Hybrid Microgrid Control Optimization for Reactive Power Compen sation (HyMiCO-RPC)

The Hybrid Microgrid Control Optimization for Reactive Power Compensation (HyMiCO-RPC) 
project focused on enhancing reactive power management in hybrid AC/DC microgrids through 
the application of intelligent fuzzy-based control algorithms. The objective was to improve voltage 
stability and power quality by optimizing reactive power dispatch across multiple distributed 
energy resources (DERs), particularly inverter-based systems. The experimental activities were 
carried out using the real-time simulation and hardware-in-the-loop (HIL) infrastructure at the 
designated ERIGrid partner laboratory, following the same methodology applied in the DRIMPC
Stability project. 
During the access period, a hybrid microgrid system model was implemented, featuring a 
combination of photovoltaic (PV), battery energy storage systems (BESS), and grid-connected 
inverters. Fuzzy logic controllers were designed and tuned to coordinate reactive power support 
from inverters under varying load and grid conditions. Real-time validation included tests 
comparing the fuzzy-based control approach with conventional rule-based control methods in 
terms of reactive power optimization, voltage profile improvements, and system robustness. The 
results demonstrated significant enhancements in voltage regulation and power factor correction 
while reducing unnecessary inverter stress and energy losses. 
This project contributes to the advancement of autonomous grid-support functionalities in hybrid 
microgrids and supports the integration of flexible DERs into distribution networks. The outcomes 
serve as a foundation for future research on scalable and adaptive reactive power control 
strategies in decentralized energy systems.
