Wide-area, real-time monitoring and visualization system

Abstract

A real-time performance monitoring system for monitoring an electric power grid. The electric power grid has a plurality of grid portions, each grid portion corresponding to one of a plurality of control areas. The real-time performance monitoring system includes a monitor computer for monitoring at least one of reliability metrics, generation metrics, transmission metrics, suppliers metrics, grid infrastructure security metrics, and markets metrics for the electric power grid. The data for metrics being monitored by the monitor computer are stored in a data base, and a visualization of the metrics is displayed on at least one display computer having a monitor. The at least one display computer in one said control area enables an operator to monitor the grid portion corresponding to a different said control area.

AI Technical Summary

Benefits of technology

[0009]In one exemplary application of the present invention, a power grid monitoring and management system is provided. The power grid monitoring and management system includes a technology platform for real-time performance monitoring application for the electric power grid. The power grid monitoring and management system in one exemplary embodiment may also be referred to as a Grid Real-Time Performance Monitoring and Prediction Platform (Grip-3PTM). The Grid-3P platform is designed to enable monitoring of a range of electric grid parameters, including metrics for reliability, markets, generation, transmission, operation, and security. The visualization features enable display of information geographically and graphically; in real time; and enables operators to define display levels—local or wide area, control area, interconnection or other user defined manner. This technology is being used to develop and implement real-time performance monitoring applications at Reliability Coordinator and Independent System Operator (ISO) locations, including the following applications: Area Control Error (ACE)-Frequency Real-Time Monitoring System; Control Area and Supplier's Performance for Automatic Generation Control and Frequency Response Services System; VAR-Voltage Management and Monitoring System; and Monitoring Applications based on Synchronized Phasor Measurements.

Problems solved by technology

While all these different entities at various different levels are involved in generation, transmission and distribution of electricity as well as monitoring and control in a power grid, there is no single integrated system that can be used to monitor and manage the electric power grid in real-time across all of the different elements of the power system.

Analogous issues may be apparent in other industries.
