The microgrid with distributed PV and air source heat pump is studied, aim at the problem of controller saturation caused by the lag of the static switch and the mismatch between the operation mode and the control method, droop control is used in island mode and grid-connected mode, an improved pre-synchronization control algorithm is proposed to ensure the smooth transition of the microgrid transient...
Aiming at the problem of low identification accuracy for non-intrusive load identification technology at low sampling rate, a novel load identification algorithm based on maximum likelihood method is proposed for load monitoring and identification. Firstly, the event detection algorithm is proposed based on the load operation to judge load switching event. Then, the possibility of the load is determined...
Kernel-level Rootkit injects malicious code in the system kernel and realizes vicious function by modifying kernel code and data. The emergence of virtualization technology makes Rootkit hide itself and accesses system resources effectively. This paper proposes a kind of Rootkit based on VMM (VMRootkit) which can hide system process and system cannot find it. For realizing it, we firstly puts forward...
