REINFORCEMENT OF POWER SYSTEM RELIABILITY MEASURES THROUGH JOINT DETERMINISTIC AND PROBABILISTIC APPROACHES

Abstract

By adapting the emerging conceptualization of reliability network equivalents, originally developed to obtain reliability indices in the restructured scenario, a suitable framework encapsulating relatively independent modularity could be evolved that shall enable the application of joint deterministic- probabilistic well being-analysis for the composite restructured power systems. Reliability management forms the core component of successful transition from vertical integration of power systems to their deregulation. Timely reinforcements to the resource adequacy will ensure reliably operating power systems. Redundancy apportioning without pessimistic appraisals or exceedingly optimistic estimates is a vital ingredient for the success of restructured systems. With these goals in mind, this paper puts forward a philosophical modeling paradigm that investigates the feasibility of extending the hybrid approach of well-being analysis to a composite bilateral contracts market structure, a potential indicator of generation reinforcements to gear up for. Probabilistic load flow studies as a means to justify transmission reinforcements is also brought forward. Also presented is an overview of the reliability cost-worth methods, information from which forms an integral part of the reinforcement strategies.
