Juan M. Rey
Associate Professor, UIS
David is working on designing control strategies for grid-connected three-phase inverters with LVRT capabilities to increase system stability and reliability. He is currently studying current reference generators that simultaneously consider operative control objectives such as current limitation, optimal voltage support, mitigation of DC oscillations, among others.

David Rincón-Adarme, PhD Student.
Juan is working on modeling the occupancy in institutional buildings for optimal energy management. He is studying how to use low-cost sensors, variable classification techniques and novel algorithms to predict occupancy behaviour in order to minimize building energy consumption (e.g., the use of HVAC) while guaranteeing the users' comfort.
