OPERATING RESERVE ASSESSMENT IN MULTI-INTERCONNECTED SYSTEMS

Abstract

This thesis examines the determination of operating reserves in single and interconnected systems. Security constraints have been included and techniques for risk evaluation in multi interconnected system allocation of system spinning reserves and unit commitment have been developed. Load forecast uncertainty, partial generating unit outage states, rapid start gas turbine and hot reserve generation and the assistance from- interconnections have also been included in the analysis. The incorporation of these factors in the analysis permits a quantitative approach to operating a system at a pre-determined level of reliability. Reliability and economics cannot be considered as two separate entities. Pertinent economic system operation techniques have also been ut:lized in this thesis to schedule the system generation at an assigned risk level. A digital computer program has been developed for incorporation of all these factors in a practical system study. Models of the Saskatchewan Power Corporation (S.P.C.) and the Manitoba Hydro (M.H.) systems have been utilized for a wide range of studies. The techniques developed in this thesis can be used to coordinate the incremental operating costs and the incremental reliability costs in a practical system to obtain minimum cost operation at an acceptable risk level.
