Congestion management in hybrid power markets

This paper proposes a one-step methodology for congestion management of a hybrid power market that consists of a power pool and bilateral contracts between market participants. The proposed method is based on a modified Optimal Power Flow (OPF) model to minimize the total cost of generation and ancillary services. Transmission losses, reactive power support and congestion relief are provided centrally in one optimization step. The benders decomposition technique is applied to solve the proposed OPF problem. The congestions are relieved through an iterative process, which makes the congestion management scheme transparent to all the market parties. The IEEE-RTS is analyzed to illustrate the proposed technique.
