A TRANSMISSION NETWORK MODEL FOR MULTIAREA RELIABILITY STUDIES

The paper presents a transmission network model suitable for use in mu lti-area reliability models which utilize a Monte Carlo simulation app roach. The transmission network model utilizes the REI equivalent whic h permits accurate modeling of transmission ties between areas while r educing computational burden and permitting variations in area generat ing capacity and loads as required in reliability studies. The paper a lso presents a computationally efficient approach to generation redisp atch as required to model mutual assistance between areas in multi-are a reliability studies. Sample results are given for the IEEE 118 bus t est system and a large power pool with 13 areas.
