Systematic principal component analysis (PCA) methods are presented in this paper for reliable islanding detection for power systems with significant penetration of distributed generations (DGs), where synchrophasors, recorded by phasor measurement units, are used for system monitoring. Existing islanding detection methods, such as rate-of-change-of-frequency and vector shift are fast for processing...
In this paper we proposed a mathematical model for mission planning problem of collaborate jamming resource. In the practical problem of collaborate jam of warships and aircrafts computational time is limited stiffly, and the allocation scheme of multiple targets and multiple jamming devices should be dynamical in practical case. Moreover, the problem is multi-objective and multi-constraint conditions...
