Vulnerability Analysis Evaluating Bilevel Optimal Power Flow Approaches for Multiple Load Cases
Eric Tönges, Martin Braun, Philipp Härtel
This work presents two methodologies to enhance vulnerability assessment in power systems using bilevel attacker-defender network interdiction models. First, we introduce a systema…
A Computationally Efficient Method for Solving Mixed-Integer AC Optimal Power Flow Problems
Johannes Heid, Nils Bornhorst, Eric Tönges +3
Stepwise controllable devices, such as switched capacitors or stepwise controllable loads and generators, transform the nonconvex AC optimal power flow (AC-OPF) problem into a nonc…
Bilevel Optimization for Improved Flexibility Aggregation Models of Electric Vehicle Fleets
Philipp Härtel, Michael von Bonin
Electric vehicle (EV) fleets are expected to become an increasingly important source of flexibility for power system operations. However, accurately capturing the flexibility poten…
Vulnerability-Based Optimal Grid Defense Strategies for Enhancing Cyber-Physical Energy System Resilience
Eric Tönges, Martin Braun, Philipp Härtel
An approach is proposed to identify optimal asset protection strategies based on vulnerability assessment outcomes. Traditional bilevel attacker-defender models emphasize worst-cas…
