Optimal Distributed Frequency and Voltage Control for Zonal Electricity Markets

Lukas Kölsch, Lena Zellmann, Rishabh Vyas +2

Zonal pricing is a well-suited mechanism to incentivize grid-supporting behavior of profit-maximizing producers and consumers operating on a large-scale power system. In zonal elec…

Formal self duality

Lukas Kölsch, Robert Schüler

We study the notion of formal self duality in finite abelian groups. Formal duality in finite abelian groups has been proposed by Cohn, Kumar, Reiher and Schürmann. In this paper w…

On CCZ-equivalence of the inverse function

Lukas Kölsch

The inverse function on is one of the most studied functions in cryptography due to its widespread use as an S-box in block ciphers like AES.…

Optimal Control of Port-Hamiltonian Systems: A Time-Continuous Learning Approach

Lukas Kölsch, Pol Jané Soneira, Felix Strehle +1

Feedback controllers for port-Hamiltonian systems reveal an intrinsic inverse optimality property since each passivating state feedback controller is optimal with respect to some s…

On the inverses of Kasami and Bracken-Leander exponents

Lukas Kölsch

We explicitly determine the binary representation of the inverse of all Kasami exponents modulo for all possible values of and . This includes as…

Distributed Frequency and Voltage Control for AC Microgrids based on Primal-Dual Gradient Dynamics

Lukas Kölsch, Katharina Wieninger, Stefan Krebs +1

With the gradual transformation of power generation towards renewables, distributed energy resources are becoming more and more relevant for grid stabilization. In order to involve…
