Dynamic Security Assessment of the Ecuadorian Electric Power System using MATLAB - SIMULINK: Applications of Real Time Digital Simulation and Machine Learning


Overview

In recent years, Electric Power Systems have been operated closer to their operating limits. Under these conditions, certain unforeseen disturbances can produce cascading events that eventually lead the system to collapse. It is necessary to ensure that such disturbances do not affect the quality and continuity of the electricity service. In this sense, the need arises to develop mathematical models and practical tools that allow the design of a Self-Healing Grid as part of the concept of a Smart Grid, capable of carrying out reconfiguration functions and wide area control in real time, with the aim of reducing the risk of system collapse.

The dynamic security assessment (DSA) constitutes a fundamental part of this objective since it allows to decide and appropriately coordinate the most appropriate preventive or corrective control actions for the system. In this context, the National Electricity Operator of Ecuador, CENACE, has developed several methodologies aimed at performing DSA, which have been structured in MATLAB-SIMULINK, enhancing its functionality to implement Machine Learning algorithms, as well as its potential to interact with the OPAL-RT Real Time Digital Simulator.

This presentation shows a summary of the methodologies developed, the results obtained and outlines the future plans, based on the great potential of the analysis tool, for its implementation within the real-time operation processes.

About the Presenter

Jaime Cepeda, PhD
Centro Nacional de Control de la Energía (CENACE), Ecuador

Jaime C. Cepeda C. was born in 1981 in Latacunga, Ecuador. He got his Electrical Engineer degree, with the highest honors (Summa Cum Laude), in 2005 from National Polytechnic School, Quito, Ecuador. He worked in Ecuador at Schlumberger Surenco, and Consejo Nacional de Electricidad (CONELEC) from 2005 to 2009. During 2009 and 2013, he pursued his Ph.D. degree at Institute of Electrical Energy, National University of San Juan, San Juan, Argentina, favored with a scholarship from the German Academic Exchange Service (DAAD). He finally got the Doctor of Electrical Engineering degree, with the highest honors (Sobresaliente), in December, 2013. His research experience includes an internship at Institute of Electrical Power Systems, University Duisburg-Essen, Duisburg, Germany, as part of the DAAD scholarship between 2011 and 2012. His doctoral thesis was awarded by the “Domingo Faustino Sarmiento” 2014 prize in Argentina, and due to the same research, he was also recognized by the MIT Technology Review Innovators under 35 award in 2015. Nowadays, he works in Ecuador at National Electricity Operator CENACE as the Technical Development Manager, and he serves as part-time University Professor in Master and Doctoral Programs. In addition, he collaborates as Associate Editor of the International Scientific Journal “IET Generation, Transmission & Distribution”.

His special fields of interest comprise power system modelling, off-line and real-time digital simulation, power system stability analysis, security assessment, vulnerability assessment, synchrophasor measurement technology, wide area monitoring systems, and application of computational intelligence techniques (such as data mining, neural networks, fuzzy arithmetic, heuristic optimization, among others) into analysis of power systems.
