Power System State Estimator Market By Software Type (Utility & Power Control Centers), Application (Transmission & Distribution Networks) and Solution Methods (WLS, LAV, Kalman Filter, Bayesian, Newton Gaussian) - Global Trends & Forecasts To 2019
com)-- An innovative and highly valuable solution designed to effectively address a critical problem regarding electrical power grid control operations, the Smart State Estimator, has been developed by Bei Gou of Mansfield, Texas.
As in classical Kalman filtering, this state estimator alternates prediction and correction.
In March 2009, the new CAISO market, formerly known as MRTU, went into operation, and CAISO now has a day-ahead market, a real-time market, and a state estimator for the transmission network, as well as the ability to offer congestion revenue rights and settle and conduct market clearing functions.
The power system state estimator has been segmented by software as Utility and Power control center software; and by application as Transmission and Distribution segments.
NET based Graphical User Interface; Advanced Alarm Management System; Real-time and Historical Trending; Communications Front-end Processor; Historical Information System and Data Archiving; and Inter-Control Center Communications Protocol software products, as well as a full suite of Transmission Network Analysis applications including State Estimator, Topology Processor, Power Flow, Contingency Analysis and Operator training Simulator functions.
In the centre is the Vehicle State Estimator, which continually makes optimal estimates of the vehicle's position, velocity, heading, roll, pitch, and yaw, based on inputs from the GPS, IMU, vehicle sensors, and obstacle sensors.
The results of the state estimator are true physical solutions of the transmission system because of the mathematical characteristics of its power flow calculation method.
The report " Power System State Estimator Market by Software type (Utility & Power C ontrol C enters), Application (Transmission & Distribution Networks) and Solution Methods (WLS, LAV, Kalman Filter, Bayesian, Newton Gaussian) - Global Trends & Forecasts to 2019 " , published by MarketsandMarkets, defines and segments the global Power System State Estimator Market with an analysis and forecast of the market size.
Next, MISO intends to continue seeking new ways to extend the value gained from this technology by integrating it into our state estimator tool, incorporating use of the technology with additional transmission owners, and data sharing with the entire Eastern Interconnection.
Because of the mathematical characteristics of its power flow calculation method, EleQuant's state estimator provides results that are true physical solutions of the transmission system.
Development and implementation of the State Estimator as the organization's primary tool for monitoring reliability as of December 31, 2003.
