Description
A DC microgrid mixing solar panels with storage must hold its bus voltage steady while clouds and loads keep shifting. Syphax Ihammouchen and co-authors control a hybrid store, batteries for the steady work and supercapacitors for sudden bursts. Their scheme pairs a standard voltage controller with a nonlinear high-gain observer that watches for disturbances and cancels them.
Ordinary high-gain observers suffer a trade-off: raise the gain and noise creeps in; lower it and response slows. Their observer varies its gain, running hot during transients to catch disturbances fast, then cooling in steady state to shut out noise. Simulation and real-time bench tests showed up to forty-five percent less voltage overshoot and thirty-five percent faster settling than three rival observer schemes. The system also split power between battery and supercapacitor sensibly across conditions and shrugged off parameter changes.
