A Sequential Quadratic Programming Model for the Economic-Environmental Dispatch in MT-HVDC
(Institute of Electrical and Electronics Engineers Inc., 2019)This paper addresses the economic-environmental dispatch problem for thermal plants on a Multi-terminal HVDC power grid. A multi-objective optimization approach is used for modeling the compromise between fuel costs and ... -
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 ... -
On the Existence of the Power Flow Solution in DC Grids With CPLs Through a Graph-Based Method
(Cartagena de Indias, 2020-08-27)This brief explores the formulation of the power flow problem in DC grids with a classical incidence matrix through a graph-based formulation. This corresponds to a compact representation of the conventional backward/forward ... -
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 ... -
Relaxed convex model for optimal location and sizing of DGs in DC grids using sequential quadratic programming and random hyperplane approaches
(Elsevier Ltd, 2020)This report addresses the problem of optimal location and sizing of constant power sources (distributed generators (DGs)) in direct current (DC) networks for improving network performance in terms of voltage profiles and ...
