This paper proposes establishment of generator maintenance scheduling(GMS) considering minimization of CO₂ emissions. The objective function model to minimize CO₂ emissions is used in this paper. In this paper, and also, GMS is established due to freedom of GMS of generators owned by a designated generation company. The practicality and effectiveness of the proposed approach are demonstrated by simulation studies for a real size power system model in Korea in 2010.

The maintenance of generating units is implicitly related with power system reliability and has a tremendous bearing on the operation of the power system. A technique using a fuzzy search method which is based on fuzzy multi-criteria function has been proposed for GMS (generator maintenance scheduling) in order to consider multi-objective function. In this study, a new technique using combined fuzzy set theory and genetic algorithm(GA) is proposed for generator maintenance scheduling. The genetic algorithm(GA) is expected to make up for that fuzzy search method might search the local solution. The effectiveness of the proposed approach is demonstrated by the simulation results on a practical size test systems.

The CO₂ emission can be decreased due to freedom of generator maintenance scheduling(GMS). This paper proposes assessment of CO₂ emissions in generator maintenance scheduling considering hydro and pumped generator. And also, this paper assesses the CO₂ emission due to freedom of GMS of generators owned by a designated generation company. The minimum reliability criterion level satisfied production cost minimization function model is used in this paper. The practicality and effectiveness of the proposed approach are demonstrated by simulation studies for a real size power system model in Korea in 2010.

This paper proposes a short-term load forecasting algorithm using the sensitivity of temperature in a summer season. The sensitivity of temperature is used to improve the accuracy of the load forecasting through the relation of daily load and daily high temperature. Case studies were applied to load forecasting for summer of 2009, and the results shows its appropriate accuracy.

Load forecating is very important for power system analysis and planning. This paper suggests a annual load forecasting by using trend method with considering peak load. Each yearly peak load is normalized and the average value is calculated. The new hourly peak load is forecasted by using average value and annual peak load. As a result, the actual data and forecast data were compared and the effectiveness of the proposed method is verified.

The CO₂ emission can be decreased due to freedom of generator maintenance scheduling(GMS). This paper proposes assessment of CO₂ emission considering generator maintenance scheduling(GMS) and evaluates effect of the GMS on CO₂ emission. And also, this paper assesses the CO2 emission and the probabilistic production cost simulation of nuclear and thermal power generators considering operation of hydro and pumped generator. The minimum reliability criterion level satisfied production cost minimization function model is used in this paper. The practicality and effectiveness of the proposed approach are demonstrated by simulation studies for a real size power system in Korea in 2010.
