  • At present, the Korean electricity industry is undergoing restructuring and the Cost Based-generation Pool(CBP) market is being operated preparing for Two Way Bidding Pool(TWBP) market open. As the circumstance of the traditional system is changed according to power system deregulation, the simulation tool which should reflect market code providing market operating mechanism is needed to analyze an electricity market. This paper presents the development of an unique market simulator, Market Modeling and Price Simulator(MMPS) that is designed to imitate the Korean electricity market considering uniform price. The MMPS is developed in VB.NET and is composed of two modules that consist of market modeling and price simulation interfacing access database program. To evidence the features and the performance of MMPS, a small two way bidding market with 12-bus system and one way bidding market for generator competition will be presented for the electricity market simulations using MMPS.

  • At present, the Korean electricity industry is undergoing restructuring and the Cost Based-generation Pool (CBP) market is being operated in preparation of a Two Way Bidding Pool (TWBP) market. In deregulated electricity industries, an integrated power market simulator is one of the tools that can be used by market participants and market operators analyzing market behaviors and studying market structures and market codes. In this regard, it is very important to develop an electricity market simulator that reflects market code providing a market operation mechanism. This paper presents the development of an integrated market simulator, called the Power Exchange Simulator (PEXSIM), which is designed to imitate the Korean electricity market considering the various features of the market operating mechanism such as uniform price and constrained on/off payment. The PEXSIM is developed in VB.NET and composed of five modules whose titles are M-SIM, P-SIM, O-SIM, T-SIM and G-SIM interfacing the Access database program. To verify the features and the performance of the PEXSIM, a small Two Way bidding market with a 12-bus system and a One Way bidding market for generator competition will be presented for the electricity market simulations using PEXSIM.

  • The vertically integrated power industry was divided into six generation companies and one market operator, where electricity trading was launched at power exchange. In this environment, the profits of each generation companies are guaranteed according to utilization of their own generation equipments. Especially, the electricity demand shows seasonal and weekly regular pattern, which the some capacity should be provided into ancillary service based on the past demand forecasting error and operating results of electricity market. Namely, if generation cost function is applied to SMP and BLMP as announced the previous day, the available generation capacity of the following day could be optimally distributed, and therefore contract capacity of ancillary service applied to CBP(Cost Based Pool) and TWBP(Two-Way Bidding Pool) is determined. Consequently, it is Possible to use the retained equipments optimally. This paper represents on efficient bidding strategies for generation equipments through the calculation of the contract and the application of each generator cost function based on the past demand forecasting error and market operating data.

  • 본 논문에서는 쿠르노 모형을 적용한 양방향입찰 전력 풀시장에서 입찰에 참여하는 발전기가 최대 이익을 얻기 위한 입찰전략으로서 신경회로망의 오차 역전파 알고리즘을 이용하여 최적 입찰발전량과 입찰가격을 수립하는 기법에 관하여 연구한다. 전력시장 환경은 n 개의 발전기들이 참여하는 비협조적 불완전정보 시장으로 설정하고 Bayesian의 조건부 확률이론을 적용하여 상대 발전기들의 발전비용함수와 시장의 수요함수를 추정하여 발전기 상호간 쿠르노-내쉬균형점을 이루는 최적 입찰발전량을 예측한다. 그리고 이익을 극대화시키기 위해 오차 역전파 알고리즘을 이용하여 시장의 가격 탄력성과 쿠르노 시장균형가격에 연결가중치를 조절함으로써 입찰가격이 계통한계가격에 근접하도록 최적 입찰전략을 수립한다.

  • In competitive electricity markets, the System Operator (SO) coordinates the overall maintenance schedules whenever the collective maintenance schedule reported to SO by Gencos in the pool does not satisfy the specified operating criteria, such as system reliability or supply adequacy. The SO's coordination usually involves sorts of financial conflict among Genco's. This paper proposes a coordination algorithm which minimizes the total financial loss of Genco's while satisfying the required operating criteria.

