Distributed voltage unbalance compensation for an islanded microgrid system in a sensitive load bus by Han, Ziying

“…The distributed secondary compensation is able to perform the similar compensation ability as centralized secondary structure; meanwhile, there are also improvement for special conditions including communication fault and plug-and-play. Simulations are carried out in Matlab Simulink environment, and cases involving communication failure, CL shift, and DG plug-out are tested and analyzed to verify the practicability of proposed design.…”

Intellectual property authentication by watermarking scan chain in design-for-testability flow by Cui, Aijiao, Chang, Chip Hong

“…As only the order of the scan cells is varied, the number of test vectors for the desired fault coverage is not affected. The advantage of this scheme is the ownership legitimacy can be publicly authenticated on-site by IP buyers after the chip has been packaged by loading a specific verification code into the scan chain. …”

Sizing of energy storage system for grid-connected inverters to enhance system stability by Chua, Shawn Zheng

“…ESS specifically activates during the inertial response (IR) and primary frequency response (PFR) during the occurrence of a fault. However, the optimal size and mix of ESS to be used to support the grid still requires much research and this is important as grids need to remain stable as loads may be shed or damaged if certain frequency boundaries are crossed. …”
