Continuous integration congestion cost allocation based on sensitivity

Suppressing of gaming in power trading under deregulated environment

“…Power flow calculation is carried out in each iteration, but problem become apparent in this method when there is much iteration times [8][9][10]. Wu et al [11] proposed continuous integration congestion cost allocation method based on sensitivity. This method in comparison with method based on using the quadratic method and inner point iteration needs a less computation time.…”

“…The energy charge is calculated by putting equations (11) & (14) in equation (15) total payment by including actual congestion charges, Energy charge = line charges minus actual profit by transaction III RESULT AND DISCUSSION The system considered includes three cases: CASE -I, the first case shown in figure 2(a) and 2(b). The two area system is shown by 2(a).…”

An Advanced Method of Congestion Management for Optimal Energy Pricing

“…Congestion levels typically determine the security of a power system, which would have further consequences on market transaction and energy prices. Market operators have been using the DC-OPF for dispatching power and clearing energy (Farmer et al, 1995;Hogan, 1998;Singh et al, 1998;Karaki et al, 2002;Niimura & Niu, 2002;Fonseka & Shrestha, 2004;Hamoud & Bradley, 2004;Dan et al, 2006) to determine the LMP due to its speed and robustness, particularly in market simulation and planning (Wu et al, 2004;Junjie & Tesfatsion, 2007;Li & Bo, 2007). Generally, the DC-OPF is used for security constrained economic dispatch and redispatch when controlling transmission congestion while maximising the economic power transfer capability of the transmission system without violating its constraints (Kafka, 1999;Yajing et al, 2006;Gomes & Saraiva, 2007;Rodrigues & Silva, 2007).…”
