Almost, concerns for research of the customer interrupt cost are evaluation and analysis and customer interruption cost of commerce isn't active in evaluation. Therefore, In this paper, we calculate customer interruption cost of commerce and in case of occurring interruption of electrical power we evaluate how much damages occur.

This paper assesses interruption costs on the industry load through using the microscopic method. For assessment, the questionnaire was made on Korea Standard Industry Categorization which is composed of 28 type of industry Then, the survey was distributed to 1889 business in 12 area by staffs of KEPCO. The collected data is changed to the trustworthy data by using Bad Data Selection method and then the interruption costs of industry load was calculated by Tobit Regression which is tool analysing both collected data and the others.

In this paper, the method on calculating benefits of combined heat and power is introduced for standard evaluation in electrical power system. This paper calculates benefits about new national viewpoint and viewpoint of independent power producers and assesses benefits of combined heat and power in Korea and In Seoul national capital area. Benefit costs are composed of avoid cost of centralized generation, line upgrading adjustment, loss adjustment and electrical power trade cost per year in earlier study, in addition trade cost of CO₂, construction cost of combined heat and power for accurate calculation. Benefit of combined heat and power is calculated by simulation results of real electrical power system.

This purpose of this paper is to propose a methodology for optimal generating operation in power system to minimize the cost of generation subject to not only system constraints but also regional CO₂ emission constraints. To solve this ELD problem calculated range limit on minimum and maximum power outputs by regional Equal Generator how each regional capacity is connected into one and expressed Equal Fuel Cost Function considering regional CO₂ emission constraints. Accordingly, being modified regional load, new power outputs considering regional CO₂ emission constraints were calculated by ELD. The proposed model for evaluating availability is tested on IEEE RTS(Reliability Test System)-24 in detail.

Recently, Industry want to be supplied of high quality and reliability electrical power. In case that occurred In industry which want to be supplied of high quality and reliability electrical power, we evaluate sector customer damage cost in industry and then We consider and evaluate effect on supply reliability objectively.
