Abstract
Power system deregulation has increased the need for determination of transmission reliability margin (TRM) which is the amount of transfer capability reserved to ensure that the transmission network is secure under a reasonable range of uncertainty in system operating conditions. This paper presents a computationally effective method in determining the TRM based on the first order sensitivity of transfer capability and certain probabilities. The first order sensitivity determines linearly the changes of transfer margin uncertainty with respect to the standard deviation uncertainty of transmission line reactances. The TRM is determined by considering the effect of maximum forecasted peak load during the outages of critical lines and generators. Verification of the TRM method is illustrated in conjunction with the determination of the available transfer capability and tested on a practical power system as a pragmatic case study.
