This paper introduces, for the first time to our knowledge, physics-informed neural networks accurately estimate AC-OPF result and delivers rigorous guarantees about their performance. Power system operators, along with several other actors, are increasingly using Optimal Flow (OPF) algorithms a wide number of applications, including planning real-time operations. However, in its original form,...

This paper presents an optimal power flow method based on the generation rescheduling priority to enhance transient stability in power systems. In order to determine the generation rescheduling priority the energy margin sensitivity indices are calculated. The candidate generators for generation rescheduling are determined by the energy margin sensitivity indices and then optimal power flow (OP...

In a de-regulated open access environment, reactive power is one of the ancillary services which must be provided by an Independent System Operator (ISO). In this paper, a new algorithm is proposed in which reactive power resources are initially so tuned that optimum security in terms of voltage profile and voltage stability are achieved while at the same time, the system losses are minimized. ...

Reactive power as a utility of ancillary service in restructured environment is supplied by Independent System Operator (ISO). Due to the particular importance of optimal pricing strategy in the power market, the study aims to investigate this problem more closely. To this end, first the problems of restructuring, reactive power generation and its associated costs thereof were reviewed and diff...

1639 Venkateswara and Kumar Firefly Algorithm based Optimal Power Flow with Static VAR Compensator for Improvement of Power System Security under Network Contingency  Abstract— At present owing to the increase in power demand power system have become more complex and heavily loaded, and are subjected to unstable or insecure operations. In order to provide a secure operation of the power system...

Optimal Power Flow (OPF) is one of the main functions of Power Generation Operation and Control. It determines the optimal settings of generating units, bus voltage, and transformer tap and shunt elements in Power System with the objective of minimizing total production costs or losses while the system is operating within its security limits. The aim of this paper is to propose a methodology (G...

Incorporating STATCOM into existing power flow (PF) or optimal (OPF) algorithm usually requires the development of complex program codes to represent associated derivatives introduced by models. This procedure is time consuming as it may require various corrections errors before having a suitable that effectively solves problem. To avoid this stress, an efficient way incorporating STATCOM’s mod...
