Advanced Safety Filter for Smooth Transient Operation of a Battery Energy Storage System
Michael Schneeberger, Florian Dörfler, Silvia Mastellone
In this paper, we implement an advanced safety filter to smoothly limit the current of an inverter-based Battery Energy Storage System. The task involves finding suitable Control B…
Advanced safety filter based on SOS Control Barrier and Lyapunov Functions
Michael Schneeberger, Silvia Mastellone, Florian Dörfler
This paper presents a novel safety filter framework that ensures both safety and the preservation of the legacy control action within a nominal region. This modular design allows t…
SOS Construction of Compatible Control Lyapunov and Barrier Functions
Michael Schneeberger, Florian Dörfler, Silvia Mastellone
We propose a novel approach to certify closed-loop stability and safety of a constrained polynomial system based on the combination of Control Lyapunov Functions (CLFs) and Control…
An exact relaxation of AC-OPF problem for battery-integrated power grids
H. Sekhavatmaneshand, S. Mastellone
Renewable energy resources and power electronics-interfaced loads introduce fast dynamics in distribution networks. These dynamics cannot be regulated by slow conventional solution…
Optimal droop control placement in distribution network via an exact OPF relaxation method
H. Sekhavatmanesh, G. Ferrari-Trecate, S. Mastellone
In the last decade, the integration of Renewable Energy Sources (RES) in distribution networks has been constantly increasing due to their many technical, economical, and environme…
Optimal Adaptive Droop Design via a Modified Relaxation of the OPF
H. Sekhavatmanesh, G. Ferrari-Trecate, S. Mastellone
The ever increasing penetration of Renewable Energy Resources (RESs) in power distribution networks has brought, among others, the challenge of maintaining the grid voltages within…