  • This paper proposes the level of price cap in the TWBP(Two- Way Bidding Pool) market in Korea for which the draft of market design has been prepared by KPX. Max - GMCP(Maximum Generation Market Clearing Price) and APC(Administered Price Cap) would be separately applied as individual price caps for a normal period and a Price Capping period in TWBP. The level of price cap is determined for inducing optimal investment in the Korean Electricity Market considering the 'electricity resource baseline plan' published by the Korean government in 2002 for maintaining government-leading resource planning in Korea. In this regard, Max - GMCP is calculated from the equilibrium condition of investment based on reliability standard and fixed cost of the peaking plant. For verifying the propriety of the proposed price cap, this paper compares the proposed value with the estimated VoLL(Value of Lost Load) based on Korea's GDP(Gross Domestic Product).

  • 2001년 전력산업의 구조개편에 따라 우리나라는 현재 발전경쟁시장(CBP)을 운영하고 있으며, 이어서 도매경쟁시장(TWBP)의 개설을 준비하고 있다. 도매경쟁시장에서의 계통운영 보조서비스는 전력거래소와 발전사업자간의 계약에 의하여 제공되며, 전력거래소는 전력계통 신뢰도 및 전기품질 유지기준을 만족시킬 수 있도록 보조서비스 필요량을 정하여 운영하게 된다. 본 논문은 도매경쟁시장에서 적용할 주파수제어보조서비스 중 정상상태의 주파수 제어에 사용되는 자동발전제어(AGC)에 대하여 실계통 운영 실적자료 분석을 통한 AGC 필요량 산정방안을 제안하고, 적정필요량을 검토하였다.

  • 전력산업에 당초 도입 예정되었던 도매경쟁시장을 운영지원하기 위하여 전력거래소는 지난 2002년 도매경쟁 전력시장 운영시스템(Two Way Bidding Pool Market Operation System; TWBP MOS, 이하 전력시장운영시스템)을 구축하였다. 그러나 이후 배전분할 잠정 중단정책에 따라 구축 완료된 시스템은 실 업무에 적용해보지도 못한 채 폐기될 수도 있는 상황이 발생하였다. 하지만 전력거래소는 배전분할 잠정 중단에 따른 발전 경쟁시장(CBP; Cost-Based Pool) 장기화에 대비, 운영상의 효율성을 개선하고 기 개발된 전력시장운영시스템을 활용하여 급전체계를 개선하는데 성공하였다. 실시간 급전 운영을 위해 기존 EMS에 전력시장운영시스템을 연계하여 전력시장운영시스템의 5분 단위 수요 예측량을 기반으로 송전망 제약과 예비력 요구량 등을 고려한 발전기별 경제부하 배분량 및 예비력 배분량을 결정하고, 추가적으로 EMS에서 수요예측 오차 및 주파수 보정량을 실시간으로 계산하여 발전기별로 배분하도록 함으로써, 1일 전 시행하던 급전계획을 취득 자료를 기반으로 5분 단위로 실시간 계산할 수 있도록 급전 개선하였다. 이를 통해 실시간으로 에너지와 예비력을 동시에 최적화함으로써 전력시장 및 전력계통 운영을 한층 선진화 할 수 있는 계기를 마련하였으며 또한 저비용 발전기 사용을 극대화함으로 발전비용의 절감에도 기여하는 효과를 가져왔다. 이러한 긍정적인 효과에도 불구하고, 전력시장윤영 시스템은 구축된 모든 설비 및 프로그램을 당초 목적에 맞게 활용하지 못한다는 이유 등으로 시스템의 최적화 및 성능 개선에 대한 투자가 망설여지는 현실이다. 특히 온라인 실시간 시스템과 별도로 전력시장운영을 모의 할 수 있는 시뮬레이터가 구축되지 않아 시장의 흐름을 사전 예측하거나 시스템 오류 등을 재현하여 재발 대책 등을 마련하기가 매우 어려운 실정이다. 이에 본 논문에서는 그동안 쌓아온 전력거래소의 전력시장운영시스템 운영관리에 대한 다양한 경험을 바탕으로 구축비용을 획기적으로 절감할 수 있는 전력시장운영시스템 시뮬레이터의 구축방안을 제시하고자 한다.
