Robustness to Wind Power Output Drop
In a test scenario, the wind power output abruptly dropped by 70% at hour 18:00, simulating a severe disturbance. The MGNDO algorithm demonstrated strong resilience.
Challenge: Maintaining stable operation and load coverage during a sudden 70% drop in wind power output.
Solution: The system automatically shifted its energy balance by increasing battery discharging and purchasing power from the main grid.
Result: Full load coverage was maintained without renewable curtailment. Operating costs rose only 1.9% despite the severe disturbance, showcasing the model's real-time adaptability.
