Determination of the Voltage Stability Index in DC Networks with CPLs: A GAMS Implementation
(Springer, 2019)This paper addresses the voltage collapse analysis in direct-current (DC) power grids via nonlinear optimization approach. The formulation of this problem corresponds to an optimization problem, where the objective function ... -
Hybrid Metaheuristic Optimization Methods for Optimal Location and Sizing DGs in DC Networks
(Springer, 2019)In this paper is proposed a master-slave method for optimal location and sizing of distributed generators (DGs) in direct-current (DC) networks. In the master stage is used the genetic algorithm of Chu & Beasley (GA) for ... -
Optimal power flow in direct-current power grids via black hole optimization
(VSB-Technical University of Ostrava, 2019)This paper addresses the Optimal Power Flow (OPF) problem in DC power microgrids via a combinatorial optimization technique known as Black Hole Optimization (BHO). Such optimization method allows to solve OPF problems via ... -
Power flow approximation for DC networks with constant power loads via logarithmic transform of voltage magnitudes
(Elsevier Ltd, 2019)This paper proposes a logarithmic transformation of voltages (LTVM) for the power flow in DC grids. This problem is non-linear due to the presence of constant power loads (CPLs), which also introduce a negative resistance ... -
Stabilization of MT-HVDC grids via passivity-based control and convex optimization
(Cartagena de Indias, 2021-04-30)This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of ...
