Abstract |
The combined heat and power system (CHP) is one of the representative distributed energy resources which provide various benefits to the power system. This paper estimates the transmission congestion relief benefits from the CHPs located in the metropolitan area in Korea Electricity Market. Based on the results of the electricity market operation, we extract the transmission congestion relief contribution to the power system from CHPs' excess generation due to the self-constraint. The calculated transmission congestion relief benefits are energy cost savings from the power system perspective and energy settlement cost savings from the utility perspective. The improved market settlement rules for the excess output due to the self-constraint are suggested, considering the transmission congestion relief contribution. |
