Integrated Methodology for the Planning of Electrical Distribution System Considering the Continuity of the Service and the Reduction of Technical Losses
(Springer, 2019)
This article presents a methodology that allows to obtain an optimal plan of re-configuration of the local distribution system to 13.2 kV, considering the improvement in the continuity of the service to the users and the ...
Direct power control for VSC-HVDC systems: An application of the global tracking passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control (DPC) for a high-voltage direct-current system using voltage source converters (VSC-HVDC) by applying passivity-based control theory. This system allows doing an efficient and ...
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 ...
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 ...
Heuristic approach for optimal location and sizing of distributed generators in AC distribution networks
(World Scientific and Engineering Academy and Society, 2019)
This paper addresses, from a heuristic point of view, the problem of the optimal location and sizing of distributed generators (DGs) in alternating-current distribution networks with radial topology. A master–slave ...
Integration of energy storage systems in AC distribution networks: Optimal location, selecting, and operation approach based on genetic algorithms
(Elsevier Ltd, 2019)
This paper presents a method to find the optimal location, selection, and operation of energy storage systems (ESS- batteries-) and capacitors banks (CB) in distribution systems (DS). A mixed-integer non-linear programming ...
Numerical Approximation of the Maximum Power Consumption in DC-MGs with CPLs via an SDP Model
(Institute of Electrical and Electronics Engineers Inc., 2019)
This brief addresses the numerical approximation of the maximum power consumption in direct-current microgrids (DC-MGs) with constant power loads through a convex optimizing model. The convex formulation is developed via ...
Sequential quadratic programming models for solving the OPF problem in DC grids
(Elsevier Ltd, 2019)
In this paper, we address the optimal power flow problem in dc grids (OPF-DC). Our approach is based on sequential quadratic programming which solves the problem associated with non-convexity of the model. We propose two ...
Optimal power dispatch of DGS in DC power grids: A hybrid gauss-seidel-genetic-algorithm methodology for solving the OPF problem
(World Scientific and Engineering Academy and Society, 2018)
This paper addresses the optimal power flow (OPF) problem in direct current (DC) power grids via a hybrid Gauss-Seidel-Genetic-Algorithm methodology through a master-slave optimization strategy. In the master stage, a ...
