Optimal Grid-Forming Control of Battery Energy Storage Systems Providing Multiple Services: Modelling and Experimental Validation
Francesco Gerini, Yihui Zuo, Rahul Gupta +3
This paper proposes and experimentally validates a joint control and scheduling framework for a grid-forming converter-interfaced BESS providing multiple services to the electrical…
Local Effects of Grid-Forming Converters Providing Frequency Regulation to Bulk Power Grids
Antonio Zecchino, Francesco Gerini, Yihui Zuo +3
The progressive displacing of conventional generation in favour of renewable energy sources requires restoring an adequate capacity of regulating power to ensure reliable operation…
Effect of Voltage Source Converters with Electrochemical Storage Systems on Dynamics of Reduced-inertia Bulk Power Grids
Yihui Zuo, Mario Paolone, Fabrizio. Sossan
A major concern associated to the massive connection of distributed energy resources is the increasing share of power electronic interfaces resulting in the global inertia reductio…
PMU-Based ROCOF Measurements: Uncertainty Limits and Metrological Significance in Power System Applications
Guglielmo Frigo, Asja Derviskadic, Yihui Zuo +1
In modern power systems, the Rate-of-Change-of-Frequency (ROCOF) may be largely employed in Wide Area Monitoring, Protection and Control (WAMPAC) applications. However, a standard…
Dispatch and Primary Frequency Control with Electrochemical Storage: a System-wise Verification
Yihui Zuo, Fabrizio Sossan, Mokhtar Bozorg +1
Uncertainty levels in forecasting of renewable generation and demand are known to affect the amount of reserve required to operate the power grid with a given level of reliability.…
Under Frequency Load Shedding based on PMU Estimates of Frequency and ROCOF
Asja Derviškadić, Yihui Zuo, Guglielmo Frigo +1
The paper describes a distributed under-frequency load shedding and load restoration scheme, that exploits frequency and Rate-of-Change-of-Frequency (ROCOF) measurements produced b…
