“…Los SSEE se enfrentan a transformaciones y desafíos sin precedentes con la implementación de las smart grids. Este nuevo paradigma ha surgido para construir un sistema de energía eléctrica flexible que coordine mejor los recursos de energía y las cargas, con el objetivo de proporcionar eficientemente el suministro eléctrico de manera sostenible, económica y segura [10]. En la actualidad, el concepto de una estructura operativa y organizacional de la cadena de suministro de electricidad: generación, transmisión y distribución abastecida desde una fuente primaria unidireccional de generación ha cambiado.…”

En la actualidad el posicionamiento de los sistemas de Generación Distribuida (GD) y Microrredes Eléctricas (MREs) han tomado connotadas participaciones alrededor del mundo. Por lo tanto, las necesidades investigativas en torno al control, operación, estabilidad y resiliencia de estos sistemas han marcado un nuevo paradigma de los sistemas de suministro de energía eléctrica. El objetivo de este artículo es mejorar la estabilidad de tensión mediante la inclusión de un dispositivo DSTATCOM de tecnología FACTS en una MRE integrada por GD de tipo Solar Fotovoltaica y Convencional. La metodología desarrollada se aplica en el sistema de prueba de MRE de la CIGRÉ, con la premisa de analizar dos escenarios operativos en relación a la ocurrencia de una contingencia, con lo cual la MRE operará en forma aislada. El análisis se realiza a través de simulaciones dinámicas en el domino del tiempo, donde se analiza y evalúa el comportamiento dinámico de la tensión, después de que los sistemas red-MRE han sido sometidos a perturbaciones, desencadenando la operación en isla eléctrica de la MRE. Los resultados muestran que los modelos y algoritmos de control desarrollados operan satisfactoriamente, además se demuestra la aplicabilidad y beneficios en la instalación de dispositivos FACTS tipo DSTATCOM en sistemas de MREs para mejorar las condiciones operativas en especialmente en términos de estabilidad de tensión.

“…As shown by the closer view in Figure 10b, the open-loop zero z 1 ol and closed-loop pole p 1 ol overlap with each other, while the effect of p 1 ol on system stability and dynamic response is negligible. When K is low (K < K opt ), p 3 cl and p 4 cl are far away from imaginary axis (Re(p 2 cl ) Re {(p 3 cl ),(p 4 cl )}), p 2 cl becomes the dominant closed-loop pole, the system is in an overdamped state. By increasing K until p 2 cl and p 3 cl overlap (this gain value of K is defined as K opt ), the system switches to a state of critical damping (ξ ≈ 1), as shown by "•" in Figure 10a, and the maximal stability and the fastest dynamic response are obtained simultaneously.…”

“…In recent years, distributed power generation system (DPGS) has attracted increasing attention with the aggravation of global energy shortage and environmental issues [1][2][3][4][5]. A typical DPGS is shown in Figure 1; due to the intermittence of renewable energy sources (RESs) such as PV systems and wind turbines, energy storage systems (ESSs) based on battery and supercapacitor are used to suppress power fluctuations, which improves the reliability and quality of power supply.…”

Grid-connected voltage source converters (GC-VSCs) are used for interfacing the distributed power generation system (DPGS) to the utility grid. Performance of the current loop is a critical issue for these GC-VSCs. Recently, reduced order generalized integrator (ROGI)-based current controller is proposed, such that AC reference signal of positive or negative sequences can be separately tracked without steady-state error, which has the advantage of less computational burden. However, the cross-coupling within the ROGI-based current controller would deteriorate the transient response of the current loop. In this paper, a ROGI-based decoupled current controller is proposed to eliminate the coupling between α -axis and β -axis. Thus, the faster dynamic response performance can be achieved while maintaining the merits of ROGI-based current controller. An optimal gain parameter design method for the proposed current controller is presented to improve the stability and dynamic response speed of current loop. Simulation and experiments were performed in MATLAB/Simulink and TMS320C28346 DSP-based laboratory prototype respectively, which validated the proposed theoretical approach.

“…Distributed energy storage systems are used throughout power distribution network to provide flexibility and to compensate for the intermittent nature of renewable DG units, and, in this way, ESSs help increase the penetration of renewable DG units [3]. Moreover, ESSs can help increase energy efficiency and reduce electricity cost by providing energy arbitrage services, i.e., ESSs store energy during low demand (off-peak) periods when electricity cost is low and provide energy during peak demand periods when electricity cost is high [4]. Energy storage systems can also strengthen the resiliency of smart distribution network to power outages due to extreme weather events [4].…”

The massive integration of distributed energy resources in power distribution systems in combination with the active network management that is implemented thanks to innovative information and communication technologies has created the smart distribution systems of the new era. This new environment introduces challenges for the optimal operation of the smart distribution network. Local energy markets at power distribution level are highly investigated in recent years. The aim of local energy markets is to optimize the objectives of market participants, e.g., to minimize the network operation cost for the distribution network operator, to maximize the profit of the private distributed energy resources, and to minimize the electricity cost for the consumers. Several models and methods have been suggested for the design and optimal operation of local energy markets. This paper introduces an overview of the state-of-the-art computational intelligence methods applied to the optimal operation of local energy markets, classifying and analyzing current and future research directions in this area.
