Application of State Estimation in Power System

Application of State Estimation in Power System: Application of State Estimation in Power System – In real-time environment the state estimator consists of different modules such as network topology processor, observability analysis, state estimation and bad data processing. The network topology processor is required for all power system analysis. A conventional network topology program uses …

Network Observability and Pseudo Measurements

Network Observability and Pseudo Measurements: A minimum amount of data is necessary for State Estimation (SE) to be effective. A more analytical way of determining whether a given data is enough for SE is called observability analysis. It forms an integral part of any real time state estimator.The ability to perform state estimation depends on …

Bad Data Detection in State Estimation of Power System

Bad Data Detection in State Estimation of Power System: The ability to identify Bad Data Detection in State Estimation measurements is extremely valuable to a load dispatch centre. One or more of the data may be affected by malfunction­ing of either the measuring instruments or the data transmission system or,both. Transducers may have been wired …

External System Equivalencing in Power System

External System Equivalencing in Power System: One of the widely practiced methods used for computational simplification is to divide the given system into three subsystems as shown in Fig. 14.4. One of these is referred to as the ‘internal’ subsystem and consists of those buses in which we are really interested. The second subsystem consists …
