Resilience of a distribution system can be enhanced by efficient restoration critical load following major outage. Existing models include optimization approaches that consider available information without incorporating the inherent asynchrony data arrival during execution plan. Failure to asynchronous nature lead underutilization resources. Moreover, analytical become computationally inefficient for large scale systems. On other hand, artificial intelligence (AI)-based tools have...
Opportune fault location in power distribution systems is an important aspect related to quality, and especially maintain good continuity indexes. Fault methods which use more information than RMS values of voltage current, are the commonly known as knowledge based - KBM. Those require a complete database adequately perform training validation stages, consequence successfully task. In this paper, modeling system its protective relaying obtain extensive using capabilities ATP Matlab...
Increasing penetration of proactive agents, including distributed energy resources (DERs) and responsive loads (RLs), in distribution systems motivates methods to incentivize market participation from demand-side resources. The complexity resulting large-scale integration agents has challenged the viability centrally managing grid a system environment motivated decentralized frameworks coordinate transactions. Existing are primarily focused on designing transaction mechanisms. They neither...
The increasing penetration of proactive agents in electric power distribution systems calls for mechanisms to coordinate their trading activities. commonly employed centralized and distributed methods supply-demand coordination are not only limited by hardware requirements but also restrictive active participation the market agents. This paper proposes a novel decentralized transactive framework that allows participants bid clear transactions via bilateral interaction process. is based on 1)...
At Washington State University, a modern cyber-physical system testbed has been implemented based on an industry-grade distribution management (DMS) that is integrated with remote terminal units, smart meters, and solar photovoltaic array. In addition, the real model from Avista Utilities in Pullman, WA, modeled DMS. The proposed environment allows students instructors to utilize these facilities for innovations learning teaching. For power engineering education, this helps understand...
Resiliency of distribution systems under extreme operating conditions is critical, especially when the utility not available. With large-scale deployment distributed resources, it becomes possible to restore critical loads with local non-utility resources. Distribution system operators (DSOs) need determine be restored, considering limited resources and facilities. Several studies on resiliency have been conducted for restoration systems. However, inherent asynchronous characteristic...
La localización de fallas en sistemas distribución es gran importancia para la calidad del servicio energía eléctrica, especialmente lo relacionado con continuidad suministro. Para localizar se usan comúnmente dos tipos métodos, los basados el modelo y conocimiento. Los métodos conocimiento información las señales tensión corriente registradas durante falla, normalmente requieren cantidad datos desarrollar adecuadamente su función. Este artículo presenta forma modelar protecciones un sistema...
The current regulatory framework demands better quality service to electric utilities, using as a measure of non scheduled power outages the SAIDI and SAIFI indexes. In this paper, selection characteristics from protective relays set support vector machines (SVM) is proposed in order solve fault location problem distribution systems. To show effectiveness methodology, large scale system was used. Results lower validation errors which are associated high performance. Opportune systems plays...
Globally, the number of electric vehicles (EVs) continues to increase. This on-going trend poses challenges for power distribution systems. The inclusion vehicle supply equipment (EVSE) should be compatible with a changing energy system, whose structure is becoming increasingly distributed. impact future EVs analyzed and considered in system planning upgrades. In this study, analysis conducted utility company U.S. West Coast. Real data feeders converted into GridLAB-D model running flow...
The Information and Communications Technology (ICT) for control monitoring of power systems is a layer on top the physical system infrastructure.The cyber components form tightly coupled Cyber-Physical System (CPS).Sources vulnerabilities arise from computing communication cyber-power grid.Cyber intrusions targeting grid are serious threats to reliability electricity supply that critical society economy.In typical environment, numerous attack scenarios have shown how unauthorized users can...
The power grid is being transformed from a system with centralized fossil-fuel-based generation and passive customers into the one large-scale deployment of distributed energy resources (DERs) proactive customers. At distribution level, decentralized market constructs have been proposed; however, these methods are not well suited for coordination large number DERs responsive loads. In this paper, bilateral Transactive Energy framework developed to manage participants' trading activities....
