Derivation of the finite element energy functional for waveguides A practical approach to introducing variational finite elements to advanced microwave courses in electromagnetics is described. Using standard electromagnetic theory such as complex power flow and waveguide analysis an energy functional, based on the conservation of energy, is derived by applying the divergence theorem to the complex power flow equation.

Power flow transferring random occurred in power grid, so how to quickly identify overload line is a key problem to prevent cascading trips. This paper according to the bus self-impedance change rate rapid search the area which possible happened power flow transferring, and through the correction method for network equations checked the lines in this area whether overload or not, then selected the overload line caused by power flow transferring. Under the condition of known initial network parameters, this scheme according to the local network parameters modified to related calculation, improves the calculation speed, and has advantages for multipoint flow transferring recognition in complex power grid. Taking the New England 10-unit 39-bus system which also used this method as the example, in this case, this method is confirmed by the BPA simulation.

Raphson Method

SVC is incorporated in Newton Raphson method in which Power Flow Solution is a solution of the network under normal operation as well as network contingency, the model of SVC i.e. SVC Susceptance Model is discussed. Newton Raphson Power flow method has been developed for the steady behavior of large complex power systems, it allows the study of power flow under abnormal conditions as well as normal conditions. It is shown that how the system power losses are decreased after incorporating the SVC in this model. It is also shown that how the SVC is useful in network contingency. The results are generated for 5-Bus system.
