Stability Analysis of Single-Phase Low-Voltage AC Microgrids with Constant Power Terminals
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief presents the stability analysis of single-phase microgrids (SP-MG) operating under master-slave connection with constant power terminals. The SP-MG is composed of linear elements, nonlinear loads, and ...
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 ...
A parametric sensitivity analysis of numerically modelled piston-type filling and emptying of an inclined pipeline with an air valve
(BHR Group Limited, 2018)
Filling and emptying operations should be planned by engineers in operational stages to prevent a system failure depending on reaching extreme low pressure values. In this sense, a compression of an air pocket produces ...
Hydraulic modeling during filling and emptying processes in pressurized pipelines: a literature review
(Taylor and Francis Ltd., 2019)
Filling and emptying processes are common maneuvers while operating, controlling and managing water pipeline systems. Currently, these operations are executed following recommendations from technical manuals and pipe ...
Computational fluid dynamics for sub-atmospheric pressure analysis in pipe drainage
(Taylor and Francis Ltd., 2019)
The occurrence of sub-atmospheric pressure in the drainage of pipelines containing an air pocket has been known as a major cause of several serious problems. Accordingly, some system malfunction and pipe buckling events ...
