Influence of the supply of reactive power in the calculation of the transfer capability
(2004-12-01)
This paper presents some initial concepts for including reactive power in linear methods for computing Available Transfer Capability (ATC). It is proposed an approximation for the reactive power flows computation that uses ...
Distributed generation modelling for unbalanced three-phase power flow calculations in smart grids
(2011-05-31)
Distributed Generators (DG) are generally modeled as PQ or PV buses in power flow studies. But in order to integrate DG units into the distribution systems and control the reactive power injection it is necessary to know ...

VAr planning using genetic algorithm and linear programming
(2001-05-01)
A combined methodology consisting of successive linear programming (SLP) and a simple genetic algorithm (SGA) solves the reactive planning problem. The problem is divided into operating and planning subproblems; the operating ...
Optimal allocation of distributed generators providing reactive power support ancillary service
(2011-10-05)
Problems as voltage increase at the end of a feeder, demand supply unbalance in a fault condition, power quality decline, increase of power losses, and reduction of reliability levels may occur if Distributed Generators ...
Mixed-integer convex model for VAr expansion planning
(2014-01-01)
This paper presents a mixed-integer convex-optimization-based approach for optimum investment reactive power sources in transmission systems. Unlike some convex-optimization techniques for the reactive power planning ...
Conservative power theory discussion and evaluation by means of virtual instrumentation
(2009-12-01)
Considering different single and multiphase circuits feeding linear and non-linear loads, this paper presents theoretical discussions and experimental evaluation of the recent Conservative Power Theory (CPT), by means of ...
