By Dr. Carlos Moreira, Faculty of Engineering, University of Porto, Portugal.
Microgrids (MG) are extremely flexible low voltage (LV) networks capable of operating interconnected with the upstream medium voltage (MV) network or autonomously (islanded) through the appropriated coordination of the locally available resources. During autonomous operation, MG operation is supported by controllers hierarchically organized to provide primary and secondary frequency regulation. The presentation focus on the experimental validation of MG autonomous operation conditions while considering coordinated control strategies exploiting the role of Electric Vehicles (EV), storage devices, microgeneration units and responsive loads in order to ensure a seamless transition to islanding mode. The development and validation of MG service restoration procedures will be also addressed.
Carlos Moreira graduated in Electrical Engineering in the Faculty of Engineering of the University of Porto – FEUP (2003), and completed his PhD in Power Systems in November 2008, also from the University of Porto.
He is member of the Centre for Power and Energy Systems of INESC TEC since September 2003. He is the “Network Studies and RES & DER Integration” Area leader in the Centre for Power and Energy Systems of INESC TEC since September 2015. In February 2009 he joined the Department of Electrical Engineering of FEUP as Assistant Professor.
He lead the consultancy activities for ENERCON between 2008 and 2012 concerning wind farms connection in Portugal, being responsible for the connection studies of about 1200 MW of wind farms. In 2011-2012, he was responsible for the research team in charge of developing a study for the Portuguese Transmission System Operator (REN) dealing with transient stability studies in the Portuguese transmission grid in scenarios with large share of wind power and involving the sizing and sitting of FACTS devices for improving system security in case of severe disturbances. Regarding research activities in off-shore wind power and multi-terminal HVDC grid operational and control issues, he was responsible from the INESC TEC research team participating in the European project TWENTIES (Transmission system operation with large penetration of Wind and other renewable Electricity sources in Networks by means of innovative Tools and Integrated Energy Solutions). He was responsible for the INESC Porto team involved in the FP7 funded project “HYPERBOLE – HYdropower plants PERformance and flexiBle Operation towards Lean integration of new renewable Energies”, contract number 608532. He is also the principal investigator of the project “COMUTE-DC”, funded by the Portuguese Foundation for Science and Technology, and intended to develop a laboratory scale platform for DC grids exploiting power-hardware-in-the-loop concepts.
His main domains of research are presently related with large scale integration of renewable power sources in isolated and interconnected power systems, power system dynamics and microgrids.
