Model Predictive Control based Energy Management System for Home Energy Resiliency

no code implementations8 Apr 2024 Ninad Gaikwad, Shishir Lamichhane, Anamika Dubey

However, to provide habitable conditions this energy system has to provide not only for the non-air-conditioning (non-AC) load demand but also for the turning on of the AC system which has a considerably higher startup power requirement as compared to its rated power.

Small-Signal Dynamics of Lossy Inverter-Based Microgrids for Generalized Droop Controls

no code implementations4 Apr 2024 Abdullah Al Maruf, Anamika Dubey, Sandip Roy

Simulated transient responses of a modified IEEE 9-bus system are presented to validate the theoretical findings which show the effectiveness of generalized droop controls in independently shaping the settling times of the angle and voltage responses of the lossy microgrid system.

Resilience-driven Planning of Electric Power Systems Against Extreme Weather Events
