【 摘 要 】

Korea Electric Power Market divided the Korea Electric Power Corporation;;s power generation subsidiaries into five by restructuring and established The Electricity Regulatory Commission(KOREC) and Korea Power Exchange(KPX)in April 2001. KEPCO remained as the operator of the grid and power system, while the subsidiaries of electricity generation were forced to produce electricity by thermoelectric, nuclear and hydro power plant. After these divisions and established as a stakeholder, rather than as a company, areas of business from each company were overlapping or blurred as they operated their systems.In the situation, Korea Power Exchange(KPX) shut down gradually on September 15, 2011, resulting in a regional power cycle blackout. Traffic lights have stopped working throughout the city, and vehicles and pedestrians are in chaos. The power outage caused quite a bit of damage throughout the nation. As the reliability of the power system was emphasized more, it became an important criterion for the design and analysis of electrical equipment (transmission line, power plant, etc.) [1]As a result of this and other major changes in the power industry, recently, a new technology called High Voltage Direct current(HVDC) has emerged worldwide. This technology has many advantages such as the ground-grounding of transmission lines and is currently being operated and constructed in Korea. It was already applied to Jeju - Haenam (completed in 1998) and Jeju - Jindo (completed in 2013).In response to this rapidly changing power industry, the nation has yet to apply the change to its institutions and regulations at once. In particular, in the construction of the HVDC facility, it is not clear whether the facility is a access facility for specific customers or a common grid to be used by many customers. Therefore, it is highly probable that the problem of cost sharing occurs between the TSO-GENCO, or GENCO-GENCO, that has become the respective stakeholders.Therefore, in this paper, the two plans for sharing the costs of the HVDC construction, including those of the power industry, improving reliability of the power system, and developing the power industry. First, domestic and external cases and situations are investigated concerning the method of sharing costs between TSO and GENCO to explore measures suitable for Korea. Second, the power flow sensitivity analysis [LODF : Line Outage Distribution Factor] and the simulation method are proposed for sharing the cost for the simulated system(PSS/E) as a result of adding new power lines between the GENCO and GENCO.
