Determining Operating Reserve Requirement in a Competitive Market Using Dynamic Approach

Abstract

Operating reserve is essential for system operator to maintain reliable operation of power system in real time. Traditionally, static approaches are used to establish the required capacity for operating reserves. A novel method is suggested in this paper by considering interrelation between secondary, tertiary reserve and load shedding to determine operating reserve requirement. The first part of this paper explains the basic concept of frequency control. Then new method to determine operating reserve requirement is supposed with consideration of interrelationship among different reserves under a simultaneous co-optimization scheme of various ancillary services. 
