Frequency Shaping for Improving a Trade‐Off Between Control and Privacy Performance: Beyond Differential Privacy

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...

Insight into microgrid protection

IEEE PES Innovative Smart Grid Technologies, Europe, 2014
Microgrids consist of a combination of generation resources and load, forming an electrically sustainable entity. Although the feeder configuration, including location of circuit breakers or switches, and selection of protective devices can change from one microgrid to another, some characteristics like size of microgrid and behavior of sources feeding
