Averaging favors MPC: How typical evaluation setups overstate MPC performance for residential battery scheduling
Janik Pinter, Maximilian Beichter, Ralf Mikut +2
Residential prosumers with PV-battery systems increasingly manage their electricity exchange with the power grid to minimize costs. This study investigates the performance of Model…
Numerical estimation of the lock-in domain of a DC/AC inverter
Anton Ponomarev, Lutz Gröll, Veit Hagenmeyer
We estimate the lock-in domain of the origin of a current control system which is used in common DC/AC inverter designs. The system is a cascade connection of a 4-dimensional linea…
Distributed AC Optimal Power Flow: A Scalable Solution for Large-Scale Problems
Xinliang Dai, Yuning Jiang, Yi Guo +3
This paper introduces a novel distributed optimization framework for large-scale AC Optimal Power Flow (OPF) problems, offering both theoretical convergence guarantees and rapid co…
Probabilistic Day-Ahead Battery Scheduling based on Mixed Random Variables for Enhanced Grid Operation
Janik Pinter, Frederik Zahn, Maximilian Beichter +2
The increasing penetration of renewable energy sources introduces significant challenges to power grid stability, primarily due to their inherent variability. A new opportunity for…
Real-Time Coordination of Integrated Transmission and Distribution Systems: Flexibility Modeling and Distributed NMPC Scheduling
Xinliang Dai, Yi Guo, Yuning Jiang +3
This paper proposes a real-time distributed operational architecture to efficiently coordinate intergrated transmission and distribution systems (ITD). At the distribution system l…
Hypergraph-Based Fast Distributed AC Power Flow Optimization
Xinliang Dai, Yingzhao Lian, Yuning Jiang +2
This paper presents a novel distributed approach for solving AC power flow (PF) problems. The optimization problem is reformulated into a distributed form using a communication str…
Distributed Optimal Power Flow for VSC-MTDC Meshed AC/DC Grids Using ALADIN
Junyi Zhai, Xinliang Dai, Yuning Jiang +4
The increasing application of voltage source converter (VSC) high voltage direct current (VSC-HVDC) technology in power grids has raised the importance of incorporating DC grids an…
Distributed Power Flow and Distributed Optimization -- Formulation, Solution, and Open Source Implementation
Tillmann Mühlpfordt, Xinliang Dai, Alexander Engelmann +1
Solving the power flow problem in a distributed fashion empowers different grid operators to compute the overall grid state without having to share grid models-this is a practical…
Partially Distributed Outer Approximation
Alexander Murray, Timm Faulwasser, Veit Hagenmeyer +2
This paper presents a novel partially distributed outer approximation algorithm, named PaDOA, for solving a class of structured mixed integer convex programming (MICP) problems to…
The Price of Uncertainty: Chance-constrained OPF vs. In-hindsight OPF
Tillmann Mühlpfordt, Veit Hagenmeyer, Timm Faulwasser
The operation of power systems has become more challenging due to feed-in of volatile renewable energy sources. Chance-constrained optimal power flow (ccOPF) is one possibility to…
A Generalized Framework for Chance-constrained Optimal Power Flow
Tillmann Mühlpfordt, Timm Faulwasser, Veit Hagenmeyer
Deregulated energy markets, demand forecasting, and the continuously increasing share of renewable energy sources call---among others---for a structured consideration of uncertaint…
