Maniobras de llenado y vaciado en grandes conducciones. Aplicación a una tubería de fundición DN400 en Massamagrell (Valencia, España)
(2020-01-31)
Air pockets inside hydraulic installations during filling and emptying processes can generate pressure surges and negative pressure, respectively. Serious damages can be occurred in pipelines. In order to analyse hydraulic ...
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 ...
2D CFD Modeling of Rapid Water Filling with Air Valves Using OpenFOAM
(2021-11-04)
The rapid filling process in pressurized pipelines has been extensively studied using mathematical models. On the other hand, the application of computational fluid dynamics models has emerged during the last decade, which ...
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 ...
Assessment of Steady and Unsteady Friction Models in the Draining Processes of Hydraulic Installations
(2021-07-08)
The study of draining processes without admitting air has been conducted using only steady friction formulations in the implementation of governing equations. However, this hydraulic event involves transitions from laminar ...
A generalized passivity-based control approach for power compensation in distribution systems using electrical energy storage systems
(Elsevier Ltd, 2018)
This paper presents a generalized interconnection and damping assignment passivity-based control (IDA-PBC) for electric energy storage systems (EESS) such as: superconducting magnetic energy storage (SMES) and supercapacitor ...
Indirect IDA-PBC for active and reactive power support in distribution networks using SMES systems with PWM-CSC
(Elsevier Ltd, 2018)
In this paper an indirect interconnection and damping assignment passivity-based control (IDA-PBC) applied to the three-phase superconducting magnetic energy storage systems (SMES) is proposed to support active and reactive ...
DERs integration in microgrids using VSCs via proportional feedback linearization control: Supercapacitors and distributed generators
(Elsevier Ltd, 2018)
This paper presents an exact feedback linearization control strategy for voltage source converters (VSCs) applied to the integration of distributed energy resources (DERs) in smart distribution systems and microgrids. ...
A Potential Function for the Power Flow in DC Microgrids: An Analysis of the Uniqueness and Existence of the Solution and Convergence of the Algorithms
(Springer New York LLC, 2019)
The power flow equations in DC microgrids are nonlinear due to the presence of constant power terminals. In this context, a rigorous demonstration of the convergence and uniqueness of the solution for Newton’s method is ...
Nonlinear Analysis for the Three-Phase PLL: A New Look for a Classical Problem
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper we investigate the dynamics of the classic synchronous reference frame phase-locked-loop (PLL) from a non-linear perspective. First, we demonstrate the nonlinear differential equations that describe the PLL ...
