Introducción – La competitividad de las empresas está basada en la efectividad de sus procesos medidos en eficacia y eficiencia. Es bajo esa premisa que la gestión de activos aparece como una estrategia primordial dentro del modelo de negocio. De esa manera, la gestión de activos se convierte en un modelo colaborativo en los diferentes niveles de la organización y así lo han entendido los entes regulatorios de los países quienes entienden que una infraestructura avanzada es uno de los pilares del desarrollo económico (Balzer & Schorn,
2015). Las últimas directrices y resoluciones emitidas por la Comisión de Regulación de Energía y Gas (CREG) apuntan a ese objetivo estratégico de país, ya que la tarea de un país eficiente es renovar su infraestructura existente sólo cuando ésta ha alcanzado su ciclo de vida logrando así prosperidad para las empresas y para la población. La estructura del suministro de energía está en plena etapa de modernización, si se supone que la edad promedio de los equipos es de 40 años, está claro que en los próximos años se espera que la infraestructura existente integre nuevas tecnologías para controlar la confiabilidad y la seguridad
del suministro de energía. La llamada “red inteligente” se ha vuelto muy importante en el desarrollo de sistemas de infraestructura y en todo momento se presenta como una solución para todos los problemas futuros de suministro de energía.
Abstract – La transformación de los sistemas de energía en sistemas inteligentes y controlados es una tendencia mundial que se ha venido desarrollado al interior de los campus universitarios. Universidades alrededor del mundo han dispuesto sus instalaciones para la implementación de redes inteligentes con el objetivo de dar a conocer un ambiente completamente funcional de las Smart-Grids y demostrar la amplia aplicabilidad que ´estas tienen. Este documento describe la implementación de una plataforma de gestión energética en tiempo real al interior del campus de la Universidad Nacional de Colombia – sede Bogotá. Su implementación es llevada a cabo como parte del proyecto de investigación titulado “Laboratorio Nacional de Redes Inteligentes en el Campus Universitario lab+i”. El desarrollo de esta plataforma tiene como objetivo dotar al campus universitario de una infraestructura que permita la integración de las diferentes tecnologías y elementos que hacen parte de una Smart Grid, así como establecer una metodología de pruebas, tanto de software como de hardware, para la evaluación de la funcionabilidad y desempeño de estas tecnologías como conjunto. Para lograr esto se hace necesario contar con sistemas de medida, de comunicación, de almacenamiento de información y de análisis lo suficientemente abiertos, que permitan la integración de cualquier tipo de tecnología o equipo sin importar sus características particulares.
Abstract— The increasing penetration of Decentralized Generation (DG) among other factors rises the essential need to adapt and plan the distribution systems in an optimal way to achieve an appropriate cost-efficient development of networks to be prepared for the future grid development. This paper analyzes the impact to using higher nominal voltage levels in distribution networks to improve the hosting capacity of the network, its performance, and at the same time reducing network losses.
Through a repetitive process for different scenarios proposed, the benefits of the voltage level increase for an IEEE test network were determined. Three voltage levels (13.2kV, 20kV and 24,9kV) were analyzed starting with a base case and different variations to simulate practical cases respecting voltage limits and capacities of the elements. DG location, DG capacities, DG integration levels were also considered as part of the Hosting Capacity calculation.
Using equivalent grid characteristics, this work compares also the performances of overhead networks (OHL) and networks using underground cables for the various scenarios in order to analyze further improvements which are part of distribution networks in Europe.
Conclusions and recommendations for the planning stage of these improvements are also presented.
This is a preview about the Inter-Area Oscillations in the 500-kV Vietnamese Power System. If you are interesting regarding its full paper please contact us: info@neplan.ch
Abstract— The paper presents the study of the 500-kV Vietnamese power system. The oscillatory response of the system is analyzed both with a modal analysis and a time domain analysis. The 500-kV system of Vietnam is modeled in details, including all the power plants with the corresponding regulators. The model is developed in collaboration with the Institute of Energy Science IES-VAST of Vietnam and it is validated with the data provided by the National Load Dispatch Centre (NLDC) of Vietnam. The simulation results reveal a clear identification of potential inter-area oscillations between North and South of the Country. A worsening of the observed phenomenon should be considered as possible, especially in the perspective of the new installation of a significant amount of power from renewable sources into the Vietnamese system.
