Numerical methods for power flow analysis in DC networks: State of the art, methods and challenges
(2020-12)
This study addresses the power-flow-analysis problem for direct-current (DC) grids from a numerical perspective. Classical and emerging algorithms for power flow solutions in DC networks such as Gauss--Seidel, successive ...
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 ...
On the Conic Convex Approximation to Locate and Size Fixed-Step Capacitor Banks in Distribution Networks
(2022-02-20)
The problem of the optimal siting and sizing of fixed-step capacitor banks is studied in
this research from the standpoint of convex optimization. This problem is formulated through a mixed-integer nonlinear programming ...
A successive approximations method for power flow analysis in bipolar DC networks with asymmetric constant power terminals
(2022-07-02)
This paper deals with the power flow problem in bipolar direct current distribution networks with unbalanced constant power loads. The effect of the neutral wire is considered in two prominent cases: (i) when the system ...
Minimization of the distribution operating costs with D-STATCOMS: A mixed-integer conic model
(2022-07-22)
This paper addresses the problem of determining the optimal location and operation of distribution static synchronous compensators (D-STATCOMs) in power distribution networks. Metaheuristic algorithms have been conventionally ...
Stabilization of MT-HVDC grids via passivity-based control and convex optimization
(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 ...
Passivity-based control of islanded microgrids with unknown power loads
(2020-10-12)
In this paper, the control problem of microgrids (MGs)operating in islanded mode is approached from a passivity-based control perspective. A control scheme is proposed that, relying only on local measurements for the power ...
Power Flow in Bipolar DC Distribution Networks Considering Current Limits
(2022-09)
Power electronics converters are equipped with current controls that protect the converter from over-currents. This protection introduces non-differentiable equations into the power flow problem. The conventional Newton's ...
