A systematic approach to small-signal modelling of a micro-grid system that includes conventional (rotating machine) and electronically interfaced distributed resource (DR) units is presented here. The proposed approach incorporates fundamental frequency deviations in the overall system model and provides a methodology for the analysis of autonomous(More)

This paper proposes and develops a new distributed slack bus (DSB) model , in the sequence-components frame, for power-flow analysis of an islanded active distribution network (ADN) dominated by electronically coupled distributed energy resource (DER) units. The power-flow analysis distributes the system slack among several participating sources since,(More)

Brain drain or human capital flight is a large emigration of individuals with technical skills or knowledge, normally due to conflict, lack of opportunity, political instability, or health risks. A brain drain is usually regarded as an economic cost, since emigrants usually take with them the fraction of value of their training sponsored by the government.(More)
This paper presents an Interior Pont Method (IPM) and variant of Particle Swarm Optimization (CFAPSO) based hybrid method to solve optimal power flow in power system incorpo-rating Flexible AC Transmission Systems (FACTS) such as Thyristor Controlled Phase Shifter (TCPS) for minimization of multiple objectives. The proposed IPM-CFAPSO algorithm identifies(More)
