Model Predictive Control in Microgrids Considering Demand Management, Hybrid Energy Storage and User Satisfaction
This lecture presents a Model Predictive Control (MPC) strategy to act as a Energy Management System for Microgrids Considering Demand Management, Hybrid Energy Storage and User Satisfaction. The proposed MPC is responsible for supervising the operation of the microgrid, where it accounts for both economic performance and demand management (DM) actions taking into account user comfort, and adopting a quality of experience (QoE) metric. A smart house is used in the study to analyse the performance of the proposed controller. The energy storage in this smart house is done using batteries and renewable hydrogen, which results in a reduction of pollutant emissions. The Model Predictive Control formulation uses a mixed-integer quadratic programming (MIQP) optimization, which avoids the use of nonlinear optimization tools. Validated by simulation, the system achieves the required standards: runs the smart house for a year with a 21% electricity bill reduction and 77% reduction in user discomfort.

José Antenor Pomilio (M’92–SM’02) was born in Jundiaí, Brazil, in 1960. He received his B.S., M.S.,
and Ph.D. in electrical engineering from the University of Campinas, Campinas, Brazil, in 1983, 1986,
and 1991, respectively. From 1988 to 1991, he was the Head of the Power Electronics Group, Brazilian
Synchrotron Light Laboratory. He was a visiting professor at the University of Padova in 1993 and 2015
and at the Third University of Rome in 2003 in Italy. He is a Professor at the School of Electrical and
Computer Engineering, University of Campinas, where he has been teaching since 1984. His main
interests are power electronics and power quality. Dr. Pomilio was the President of the Brazilian Power
Electronics Society in 2000–2002 and a member of the Administrative Committee of the IEEE Power
Electronics Society in 1997–2002. He was Associate Editor of the IEEE TRANSACTIONS ON POWER
ELECTRONICS in 2003-2018.
Adaptive Control Techniques for Grid-Integrated Power Electronics Converters
Nowadays, the power systems are submitted to current and voltage harmonics due to the increased presence of nonlinear loads and the wide use of power inverters to interface solar and wind power plants. Nevertheless, these inverters can also be used to compensate current harmonics and improve the system power quality. Traditional harmonic detection methods extract all harmonic current information and the control tuning tends to be complex and less flexible. Therefore, adaptive current harmonic control strategy can be applied in grid-integrated power electronics converters. Voltage and current detection-based harmonic current compensation (VDB-HCC and CDB-HCC, respectively) strategies will be explored in this presentation. CDB-HCC strategies require converter hardware retrofit by inserting an extra current sensor to measure load or downstream grid currents. On the other hand, VDB-HCC strategies are straightforward solutions employing only embedded measurements used for protection, control, and synchronization purposes.
