This paper presents a lifetime efficiency index model and a developed crow search algorithm (DCSA) in order to achieve optimal maintenance for the power transformer. Not doing maintenance on the power transformer, resulting in instability of the transmission system and not to supply consistently electric energy in the load points. In other words, deterioration of the transmission system effects...

In this paper, the performance of two types of FACTS devices in order to enhance the power system static voltage stability has been investigated. These devices include Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC). The modeling of the Single Machine Infinite Bus (SMIB) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...

This paper addresses the bidding problem faced by a virtual power plant (VPP) in energy, spinning reserve service, and reactive power service market simultaneously. Therefore, a non-equilibrium model based on security constraints price-based unit commitment (SCPBUC), which is take into account the supply-demand balancing and security constraints of VPP, is proposed. By the presented model, VPP ...

Abstract: Distribution economic burden in power system is one of the important and essential issues in power plant production planning. This thesis presents the economic burden for generating power plants with smooth and uneven functions and considering the constraints of the power plant (steam valve, forbidden areas, with and without transmission losses) in a multi-generator power system. The ...

Congestion Risk Management is one of the most important subjects of Transmission management in deregulated power system and world electricity market, especially markets of zonal or local pricing in which Firm Transmission Rights (in other words Financial Transmission Rights) are the main elements. In this study, considering subjects of Financial Rights of Transmission Congestion, methods of opt...
