Understanding Power Systems with the Power of the Brain

ABSTRACT

Seeing events in 2D pictures with deep learning applied to visual cortex neural architectures: a tool of the future for power system control centers.

Phasor Measurement Units (PMUs) are being installed and then control centres are becoming flooded with a tsunami of data. The information contained in such big data environment is largely left unused, but the PMU data contain signatures of dynamic events and the prompt recognition of such events could lead to better alarm processing, more accurate event diagnosis and possibly to preventive problem detection. The talk will reveal the most recent advances in dealing with this big data problem through deep learning with CNNs (Convolutional Neural Networks), whose architecture mimics the visual cortex of the human brain, and computing with GPUs (Graphic Processing Units). PMU real data from Brazil will show how the transformation of PMU time domain measurements of system frequency into 2D colour pictures allows a 100% success, with a CNN, in recognizing and classifying dynamic events such as, for example, generator or line tripping, load disconnection of inter-area oscillation.

VLADIMIRO MIRANDA was born in Porto, Portugal. He graduated in Electrical Engineering in 1977 and received the Ph.D. degree in Electrical Engineering from FEUP, the Faculty of Engineering of the University of Porto, Portugal, in 1982. He currently holds the following positions: Full Professor (Professor Catedrático) at FEUP, Director/Member of the Board of INESC TEC, an R&D private non-profit institution in Portugal, Director-President of INESC P&D Brasil, an R&D private non-profit organization with headquarters in São Paulo, Brazil, Member of the Board of OCEANUS – marine research and innovation, University of Porto, Portugal.

He is also International Academic Advisor of the Polytechnic University of Hong Kong, Member of the Scientific Council of IRESEN, Ministry of Energy, Morocco, member of the Scientific Council of the Chemical and Biologic Defense Laboratory of the Portuguese Army and Honorary Visiting Professor of the University of Novi Sad, Serbia, as well as member of the International Scientific Advisory Board of the research institutes IIT – Instituto de Investigación Tecnológica, Madrid, Spain, and IEE – Instituto de Energía Eléctrica, San Juan, Argentina.
