This paper presents an improved entropy method to assess the post-fault power system. The proposed method defines four indicators to assess the seriousness of the post-fault power system according to the specified severity function from the aspects of static stability and transient stability, and to weight the severity indicators through an improved entropy method. The risk assessment function for system failure is then established by combining the severity function with line fault probability model from statistical analysis of historical in power system. This proposed method has been tested with IEEE - 9 nodes system. Simulation results show that the proposed improved entropy method is able to make full use of various information, effectively avoids the problem of over weighting of any indicators, and improves the reliability and accuracy of the failure risk assessment of the power system.

We present a new concept of the thermoelectric structure that generates microwave and terahertz signals when illuminated by femtosecond optical pulses. The structure consists of a series array of capacitively coupled thermocouples. The array acts as a hybrid type microwave transmission line with anomalous dispersion and phase velocity higher than the velocity of light. This allows for adding up the responces from all the thermocouples in phase. The array is easily integrable with microstrip transmission lines. Dispersion curves obtained from both the lumped network scheme and numerical simulations are presented. The connection of the thermocouples is a composite right/left-handed transmission line, which can receive terahertz radiation from the transmission line ports. The radiation of the photon to the surface of the thermocouple structure causes a voltage difference with the bandwidth of terahertz. We examined a lossy composite right/left-handed transmission line to extract the circuit elements. The calculated properties of the design are extracted by employing commercial software package CST STUDIO SUITE.
