ASSESSMENT OF RESERV E ADEQUACY AND RELIA BILITY OF POWER SYST EMS

This paper presents an innovative approach to reserve adequacy and reliability assessment in bulk electricity systems based on the widely accepted international standards and guidelines. In the presented approach, the electricity reserve associated with a particular operating bulk area is modeled as a random function of three key random operating variables, namely the area generation capacity, the consumer demand, and the area in/out tie - line transfer capa city. The approach followed in this paper allows the evaluation and assessment of the sensitivities of the area reserve and other reliability performance measures with respect to variations in the system planning and operating conditions. The developed app roach has been successfully applied to several operating scenarios in a real - life power system consisting of the Hail area in the Saudi Electricity Company.
