Optimal Capacitor Placement in Unbalanced Electrical Power Distribution Systems through Differential Evolution Algorithm
(2019-09-01)
The problem of optimal capacitor placement (OCP) in three-phase and unbalanced radial distribution systems consists in determining the types, rated power, and in which phases to allocate them, taking into account the ...
A Model-Based Approach for Small-Signal Stability Assessment of Unbalanced Power Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
In this paper, a modeling technique for small-signal stability assessment of unbalanced power systems is presented. Since power distribution systems are inherently unbalanced, due to its lines and loads characteristics, ...
Optimal Restoration/Maintenance Switching Sequence of Unbalanced Three-Phase Distribution Systems
(Ieee-inst Electrical Electronics Engineers Inc, 2018-11-01)
This paper presents a mixed-integer non-linear programming (MINLP) model for the optimal restoration/maintenance switching sequence of unbalanced three-phase electrical distribution systems. Once the protection coordination ...
A Mixed-Integer Linear Programming Model for the Electric Vehicle Charging Coordination Problem in Unbalanced Electrical Distribution Systems
(2015-09-01)
This paper presents a novel mixed-integer linear programming (MILP) model for the electric vehicle charging coordination (EVCC) problem in unbalanced electrical distribution systems (EDSs). Linearization techniques are ...
Increasing the PV Hosting Capacity in Unbalanced Three-Phase Distribution Networks Through Reconfiguration with Closed-Loop Operation
(2021-01-01)
This article presents a novel mixed-integer nonlinear linear programming (MINLP) model to increase the photovoltaic (PV) hosting capacity in unbalanced three-phase electrical distribution systems. The problem considers the ...
An overview of four-leg converters: topologies, modulations, control and applications
(IEEE, 2022)
In three-phase unbalanced systems, where the circulation of zero sequence current is necessary, four-leg converters provide a neutral connection for single-phase or other unbalanced loads typically utilized in three-phase ...
Evaluation of Volts/Hertz and over-excitation limiters acting under unbalanced load conditions.
(IEEEPiscataway, 2013)
Currently, a worldwide tendency of decentralization
of electric energy production (called Distributed Generation) is
observed, where small generators – sometimes composed by
synchronous machines – are connected mainly ...
Critical evaluation of FBD, pq and CPT current decompositions for four-wire circuits
(2009-12-01)
This paper investigates the major similarities and discrepancies of three important current decompositions proposed for the interpretation of unbalanced and/or non linear three-phase four-wire circuits. The considered ...

Software Sensor-Based STATCOM Control under Unbalanced Conditions
(Institute of Electrical and Electronics Engineers, 2009-07-24)
A new control strategy for static compensators (STATCOMs) operating under unbalanced voltages and currents is presented in this paper. The proposed strategy adopts a state observer (software sensor) to estimate ac voltages ...
