Regulating radio-frequency fields in Italy
IEEE Technology and Society Magazine, 2002 Throughout the world, there has been a move to "harmonize" exposure limits to radio-frequency (RF) energy from sources such as mobile phones, communications transmitters, radar, industrial equipment, and the like. "Harmonization", in practice, means the adoption of a consistent set of exposure limits in different nations around the world.

Improvement of Frequency Regulation in VSG-Based AC Microgrid Via Adaptive Virtual Inertia
IEEE transactions on power electronics, 2020 A virtual synchronous generator (VSG) control based on adaptive virtual inertia is proposed to improve dynamic frequency regulation of microgrid. When the system frequency deviates from the nominal steady-state value, the adaptive inertia control can ...

Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging [PDF]
, 2015 In this work we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor communication

Model Predictive Control for EV Aggregators Participating in System Frequency Regulation Market
IEEE Access, 2021 The penetration rate of renewable energy source generation in power systems continues to increase in recent years. However, due to the intermittent nature of renewable energy source (RES) generation, more frequency regulation resources with faster ...

Distributed LQR design for identical dynamically coupled systems: Application to load frequency control of multi-area power grid [PDF]
, 2019 The paper proposes a distributed LQR method for the solution to regulator problems of networks composed of dynamically dependent agents. It is assumed that these dynamical couplings among agents can be expressed in a state-space form of a certain ...
