Passivity-Based Control for Hydro-Turbine Governing Systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper an interconnection and damping assignment passivity-based control (IDA-PBC) applied to the hydro-Turbine governing systems (HTGS) is proposed to regulate the relative deviation of turbine speed in single ...
SCES Integration in Power Grids: A PBC Approach under abc, αβ0 and dq0 Reference Frames
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents an integration of three-phase supercapacitor energy storage (SCES) in power grids via passivity-based control (PBC) theory under different reference frames. The SCES systems have the possibility to ...
VSC with direct PI power control for frequency compensation in a microgrid: A PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2019)
The power systems with low inertia such as microgrids require advanced control strategies to improve their performance. These type of grids use voltage source converters to interconnect renewable energy sources and storage ...
Wirtinger's Calculus for the Load Flow in Power Distribution Grids
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper shows a Wirtinger's-Calculus based loadflow methodology for power distribution grids. This approach allows to obtain an algorithm which works directly on the complex domain maintaining some useful symmetries and ...
Small-Signal Stability in Low-Voltage DC-Grids
(Institute of Electrical and Electronics Engineers Inc., 2018)

On the Matricial Formulation of Iterative Sweep Power Flow for Radial and Meshed Distribution Networks with Guarantee of Convergence
(2020-08-21)
This paper presents a general formulation of the classical iterative-sweep power flow, which is widely known as the backward–forward method. This formulation is performed by a branch-to-node incidence matrix with the main ...
PI-PBC Approach for Voltage Regulation in Cuk Converters with Adaptive Load Estimation
(2020-11-25)
This paper proposes a proportional-integral passivity-based controller (PI-PBC) for supporting voltage in linear loads integrated with Ćuk converters. An adaptive load estimator is also employed to avoid current measurements ...
A quadratic convex approximation for optimal operation of battery energy storage systems in DC distribution networks
(2021-11-07)
This paper proposes a quadratic convex model for optimal operation of battery energy storage systems in a direct current (DC) network that approximates the original nonlinear non-convex one. The proposed quadratic convex ...
A Convex OPF Approximation for DC Networks Considering Voltage-Dependent Load Models
(2020-12-01)
This paper addresses the problems of power flow and optimal power flow analysis considering voltage-dependent load models from the convex point of view. First, Taylor series expansion method is employed for linearizing the ...
Voltage stability margin in DC grids with CPLs: A recursive Newton-raphson approximation
(2019-03-11)
This express brief addresses the voltage collapse problem in direct-current (dc) networks by using a recursive heuristic search algorithm based on the Newton-Raphson method. The determinant of the Jacobian matrix in the ...
