Abstract

In the environment of the power market, available transfer capability is a measure of transfer capability as the technical and commercial indices. In order to meet the requirement of generation reliability by obtaining the support from interconnected areas, the reserve transfer capability of the transmission lines is defined as capacity benefit margin (CBM). At present, CBM is evaluated and optimised through reliability calculation iteration. According to the influence of reserve capacity (or interface transmission capability, reserve clearing prices), three optimisation models are established based on the multi-area generation reliability exponential analytic model, then the sequential quadratic programming is used to solve the CBM of transmission tie lines with respect to variable reliability levels. Because of the analytic model, reliability is calculated only one time, needs no iteration and the coupling influence between areas is taken into account, the optimal results can be computed faster. Test results on TH-RTS show that this method is precise and effective.
