In this paper, we propose a game theoretic modelling paradigm for the energy trading market of a Microgrid Social Network (MGSN) architecture in which the networked Microgrids (MGs) are connected by a common physical bus and social networks. In the considered MGSN, individual MGs involved in energy trading, called market participants, make decision on energy trading based on the state estimation of...
The paper presents an indoor testbed evaluation of a multi-hop IEEE 802.15.4e Time Slotted Channel Hopping (TSCH) sensor network, operating in 2.4 GHz band. First goal of the evaluation is to assess the perspectives of TSCH, as a more reliable version of IEEE 802.15.4, for meter reading applications in a Smart Grid. Secondly, we compare the network performance for two medium access schemes: contention-based...
Deep integration of information and communication technology (ICT) brings insecure risk to power system operation. A risk assessment approach of power grid considering the reliability of information system was presented. The influence of information system on the action of protection was analyzed firstly. The reliability model of information system was established. Then the evaluation index, including...
There is a growing interest by power system operators to encourage load resources to offer frequency regulation. There are several studies that evaluate the system-wide benefits of such load resource participation. However, the current literature often overlooks the potential adverse impact on power distribution feeders. This paper seems to address this open problem. We focus on a scenario where load...
This paper presents a new approach to obtain an optimal energy management in Smart Grids from both generation and demand sides where generation and demand units collaborate with others in a distributed manner to simultaneously obtain their optimal powers that maximize the total welfare in the grid. The proposed approach is developed based on an optimization method called Alternating Direction Method...
In this paper, a novel random access mechanism is introduced to enable the integration of smart grid distribution automation (DA) services in public LTE networks. The smart grid paradigm is anticipated to improve grid reliability through extensive and timely information exchange in the power distribution network. LTE appears as a promising communication technology for advanced distribution grid services...
One of the major challenges of the future power systems is managing the substantial unreliability and unpredictability induced by the large share of renewables. As one of the promising solutions, energy cooperatives have recently drawn attention. Unlike most of the existing proposed strategies (e.g., storage), there is not much known yet about the practical importance of energy cooperatives. Taking...
The electrical grid uses intelligent electronic devices, communication technologies, distributed energy resources, energy storage, and smart appliances in order to make smart grid which provides reliability and power quality. In smart grid, Advanced Metering Infrastructure (AMI) provides a two-way communication system between utilities and smart meters, as well as the ability to modify consumer demand...
To increase the maximum possible benefits of technical, economic and environmental aspects, the optimal sizing and sitting of distributed generation in distribution system has always been challenging for customers as well as to utilities. The objective of optimum sitting of distributed generation in a distribution system is to reach suitable operation of such systems with minimization losses of the...
Development in the field of electronics and communication set up new paradigm. The need of making the grid smart is increasing due to environmental constrain and effective use of the available electricity. The use of digital information and controls technology to improve reliability, security, and efficiency of the electric grid.
The existing urban distribution networks (DN) in Russia are characterized by hierarchical radial trunk constructing principle with unidirectional energy distribution. The main disadvantages of the network: high electricity losses, disordered construction of network in cities, poor connectedness and manageability of load nodes, difficulties in integration of renewable energy sources. The question of...
Deregulation and the massive growth of Distributed Generation (DG) in distribution networks are forcing the network operators to improve the operational efficiency and power quality at the distribution level. Distribution Automation (DA) enables operators to monitor and control various distribution system components and thus decrease the restoration time after a fault occurs. To implement DA properly,...
Smart grid can be viewed as a modern electric power grid infrastructure with enhanced reliability, flexibility and efficiency that is achieved through automated control of production and distribution of electric power, modern communications infrastructure, smart monitoring devices, and renewable energy resources. New features introduced by smart grid means that substation communication is more complex...
This paper aims to determine and identify the best technical placement for fault locators — FLs — on the distribution network, in order to improve the reliability in the system. The international indices such as SAIFI and SAIDI are evaluated in two scenarios; the first one analyze the power system in its current configuration whereas the second one assumes that FLs are installed in different places...
To meet different communication requirements, a smart grid communication framework based on a hybrid network has been widely used. Virtual networks are established for various types of services respectively, and are embedded into heterogeneous substrate networks. Based on the framework, wireless network virtual mapping algorithm based on particle swarm optimization is proposed. In this scheme, the...
The core vision of the smart grid concept is the realization of reliable two-way communications between smart devices (e.g., IEDs, PLCs, PMUs). The benefits of the smart grid also come with tremendous security risks and new challenges in protecting the smart grid systems from cyber threats. Particularly, the use of untrusted counterfeit smart grid devices represents a real problem. Consequences of...
