The evaluation of intelligent transformation level of primary equipment in substation is an important part of the second batch of intelligent substation pilot project. In this paper, pilot projects for the transformation of smart substations in several regional power grids are extensively investigated, of which the following work is done on the basis: Firstly, the evaluation model of intelligent transformation...
The paper presents the impact of connecting Renewable sources to the Smart Grid with regard to improving Power Quality aspects. The impact of integrating renewable sources on Power Quality indices in the grid wes analyzed and the measures for avoiding the negative impact are included in the paper. Challenges coming from the integration of renewables – variability and uncertainty and the correlation...
In the near future Smart Grid will be able to monitor and control key elements in the generation, transmission and distribution of energy to the end-user. This concept is in full development, but it will take a lot of time to achieve "maturity". Activities like consumer education, development of standards, technology improvement need to be carried out so that the concept of Smart Grid takes...
In this article are analyzed and discussed what should be the rules that must be applied in Chile to deploy the smart grid. It examines what kinds of standards can be applied in various systems of the mains: in the generation, transmission and distribution are the characteristics of the rules for the transmission of data. It analyzes the characteristics of the network of smart meters, and there are...
Conventional electricity grids evolve into smart grids by incorporating Information and Communications Technology (ICT) services. These services are meant to provide finegrained monitoring of the grid and pervasive control over its components. The ultimate goal is to avoid major failures and blackouts and to improve the efficiency of energy generation, transmission, and consumption. Smart grids support...
Power quality is one of the important challenges for the smart distribution grids. It is not possible to know the state of power quality in the network without appropriate measurements or monitoring. As an answer to need for power quality monitoring in smart distribution grids, this paper further develops the Integrated Power Quality Monitoring System (IPQMS). IPQMS integrates power quality data from...
The integration of Trusted Network Connect (TNC) enhances the overall security of the German Smart Metering System. For that reason, the research project SPIDER has described a concept to integrate TNC into the German Smart Metering System. However, the project has discovered contradictions between the standards, which are defined for the German Smart Metering System and the standards that describe...
In response to the EU Mandate M/490, two crucial tools were developed for supporting the standardization of the Smart Grid: the Smart Architecture Model (SGAM) framework and the Use Case Methodology. This paper shows and exemplifies the use of these tools to incrementally develop the automation architecture for future active distribution power systems, by leveraging on existing automation architectures...
In this paper, the data of information in intelligent substation are classified, information flow in communication network is analyzed, based on IEC61850 standards, and there are four categories: control and protection unit, the centralized fault recording unit, the monitoring and five-prevention unit and the measuring, in the application systems of substation. And then, the information integration...
Smart Grid (SG) is the current trend of the power grids in all the world, it will provide more robustness, efficiency, security, reliability, flexibility and quality of service than the current grids that have a lot of time without significant changes in their infrastructure. SG lets self-healing, modern bidirectional communications, more interaction of the users who can decide and know about their...
The purpose of this paper is to gather and document the most pertinent information about the “Smart Grid, ” explore its many components, and propose some suitable attributes while considering Distributed Generation (DG) interconnection as a major integral part. Effects of various Smart Grid components on Generation, Transmission, Substation and other sections of the power systems are identified and...
Power quality (PQ) has become a non-negligible issue for DNOs. More and more sites are being monitored permanently throughout their networks covering almost all voltage levels. Due to the continuously increasing number of measurement sites, certain issues become more and more evident. PQ analyzers usually run only in combination with proprietary software and data transfer methods. The interoperability...
WSNs (Wireless Sensor Networks) have been considered one of the very promising technologies for the implementation of smart grid. And security of WSNs becomes a central concern. The security solutions for generic wireless sensor networks cannot be directly used in smart grid WSNs. In this paper, the applications of sensor networks in electric power systems are discussed and analyzed first. Then, the...
This paper describes a major research initiative by British Columbia Institute of Technology for the construction of an Intelligent Micro Grid on its campus in Burnaby, BC, Canada.
Environmental concerns and power quality delivery needs have led regulators to sponsor new programs in energy efficiency, renewable energy capacity generation, and reliability improvements. Utilities are responding to those needs. This panel addresses emerging technology to enable smart grid deployment for improving energy efficiency.
