A Grid Computing Based Power System Monitoring Tool Using Gridgain (original) (raw)

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.

Applications of Grid Computing in Power Systems

Grid computing is an infrastructure that involves the integrated and collaborative use of computers, networks, databases and scientific instruments owned and managed by multiple organizations . Currently, Grid computing is effectively used in scientific research, oil and gas fields, banking and education. It has provided significant contribution in these areas. In this paper, we introduce the fundamentals and applications of Grid computing in order to provide more open access and more efficient & effective computing services to meet the increasing needs of the power industry, especially in the context of a competitive electricity market. Power system applications developed on the Grid computing can provide real time information for the whole system. Grid computing can provide services in power generation, transmission distribution and in its marketing . It can also provide efficient and effective services in the power system monitoring, scheduling, fault detection, transmission congestion management, planning, and electricity market analysis such as forecasting. In this paper, we will give detailed analysis of Grid computing in the context of power system applications. We will also investigate the existing Grid computing and similar computing applications in practice, and propose a general framework of Grid computing in power systems application approach.

RSA-grid: a grid computing based framework for power system reliability and security analysis

2006

Grid computing is an emerging technology for providing the high performance computing capability and collaboration mechanism for solving the collaborated and complex problems while using the existing resources. In this paper, a grid computing based framework is proposed for the probabilistic based power system reliability and security analysis. The suggested name of this computing grid is reliability and security grid (RSA-grid). Then the architecture of this grid is presented. A prototype system has been built for further development of grid-based services for power systems reliability and security assessment based on probabilistic techniques, which require high performance computing and large amount of memory. Preliminary results based on prototype of this grid show that RSA-grid can provide the comprehensive assessment results for real power systems efficiently and economically

Intelligent Integrated Energy Systems, 2018

The situational grid awareness is becoming increasingly important for power system operations due to smaller operational margins, wide range of uncertainties entailed by renewables and highly critical infrastructure failures due to potential cyber-attacks. In this chapter, we look at some of the state-of-the-art technologies to monitor events in a power system under normal operating condition, followed by detection algorithms for regular business risk events, such as faults and equipment failures, and finally, we look into methods for quantifying vulnerability of under the rare and men-orchestrated cyber-attacks. First, we outline an architecture of a central piece of today’s grid awareness system, Wide Area Monitoring, Protection and Control technology. Next, we review an event detection method used to identify and record faults and failures in the grid. Finally, we present a method for vulnerability assessment of grids under cyber-attacks.

International Journal of Electrical and Computer Engineering (IJECE), 2019

The use of grid power systems based on the combinations of various electrical networks, information technology, and communication layers called as Smart Grid systems. The technique of smart grid suppressed the problems faced by conventional grid systems such as inefficient energy management, improper control actions, grid faults, human errors, etc. The recent research on smart grid provides the approach for the real-time control and monitoring of grid power systems based on bidirectional communications. However, the smart grid is yet to improve regarding efficiency, energy management, reliability, and cost-effectiveness by considering its real-time implementation. In this paper, we present the real-time design of efficient monitoring and control of grid power system using the remote cloud server. We utilized the remote cloud server to fetch, monitor and control the real-time power system data to improve the universal control and response time. The proper hardware panel designed and fabricated to establish the connection with the grid as well as remote cloud users. The authenticated cloud users are provisioned to access and control the grid power system from anywhere securely. For the user authentication, we proposed the novel approach to secure the complete smart grid system. Finally, we demonstrated the effectiveness of real-time monitoring and control of the grid power method with the use of structure of practical framework.

Dynamic Monitoring Of Information in Large Scale Power Grids

this document proposes the software model for detection and analysis of cascading faults in the operation of large scale power grids. Using data mining technologies, probable patterns can be detected for faults and proper mitigation measures can be taken. Firstly, the fault is detected by checking the stability of system. Then event sequences are calculated to best approximate the fault node. Then by analyzing the severity of vulnerability and region in which vulnerability would occur, proper ICT Technologies can make operators aware about the faults. Hence, speeding up the existing mechanisms. This model aims to solve problem of detection more efficiently than existing systems.

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.
