A Study of Average Transmission Congestion Distribution Factors for ATC

Available transfer capacity (ATC) is a key factor in power transactions and commercial activity in deregulated power networks. ATC for power systems refers to the transfer capacity left in the physical transmission network for more commercial activity beyond what has already been committed. Because of power system deregulation, a competitive electricity market is emerging that supports alternative energy sources such as wind, small hydro, solar, and so on. Wind energy is the fastest growing renewable energy source since it is clean and abundant in nature. The addition of wind power may increase the ATC value of the agreements. A repeated alternating current power flow (RACPF) technique to ATC computation has been developed. Rarely has study been conducted on the ATC model and its computation in the presence of WTs linked to the power grid. An efficient ATC calculation approach for WPG-containing power systems should be developed. Much study has been conducted on the ATC model and computation in order to alleviate congestion.
