Rate-induced transitions and advanced takeoff in power systems

Area of Science:

• Engineering
• Complex Systems Dynamics
• Power Systems Analysis

Background:

• Complex systems in nature and engineering often fail due to abrupt shifts between stable states.
• Such state transitions are a critical failure mechanism in dynamic power systems.
• Understanding these transitions is key to preventing catastrophic failures.

Purpose of the Study:

• To investigate the transition from a stable to an unstable manifold in a theoretical power system model.
• To analyze the influence of rate-dependent mechanical power input on system stability.
• To identify critical transition rates and their dependence on initial conditions.

Main Methods:

• Numerical investigation of a theoretical power system model.
• Analysis of rate-dependent mechanical power input.
• Determination of the relationship between transition rate and initial system conditions.

Main Results:

• Early transitions to unstable states are dependent on the rate of mechanical input variation.
• A critical rate for these transitions was identified.
• The critical rate shows a dependency on the initial conditions of the power system.

Conclusions:

• The rate of mechanical input significantly impacts the timing of state transitions in power systems.
• Knowledge of the critical rate and its dependency on initial conditions is crucial for system stability.
• This understanding can inform the development of effective artificial intelligence (AI)-based control strategies for power systems.