This is a preview about the Inertial response of isolated power networks. If you are interesting regarding its full paper please contact us: info@neplan.ch
Abstract— The constant increase of power generation provided by renewable energy source (RES) power plants is causing a progressive reduction of the overall inertia of the power systems. Especially in the case of small, isolated power networks, the replacement of conventional generation plants with RES power plants can affect significantly the frequency response of the system. The critical low-inertia conditions can be improved by the introduction of specific additional controls to the RES power converters. These control schemes are known as “synthetic inertia” or “virtual inertia” controls. The paper analyzes the impact of a derivative-based inertial control on a small, isolated power system, with a relevant share of power supplied by a wind power plant. The inertial response control is added to the standard IEC wind turbine active power controller of type WT4A. Simulations performed on the dynamic model of the system indicate the appearance of frequency oscillations in response to the applied power unbalance. A comprehensive analysis of the observed phenomenon is given, and a tuning of the inertial control parameters is then proposed. Simulations repeated with the proposed tuning of the controller prove the validity of the applied modifications, and show a satisfactory transient response of the system, even in the case of critical low-inertia conditions.
This is a preview about the Impact of Converter-Interfaced Generation to the Frequency Response of the European Power. If you are interesting regarding its full paper please contact us: info@neplan.ch
Abstract—The increase of converter-interfaced generation (CIG) typically related to renewable energy sources is progressively causing a significant change of power systems operation. The curtailment of synchronous generation with the consequent reduction of the overall kinetic energy is one of the related issues, currently under investigation in academia and industry. The work considers the problem of overall inertia reduction from a large-scale point of view, analyzing the impact of different CIG integration levels to the frequency response of the power system of Continental Europe. The kinetic energy is evaluated for each country of the synchronous area, and the system is modified substituting conventional synchronous generation with converter-interfaced generation. The models of power converters and corresponding controls follow typical representation for stability studies: they are modeled as controlled current sources with active and reactive power control loops, implemented as user-written equations within the overall mathematical model of Continental Europe power system. Comprehensive time-domain simulations are performed for each scenario, assuming the system subjected to a power plant outage: the obtained frequencies for Western, Central and Eastern Europe are reported, and typical frequency metrics are used to evaluate the response of the system across the different scenarios. Results show how the penetration of CIG affects the frequency response of the system, in terms of instantaneous frequency deviation and maximum frequency rate. A significant change in the inter-area oscillations is also observed, with a progressive increase of the oscillation frequency of the East-West mode, as confirmed by the modal analysis of the system.
This is a preview about the WT Type 4 Benchmarks for IEC 61400-27-1. If you are interesting regarding its full paper please contact us: info@neplan.ch
Abstract – Since several years there has been a constant effort at international level for the standardization and the validation of different types of wind turbine (WT) dynamic models. The paper focuses on the IEC 61400-27-1 type 4 model, proposing and fully describing two benchmark systems for the assessment of dynamic performance. The first system is a simple setup and it is designed to specifically assess the transient response of the WT controls. The second system is based on the IEEE 9-bus test system, and it is a multi-machine configuration allowing for the inclusion of the typical power system dynamics of synchronous machines and corresponding primary regulators. System configurations, models and parameters are designated with the purpose of interoperability and replicability, aiming to models comparison and validation.
Due to incentive-based regulation and in particular the amendment from 2016, distribution system operators in Germany face increasing cost pressures. Structured asset management can be used as the foundation for a cost efficient use of the grid equipment. As part of this paper, a methodology will be presented for combination of strategic and operative elements of asset management in a holistic investment schedule. On the one hand, the main building block is strategic network planning for identifying the need for action based on future supply tasks, and on the other a structured assessment of the condition of current network equipment. This paper focuses on the methodology and results of the strategic network planning. The methodology for deriving an investment schedule based on status and strategy indices was applied to the distribution grid of Stadtwerke Ratingen GmbH.
