A mixed-integer convex model for the optimal placement and sizing of distributed generators in power distribution networks
(2021-01-11)
The optimal placement and sizing of distributed generators is a classical problem in power distribution networks that is usually solved using heuristic algorithms due to its high complexity. This paper proposes a different ...
A mixed-integer conic formulation for optimal placement and dimensioning of DGs in DC distribution networks
(2021-01-14)
The problem of the optimal placement and dimensioning of constant power sources (i.e., distributed generators) in electrical direct current (DC) distribution networks has been addressed in this research from the point of ...
On the convergence of the power flow methods for DC networks with mesh and radial structures
(2021-02)
The convergence analysis of the power flow methodologies for direct current (dc) electrical networks is addressed in this paper. The Banach fixed-point theorem is employed to prove the convergence and uniqueness in the ...
Simultaneous Minimization of Energy Losses and Greenhouse Gas Emissions in AC Distribution Networks Using BESS
(2021-04-22)
The problem of the optimal operation of battery energy storage systems (BESSs) in AC grids is addressed in this paper from the point of view of multi-objective optimization. A nonlinear programming (NLP) model is presented ...

Latencies in power systems: A database-based time-delay compensation for memory controllers
(2021-01-18)
Time-delay is inherent to communications schemes in power systems, and in a closed loop strategy the presence of latencies increases inter-area oscillations and security problems in tie-lines. Recently, Wide Area Measurement ...
A linearized approach for the electric light commercial vehicle routing problem combined with charging station siting and power distribution network assessment
(2021-05-21)
Transportation electrification has demonstrated a significant position on power utilities and logistic companies, in terms of assets operation and management. Under this context, this paper presents the problem of seeking ...
Approximated Mixed-Integer Convex Model for Phase Balancing in Three-Phase Electric Networks
(2021-08-31)
With this study, we address the optimal phase balancing problem in three-phase networks
with asymmetric loads in reference to a mixed-integer quadratic convex (MIQC) model. The objective
function considers the minimization ...
