Load Compensation in Power System: Load compensation is the management of reactive power to improve power quality i.e. V profile and pf. Here the reactive power flow is controlled by installing shunt compensating devices (capacitors/reactors)…
Limitations for Loading Capability of Transmission System: There are three kinds of limitations for loading capability of transmission system: Thermal Dielectric Stability Thermal capability of an overhead line is a function of the ambient temperature,…
What is Compensation in Power System: Introduction to Compensation in Power System - For reduction of cost and improved reliability, most of the world's electric power systems continue to be interconnected. Interconnections take advantage of…
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…
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…
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…
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…
Tracking State Estimation of Power Systems: Tracking State Estimation of Power Systems is important for real time monitoring of the system. As is well known, the voltages of all real system vary randomly with time…
Static State Estimation in Power Systems: Static State Estimation in Power Systems - As noted earlier, for a system with N buses, the state vector x may be defined as the 2N — 1 vector…
Least Square Estimation Method: As we are going to seen that, the problem of power system state estimation is a special case of the more general problem of estimation of a random vector x from…
