Market Operator(MO), generating company(Genco), and combined type of MO and Genco. Optimal conditions for Nash Equilibrium are derived in the form of market prices during the scheduling periods. Simulation results show the different ownership models produce different schedules of pumping and generating, which correspond to the objective of the scheduling owner of a pumped-storage hydro plant.

Korea is worldwide top manufacturer of offshore plant industry, while shown weakness in high-valued offshore plant service industry (OPSI). The governmental support policies and studies for fostering programs are centered on shipbuilding and engineering sector. On the other hand, offshore logistics service sector among the programs is neither included as governmental fostering support sectors nor ever-studied. Domestic shipping and logistics companies have many experience of handling various project, heavy-lift cargo and even super blocks on shipbuilding industry. However they are faced with lack of appropriate heavy carrier and others. So for their successful entering into offshore plant logistics market, systematic preparation, studies and supporting policies are highly recommended.

When the energy resource available to a particular plant (be it coal, oil, gas, water, or nuclear fuel) is a limiting factor in the operation of the plant, the entire economic dispatch calculation must be done differently. Each economic dispatch calculation must account for what happened before and what will happen in the future. This paper presents a formulation and a solution method for the optimization problem with a fuel constraint in a competitive electricity market. Take-or- Pay (TOP) contract for an energy resource is the typical constraint as a limiting factor. Two approaches are proposed in this paper for modeling the dispatch calculation in a market mechanism. The approaches differ in the subject who considers and inserts the fuel-constraint into its optimization problem. Market operator and each power producer having a TOP contract are assumed as such subjects. The two approaches are compared from the viewpoint of profits. surplus. and social welfare on the basis of Nash Equilibrium.

The introduction of electricity industry provides generators incentives to recover the related cost through the market. Hence, the generator should sell his/her electricity at high market-clearing price with optimal operation of his/her power plant. The maintenance of power plant is the most critical factor in affecting generators' decision-making. This paper analyzes technique for establishing maintenance schedule reflecting recovery cost and considers differences in monthly load pattern in minimizing LOLP.

Seawater desalination has vest interest in terms of ultimate water resources for the countries suffering lack of water supply. Water demand is steadily increasing due to the population growth and industrialization in Asia. The objectives of this study are to prospect the desalination market in Asia countries including China, India and Singapore, and to propose possible strategies of getting through Asia water market. Water supply in China is increasing up to $5,322,060m^3$/d in 2015. Northeast coastal areas such as Tianjin, Shandong, Hubei, and Liaoning are expected rapid increase for water demand. The investment of water supply in India would be 1.74 billion dollars during 2006 to 2015. Chennai, Kutch, and Pondicherry have possibility in introducing seawater desalination plants. Singapore is focusing on water reuse, and operating three NEWater plants (water reuse plants). BOT with total solution providing financing, construction, operation etc. is an adequate strategy to getting through China water market, while desalination plant project connecting with power plant is desirable in India. The cooperative system with Korea and Singapore creates synergy effect regarding planning and operating experience of Singapore and EPC ability of Korea.

The use of renewable energy sources and energy storage systems is increasing due to new policies in the energy industries. However, the increase in distributed generation hinders the reliability of power systems. In order to stabilize power systems, a virtual power plant has been proposed as a novel power grid management system. The virtual power plant plays includes different distributed energy resources and energy storage systems. We define a core virtual power plant technology related to demand response and ancillary service for the cases of Korea, America, and Europe. We also suggest applications of the proposed virtual power plant to the vehicle-to-grid market for restructuring national power industries in Korea.

One of domestic power generation companies, Korea East-West Power Corporation(EWP) had no performance in overseas business just two short years ago. However, EWP has accomplished breakthrough results with the profit of KRW 17.8 billion in 2010, only overseas business part. With overseas power plant growing fast, there is a possibility that EWP may face the limitation of sustainable growth with the current low income structure, which is mainly focused on commissioning and power plant management. Accordingly, this study was made on overseas biomass plant business participation plan through the establishment of joint venture. The characteristics of a joint venture establishment was searched, choosing business partner; the ideas of how to organize a joint venture was drawn, what the role of each partner in joint venture is, and what proper capital share is; and chose business field, considering changing global energy mix, renewable energy market scale, and growth prospects. Considering government policy for renewable energy vitalization and renewable energy market share, We chose the European union as a market to which our business entered.

Worldwide plant market keeps maintaining steady growth rate and along with this trend, domestic plant market and its contractors also maintain such growing tendency. However, in spite of its external growth, win-win growth of domestic material industry that occupies the biggest share in plant industry cost portion is extremely marginal in reality. Domestic plant material suppliers are required to increase awareness of domestic material brand by securing quality and reliability of international standard through improvement of design quality superior to that of overseas material suppliers. Improvement of design quality of plant material becomes an essential element, not an option, for survival of domestic plant industry and its suppliers. Under this background, in this study, priority and importance by each evaluation index was analyzed by materializing plant design stage through survey of experts and defining evaluation index by each design stage and based on this analysis result, evaluation index of stage-gate based decision-making process that may improve design quality of plant material was suggested. It is considered that by utilizing evaluation index of stage-gate based decision-making process being suggested in this study, effective and efficient decision-making of project decision-makers would be enabled and it would be contributory to improve design quality of plant material.
