A transmission network model for multi-area reliability studies

A transmission network suitable for use in multiarea power system reliability models which utilize a Monte Carlo simulation approach is presented. The transmission network model utilizes the REI equivalent, which permits accurate modeling of transmission ties between areas while reducing computational burden and permitting variations in area generating capacity and loads as required in reliability studies. A computationally efficient approach to generation redispatch as required to model mutual assistance between areas in multiarea reliability studies is presented. Sample results are given for the IEEE Std 118-bus test system and a large power pool with 13 areas
