Analysis on reserve effects on congestion management results in an integrated energy and reserve power market

The unstoppable increase in the capacity of power generation and also the stability problems due to the capacity of transmission lines cause new and different congestion management methods to be appeared in power systems. This paper proposes a congestion management method based on Optimal Power Flow (OPF) in order to analyze the effect of reserve generation in total generation and total cost of a power system. The optimization method which is used in OPF is Differential Evolution algorithm. The proposed method is applied on IEEE 24-bus RTS system and the result including power generation and the cost of the energy and reserve power production are presented and compared before and after congestion management and also with and without the existence of reserve generation.
