“…The mathematical model defined from ( 1) to ( 8) has the following interpretation [22,50]: the objective function (1) quantifies the total greenhouse emissions produced by the diesel generators during their operation; in (2) is presented the power balance equation per node, which is typically known as power flow constraint, this being a non-affine constraint. Expression (3) shows the calculation of the current flow through ijth branch as a function of the voltage drop; in (4) is defined the box constraint related with the power capabilities in the diesel generators; in (5) the thermal bounds of the network conductors are presented in Amperes; meanwhile, ( 6) defines the voltage regulation bounds of the grid, which are defined by regulatory entities. Expression ( 7) determines the possibility of locating a PV generator in the network by defining its maximum ranks admissible for a generation.…”

“…Recent deployments of power electronics have allowed the positive advancement and development of efficient renewable energy interfaces for wind and photovoltaic plants [1][2][3], and the large-scale usage of energy storage systems, such as batteries [4][5][6], supercapacitors [7,8], superconductors [3,9,10] and flywheels [11,12]. These devices can be integrated into the power system using different interface technologies; i.e., to operate in the classical alternating current (AC) or direct current (DC) grids [3,13]. The selection of the grid operative condition plays an important role in the quality of the electrical service provided to the end-users.…”

This paper addresses the problem of the optimal location and sizing of photovoltaic (PV) sources in direct current (DC) electrical networks considering time-varying load and renewable generation curves. To represent this problem, a mixed-integer nonlinear programming (MINLP) model is developed. The main idea of including PV sources in the DC grid is minimizing the total greenhouse emissions produced by diesel generators in isolated areas. An artificial neural network is employed for short-term forecasting to deal with uncertainties in the PV power generation. The general algebraic modeling system (GAMS) package is employed to solve the MINLP model by using the CONOPT solver that works with mixed and integer variables. Numerical results demonstrate important reductions of harmful gas emissions to the atmosphere when PV sources are optimally integrated (size and location) to the DC grid.

“…Las redes de distribución de energía eléctrica son consideradas como un elemento esencial en la vida de los seres humanos ya que, a partir de su aparición, estas se han convertido en en un factor fundamental para el desarrollo económico y social en centros urbanos y zonas rurales aledañas a estos (Abu-Rub et al 2014;Ellabban et al 2014;Montoya et al 2019b;Parhizi et al 2015). Sin embargo, las comunidades que se encuentran alejadas de las redes eléctricas convencionales, se ven relegadas a un segundo plano sin la posibilidad de acceso a tecnología, redes de comunicación o Internet; incluso en algunos casos sufren la ausencia de servicios esenciales como salud y educación, los cuales son derechos fundamentales y que hacen parte de una vida digna (Bueno-Lopez and Garzon Lemos 2017).…”

“…En la literatura científica se han propuesto diferentes alternativas para la generación de tensión en redes aisladas monofásicas considerando fuentes de generación de energía renovable y sistemas de almacenamiento de energía mediante convertidores fuente de tensión y filtros LC (Talbi et al 2020). Algunos de estos trabajos se revisan a continuación: En (Montoya et al 2019b) y (Montoya et al 2019a) se presentó el diseño de controladores basados pasividad mediante PI-PBC e IDA-PBC para redes monofásicas aisladas con presencia de sistemas de almacenamiento de energía con supercapacitores, superconductores y baterías, además de fuentes renovables fotovoltaicas y eólicas. La ventaja de estos diseños es la garantía de estabilidad en lazo cerrado mediante la formulación de funciones Hamiltonianias de energía y el teorema de estabilidad de Lyapunov.…”

This paper addresses the problem of sinusoidal voltage generation in linear loads using a voltage source inverter (VSI). The port-Hamiltonian structure in open-loop is used to design a passivity-based controller with proportional-integral gains (PI-PBC) in order to develop the control strategy. The main advantage of using passivity-based controllers corresponds to the possibility of guaranteeing asymptotic stability by transforming the trajectory tracking problem into a regulation control one. In addition to the PI-PBC, a linear load estimator is employed based on an integral formulation to determine the value of the equivalent conductance in the load, which reduces the number of current sensors. Numerical validations demonstrate that the sinusoidal voltage provided by the VSI to the load has a tracking error lower than $1~\%$, with harmonic distortions lower than $2.6~\%$, both for voltage and currents in the load. All the simulations were conducted in MATLAB/Simulink using the SimPowerSystems library version 2017a.

“…A big attention has been given to robust control strategies and robustness analysis by developing various techniques to manage bounded system uncertainty. The sliding mode control (SMC), 14 the linear matrix inequality (LMI) 15 approach and the passivity-based control (PBC) approach 16–18 are among the best-known robust control techniques.…”

This article introduces a unified Hamiltonian formulation for controlling grid-connected direct current microgrid via interconnection and damping assignment–passivity-based control. The direct current microgrid includes hydro–solar–wind hybrid renewable energy systems and battery/supercapacitor hybrid energy storage system. Hybrid renewable energy systems are integrated as a disturbed direct current source, while hybrid energy storage system is integrated via semi-active topology, where the battery is connected to the direct current bus through a bidirectional dc-to-dc converter. The proposed Hamiltonian approach allows us to design a control strategy for the bidirectional dc-to-dc converter and the grid-connected three-phase inverter to (1) reject power disturbances in the direct current bus via the supercapacitor and ensure smooth current in the battery as well as in the grid and (2) assign the system to a desired equilibrium after sharp changes. In the studied article, the stability of the system under the interconnection and damping assignment–passivity-based control controller is investigated. The interconnection and damping assignment–passivity-based control controller is compared with two conventional proportional–integral–based controllers through simulations under the MATLAB/Simulink environment. The main contributions in this article are the unified hybrid modelling for dc-to-dc power converter and grid-connected inverter using port-Hamiltonian approach, external disturbance rejection in the multi-source power system using interconnection and damping assignment–passivity-based control, and the assurance of global asymptotic stability of the closed-loop system.
