The concrete work and main contribution are as follows:(1) The index indicating transfer capability homogeneousness is defined, and the new terms like homogeneous grid, grid according with economic flow are put forward. These new concepts describe the degree in which transfer capability is utilized, and they provide the standard for ideal grid whose transfer capability and power generation dispatching economy are in phase. So, new idea is introduced in transfer capability analysis.(2) The multi-objective function with generation cost and transfer capability homogeneousness weighted is constructed. The relationship between system existing generation dispatching and transfer capability is revealed through comparative analysis between security economic dispatch and security homogeneous dispatch, and the variation rule analysis between generation cost and transfer capability homogeneousness with the change of weighting coefficient.(3) Example analyses demonstrate that the difference between specific power system with ideal instance can be identified effectively using the above concepts and method.

In this work, the performance of six-needle steel electrodes and four-needle graphite electrodes in detecting bio-impedance was compared. Also, coefficients of variability were applied to assess the stability of the system. Experiment showed that the coefficient of variation of the system was less than 6% if the frequency was above 1 kHz. Intra class correlation procedures were applied to assess the reliability of the system due to temperature variability. Values of Ri, Re, C in the system model were reliable with intra class correlations of more than 65%.
