Switching Frequency Limitation with Finite Control Set Model Predictive Control via Slack Variables
Luca M. Hartmann, Orcun Karaca, Tinus Dorfling +1
Past work proposed an extension to finite control set model predictive control to track both a current reference and a switching frequency reference, simultaneously. Such an object…
Actuator Placement for Structural Controllability beyond Strong Connectivity and towards Robustness
Baiwei Guo, Orcun Karaca, Sepide Azhdari +2
Actuator placement is a fundamental problem in control design for large-scale networks. In this paper, we study the problem of finding a set of actuator positions by minimizing a g…
Performance guarantees of forward and reverse greedy algorithms for minimizing nonsupermodular nonsubmodular functions on a matroid
Orcun Karaca, Daniel Tihanyi, Maryam Kamgarpour
This letter studies the problem of minimizing increasing set functions, or equivalently, maximizing decreasing set functions, over the base of a matroid. This setting has received…
A market-based approach for enabling inter-area reserve exchange
Orcun Karaca, Stefanos Delikaraoglou, Maryam Kamgarpour
Considering the sequential clearing of energy and reserves in Europe, enabling inter-area reserve exchange requires optimally allocating inter-area transmission capacities between…
A convex relaxation approach for the optimized pulse pattern problem
Lukas Wachter, Orcun Karaca, Georgios Darivianakis +1
Optimized Pulse Patterns (OPPs) are gaining increasing popularity in the power electronics community over the well-studied pulse width modulation due to their inherent ability to p…
Enabling inter-area reserve exchange through stable benefit allocation mechanisms
Orcun Karaca, Stefanos Delikaraoglou, Gabriela Hug +1
The establishment of a single European day-ahead market has accomplished the integration of the regional day-ahead markets. However, the reserves provision and activation remain an…
Actuator Placement under Structural Controllability using Forward and Reverse Greedy Algorithms
Baiwei Guo, Orcun Karaca, Tyler Summers +1
Actuator placement is an active field of research which has received significant attention for its applications in complex dynamical networks. In this paper, we study the problem o…
Actuator Placement for Optimizing Network Performance under Controllability Constraints
Baiwei Guo, Orcun Karaca, Tyler Summers +1
With the rising importance of large-scale network control, the problem of actuator placement has received increasing attention. Our goal in this paper is to find a set of actuators…
