Abstract

This paper presents an operating reserve risk assessment procedure for composite generation and transmission systems. This method is utilized to study risk constrained unit commitment under various system operating conditions. The unit commitment studies are done on composite generation and transmission system and recognize common mode failures of transmission lines and station initiated outages. The procedure presented in this paper incorporates a physical appreciation of the effect of transmission lines and station elements on the composite system operating risk index and therefore on the units committed for operation. This procedure is illustrated by application to the hypothetical test system designated as the RBTS
