In this paper, we present a software framework for modeling, simulation, and analysis of critical infrastructure (CI). Our concept fuses together a state-of-the-art telecommunications and electricity distribution system simulator (CI simulator), and a Common Operating Picture visualization system (COP system). The development process included expert interviews, which were conducted to define a comprehensive...
Logic Selectivity immensely reduces both number of outages and their duration in the distribution network. IEC 61850 can be applied for standard implementing of Logic Selectivity in which Generic Object Oriented Substation Events (GOOSE) messages should be exchanged between intelligent field devices over the Internet. However, information security and automation requirements must be noted in order...
Radar cross section (RCS) and inverse synthetic aperture radar (ISAR) are two important application areas for computation intensive RCS tools. Their objective is to control RCS signature in case of different types of mono-static and bistatic radars. To follow the quick development of radar technology, we need more flexible and more accurate RCS calculation tools. In this paper, we introduce CAST application...
Today, electricity distribution and communication networks are getting more tightly integrated as smart grids evolve. From time to time, extreme weather conditions such as severe wind and snow storms cause large outages in electricity distribution networks in Northern countries. Loss of electricity can hinder remote control of grid entities and causes a chain-effect that jeopardizes energy generation,...
Smart Grid companies are looking for communication infrastructure to support remote control, automation, and monitoring. But, these companies are not fully confident in budding LTE technology for M2M (Machine-to-Machine) applications, although it has been proved to be a promising technology for H2H (Human-to-Human) communications. LTE MTC (Machine Type Communications) is a part of the upcoming release...
A reliable and resilient wireless communication technology is needed for Smart Grids. The chosen technology should enable seamless communication between grid devices, applications, consumers, and operators. In addition, it should guarantee adequate network resources for smart grid functions by fulfilling bandwidth, availability, QoS, and latency requirements. Energy companies have been seeking for...
The goal of this paper is to assess the communication latency of operational cellular networks. Latency plays an important role in time-critical smart grid applications. The motivation behind the work was to use cellular networks as communication technology for wireless M2M communications. The latest 3GPP cellular technology, Long Term Evolution (LTE), is considered to be a promising solution for...
Interdependency of mobile communication and electricity distribution networks has increased due to automation and digitalization. Ongoing modernization of grids has motivated energy companies to seek new cost-effective and reliable wireless technologies to enable real-time remote control and monitoring of electricity grids covering vast areas. In contrast to dedicated wireless control systems, commercial...
Traditionally, electricity distribution companies have used private communication networks to control medium-voltage network components such as substations, reclosers, disconnectors, and transformers. Proprietary technologies such as microwave links, narrow band VHF/UHF radios, and private mobile radios were often applied. Today, 3G and 2G cellular packet based networks can provide data connections...
