Design of an Open Platform for Real-Time Power Grid Monitoring

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019

This paper presents the design and implementation of the UK's first open platform for acquiring, archiving, and visualizing high-resolution real-time measurement data from Phasor Measurement Units (PMUs). The platform, termed "Smart Grid Monitoring and Visualization Platform (SGMVP)", is also capable of accessing and sharing the operational data of the Great Britain (GB) transmission network (e.g. demand level, output of different generation units, power flow in interconnectors, etc.). SGMVP provides an ideal solution for open and convenient access to valuable grid data, which enables a wide range of potential applications (e.g. power system model validation, provision of training data for data-driven approaches in power systems, etc.). In this paper, the architecture of the SGMVP platform and the design and implementation of the key functional blocks will be presented in detail. Discussion of the potential use cases of the platform for various purposes is presented. Future plans for further developing the platform to incorporate more PMUs from different locations in the GB power network are discussed. Index Terms-real-time monitoring, PMU, wide-area monitoring, protection and control, renewable generation.

A Grid Computing Service for Power System Monitoring

Extensively interconnected power grid has been a long cherished dream of the power system engineers. Recently, the incredible publicity of smart grid has brought about a revolution in the way the power system’s operation and control functions are planned. However, attempts to interconnect power system grids have consistently resulted in failures, like cascaded failures, often leading to black-outs. Taking into account the real-time requirements to deal with power system diagnostic procedures, it is absolutely essential to have an effective and reliable monitoring of the entire system. In this paper, we have implemented the monitoring of Odisha power grid to fulfill the requirement of distinguished power system protection. This paper advocates the use of grid computing in power system monitoring. Even though, the Supervisory Control and Data Acquisition/Energy Management System (SCADA/EMS) system is presently being used for monitoring power systems; yet it has its boundaries. This paper proposes to use Grid Computing as a support to the existing SCADA/EMS based power system monitoring and control and demonstrates its applicability by means of a grid based synchronized power system monitoring system. Therefore mentioned system has been deployed in desktop computers with GridGain 2.0 as middleware.

A Grid Information Resource for Nationwide Real-Time Power Monitoring

IEEE Transactions on Industry Applications, 2004

A significant barrier to improving the power quality at industrial facilities is the lack of contemporaneous and historical power quality and reliability data. A new Web-enabled near-real-time power quality and reliability monitoring system, termed I-Grid, has been developed to provide such information on a nationwide basis. The ultralow-cost sensors record power events and send event data via the Internet to the system database servers using an internal modem. Data display, e-mail event notification, site administration, and summary reporting of the data are achieved via a Web browser. In cooperation with the U.S. Department of Energy, the Electric Power Research Institute, and leading utilities and manufacturers, the deployment of these sensors has begun, with a target deployment of 50 000 monitors across the U.S. and Canada over the next 2-4 years. This paper discusses the implementation of this grid information resource, and discusses data captured by the network since early monitors were deployed in 2001.

Monitoring system for the local distributed generation infrastructures of the smart grid

IET Conference Publications, 2013

Distributed generation infrastructures based on renewable energies represent a key piece of the Smart Grid puzzle. However, such infrastructures increase dramatically the variability and randomness of energy generation, thus increasing the complexity of the grid management. Therefore, they need to be carefully monitored in order to properly integrate them into the electrical grid. This paper presents the novel monitoring system for distributed generation infrastructures integrated into the M2M-based platform for energy efficiency in energy-positive neighbourhoods which is being developed under the European project ENERsip. The paper describes the overall architecture of such monitoring system, as well as the developed pieces of hardware and software. In addition, the validation of the system is also outlined.

Towards more flexible and robust data delivery for monitoring and control of the electric power grid

School Elect. Eng. Comput …, 2007

With the increase in the monitoring of status data at very high rates in high voltage substations and the ability to time synchronize these data with GPS signals, there is a growing need for transmitting this data for monitoring, operation, protection and control needs. The sets of data that need to be transferred and the speed at which they need to be transferred depend on the applicationfor example, slow for post-event analysis, near real-time for monitoring and as close to real-time as possible for control or protection. In this paper, we overview the requirements for the next-generation power grid's communication infrastructure in the areas of flexibility and quality of service, with extensive citations of power industry practitioners and researchers, and analyze implementation options. We also overview technologies in the computer science field of distributed computing that can be brought to bear to help meet these requirements, yet to date have not been discussed in the context of grid modernization. Additionally, we argue against the industry trend of using either TCP/IP or web services for real-time data exchange for fast controls. We then describe GridStat, a novel middleware framework we have developed that is suitable for the power grid and its application programs. Test results demonstrate that such a flexible framework can also guarantee latency that is suitable for fast wide-area protection and control.

Real-Time Low Voltage Network Monitoring—ICT Architecture and Field Test Experience

IEEE Transactions on Smart Grid, 2015

Traditionally, distribution network monitoring has been focused on primary substations (i.e., high voltage/medium voltage level), whereas low voltage (LV) network has not been monitored at all. With rapid growth and penetration of distributed energy resources in LV grids, there is growing interest in extending the real-time monitoring to LV level. The framework program FP7 European Project INTEGRIS proposes an integrated real-time LV network monitoring solution and implements it in a cost-efficient way. This solution integrates smart metering data with secondary substation measurements to get a more accurate and real-time view about LV grid, uses "decentralized" distribution management architecture to optimize data flow, and uses International Electrotechnical Commission 61850 Standardbased interfaces to improve interoperability. This paper focuses on information and communications technology perspective, explains the implementation details of this monitoring solution, and presents its functionality/performance testing results from two distribution system operator field trials and from real-time digital simulator laboratory.

Online Monitoring of Distributed Generation Systems

International journal of Engineering Works, 2021

As renewable energy is intermittent in nature, its integration in to the power grid is challenging task. Hence remote monitoring and data acquisition of various performance parameters from the renewable energy systems has become of paramount importance. Round the clock monitoring of the system ensures the stable and reliable operation of the system, by proper management, in this way an individual at a remote location can know whether the system is producing sufficient energy or not which is essential for its stable operation. This feature can be ensured by the use of real-time performance monitoring. If it is observed the sources is not working properly then an immediate remedy can be done to it before it sets in a chain of events and make things worse. The proposed monitoring system formulates unified data acquisition standard for distributed RES and real-time monitoring of RES such as solar PV. The system is an IoT server based using an Arduino to send the real-time power production to the cloud for remote access by the operator or the owner.
