SMART Power Flow Controllers – A Necessity for Future Power Grid

Level 1, Room 1.30 (Board Room) CQUniversity, Melbourne Campus, Melbourne

Abstract: Power flow control techniques have been practiced, from using inductors, capacitors, transformers and load tap changers in the earlier days of electrical engineering to power electronics-based solutions in recent years. Even though the costs and complexities of the available solutions vary widely, the basic underlying theory of power flow control is still the same as it has always been. The question is which solution one should employ. The answer depends on knowing what the true need is. The power industry’s pressing need for the most economical ways to transfer bulk power along a desired path may be met by building new transmission lines, which is a long and costly process. Alternately, it may be quicker and cheaper to utilize the existing transmission lines more efficiently. The key is to identify the underutilized transmission lines and harness their dormant capacities to increase the power flows to the lines’ thermal limits using the most cost-effective and time-tested solutions. The presentation is designed to provide the basic principles of power flow control theory, an overview of the most commonly used power flow controllers, and future trends. The audience will hear from an expert who actually designed and commissioned a number of power electronics based FACTS controllers since their inceptions in the 1990s. Speaker: Kalyan Sen is the President & Chief Technology Officer of Sen Engineering Solutions, Inc. ( that specializes in developing SMART power flow controllers—a functional requirements-based and cost-effective solution. Kalyan worked 33 years in academia and industry. He was a key member of the Flexible Alternating Current Transmission Systems (FACTS) development team at the Westinghouse Science & Technology Center for which he became a Westinghouse Fellow Engineer. He contributed to concept development, simulation, design, and commissioning of FACTS projects at Westinghouse. He conceived some of the basic concepts in power flow control technology for which he was elevated to the IEEE Fellow grade with the citation: for the development and application of power flow control technology. He is the Co-inventor of the Sen Transformer. Free Registration: Join the Event: Online zoom meeting link:    

Leading Women in Power Engineering Highlight Renewable Integration in WA Microgrids

Building 80, Level 2, Room 2 (80.2.2) RMIT, Melbourne, Australia

Abstract: In 2021 Alinga Energy Consulting was awarded a grant through the Regional and Remote Communities Reliability Fund – Microgrids to conduct energy feasibility studies for 5 Indigenous communities in Western Australia. Ruby Heard, electrical engineer and director of Alinga Energy Consulting, will present a case study on integrating renewable energy into an isolated, diesel powered network. The study modelled 3 options for incorporating solar PV and battery storage – household rooftop solar, community owned centralised assets and utility owned centralised assets. Ruby will share results of the techno-economic analysis as well as community perspectives and benefits.   Speaker: Ruby Heard is an electrical engineer from Melbourne, now based in Rockhampton Qld. She completed her undergraduate degree at Victoria University in 2010. Ruby then went on to be a building services engineer for Arup, designing electrical and lighting systems for local buildings such as 888 Collins St, Terminal 4 at Melbourne Airport and Mitcham Train Station as well as international projects including the Louvre in France. Ruby transferred to the Arup San Francisco office in 2015 to pursue a greater focus on renewable energy where she started to specialise in complex solar arrays and microgrids working predominantly with Google. She was awarded an Emerging Leader in Sustainability recognition by the Design Futures Council in 2017. In early 2018 Ruby left Arup to volunteer in Ethiopia for 6 months through Engineers Without Borders, to support the United Nations High Commissioner of Refugees (UNHCR) energy team to design and install solar mini-grids while training refugee cooperatives as solar technicians. In November 2018 Ruby returned to Australia and formed Alinga Energy Consulting to continue her work in the renewable energy and microgrid space with a focus on off-grid applications, remote Indigenous communities and islands. Ruby was awarded Young Engineer of the Year Victoria by Engineers Australia in 2019 and featured in EA’s centenary celebration of 100 engineers making a difference.

Automated Fault and Disturbance Analysis

Building 80, Level 2, Room 080.02.001, RMIT University (Melbourne City Campus) Building 80, Level 2, Room 080.02.001, RMIT University (Melbourne City Campus), Melbourne

Abstract: Power system experience faults and disturbances that may negatively affect its desired performance. Over the years many sources of data have been used to automate fault and disturbance detection, classification, and characterization with a goal of helping operators, planners and protection engineers in assuring timely manual or automated reaction to faults and disturbances, particularly if they are poised to endanger safe, reliable, and secure electric grid operation. The talk focuses on three key considerations when designing such automated systems: a) selection of sources of data, b) choices of algorithms for reaching the conclusions, and c) mitigation measure for preventing or reducing impacts of fault and disturbances. The data discussion differentiates between the time synchronized and unsynchronized field waveform recordings, and the use of data from relays, fault recorders and PMUs. The choices of algorithms depend on the purpose of the analysis, so the differentiation is made between post-mortem, online and predictive analysis. The mitigation measures depend on the goal of assisting operators and planers or designing IEDs for automated control to mitigate the fault and disturbance impacts. The talk ends with examples from T&D and DER applications. Speaker: Mladen Kezunovic has been with Texas A&M University, College Station, TX, USA, for over 35 years, where he holds titles of Regents Professor, Eugene E. Webb Professor, and Site Director of “Power Engineering Research Center” consortium. He is also the Principal of XpertPowerTM Associates, a consulting firm specializing in power system modeling and data analytics for the last 30 years. His expertise is in protective relaying, fault modeling, automated power system disturbance analysis, computational intelligence, data analytics, distributed energy resources, and smart grids. He has authored/co-authored over 600 papers, given over 120 seminars, invited lectures, and short courses, and consulted for over 50 companies worldwide. Dr. Kezunovic is an IEEE Life Fellow, and a CIGRE Fellow, Honorary and Distinguished Member. He is a Registered Professional Engineer in Texas. He is a member of the US National Academy of Engineering. Free Registration: Join the Event: Online zoom meeting link: Meeting ID: 849 2154 0195 Passcode: 41515361
