Nodal probabilistic congestion and reliability evaluations of a transmission system under the deregulated electricity market
This paper presents a method for evaluating nodal probabilistic congestion and reliability indices of transmission systems. Quantitative evaluation of transmission system reliability is very important because successful operation of an electric power system in the deregulated electricity market depends on transmission system reliability management. The key point is that the reliability level of the transmission system is equal to the reliability level difference between the composite power system (HLH) and the generation system (HLI). Risk indices of a composite power systems are larger than those of the generation system as the composite power systems include uncertainties and capacity limits of the transmission lines. The characteristics and effectiveness of this methodology are illustrated by the case study using a small test system.
