Current distribution line protection in smart grid can’t be solved well in low sensitivity and unsatisfied rapidity by protection principle nowadays. The wavelet analysis has a strong feature-extracting function, which can extract the fault signatures of the fault phase. In this paper, the EMTP is used to make simulations and wavelet transformations of power line-end short-circuit failure, fault-phase...
Particle Swarm optimization algorithm is presented for the layout of IC design. Particle swarm optimization based on swarm intelligence is a new evolutionary computational tool and is successfully applied in function optimization, neural network design, classification, pattern recognition, signal processing and robot technology and so on. A modified algorithm is presented and applied to the layout...
This paper mainly illustrates that electricity purchasers face the decision of electricity purchase and the issues of risk managements in the four trading markets under the framework of the electricity markets. The restrictions and non-restriction purchase/sale of two purchasing electricity models are set up by means of Variance measuring risk under the framework of the electricity market. Meanwhile,...
