【主講人簡介】
Received the B.Sc. degree in 1988 from the State University of Rio de Janeiro, Brazil, the M.Sc. degree in 1991 from the Catholic University of Rio de Janeiro, Brazil, and the Ph.D. degree in 1994 from Rensselaer Polytechnic Institute, Troy, NY, USA, all in Electrical Engineering (EE) with emphasis on Electric Power Engineering. In 2006, he was on sabbatical leave as a Visiting Fellow at Centro Elettrotecnico Esperimentale Italiano (CESI), Milan, Italy. Since 1995, he has been with the EE Department of the Federal University of Rio de Janeiro / COPPE, Brazil, where he is currently a Professor, and head of the
Power Systems Group and Laboratory. He is the vice-chair of the IEEE PES Power System Dynamic Performance Committee, and member of the Administrative Committee of CIGRé-Brasil. He was president of the IEEE Rio de Janeiro Section in 2008-2009, and Associate Editor of the IEEE Transactions on Power Systems in 2016-2020. His research interests include power system dynamics, protections and controls, robust control design, distributed energy resources and hybrid AC/DC networks.
【講座內(nèi)容】
Widely recognized as a hydroelectric powerhouse, Brazil has historically relied on hydropower to supply over 90% of its annual electricity demand. In recent years, however, this dominance has declined as wind and solar generation have grown significantly. Having a continental size, the Brazilian Interconnected Power System (BIPS) relies heavily on a large network of AC transmission lines, plus 6 HVDC links with a DC transmission capacity of 20 GW in total. Of these 6 links, 4 are radial connections from generation locations, while the two most recent put in service and another one under construction are embedded in the BIPS. The BIPS is divided into four geo-electric regions with different seasonal wet and dry conditions, all synchronously connected by extra high voltage AC lines. This natural characteristic emphasizes the importance of the transmission system among the regions. The fast-paced growth of wind and solar generation is concentrated in one of the geo-electric regions, the northeast region, further emphasizing the importance of the transmission system. Due to this growth, Brazil has decided to increase the participation of HVDC transmission between the geo-electric regions, to transmit the surplus wind and solar generation to the large load centers in the southeast region. The growth of renewable energy with its intermittent characteristics, paired with market-based generation dispatch, has put new demands on the control systems of embedded HVDC links. These factors call for an HVDC power flow control strategy that actively adapts to the inherent fluctuations in generation and load while preventing adverse effects such as loop power flows and increased losses. To mitigate loop power flows in the hybrid AC–DC network, the embedded HVDC link employs a time-synchronized angle difference control scheme between its rectifier and inverter terminals. The study presents the outcomes of this prospective control approach, which adapts DC power flow setpoints in real time according to variations in solar and wind generation dispatch.
