A NEW APPROACH FOR ASSESSMENT OF HYDROPOWER SYSTEM SAFETY

Slobodan P. Simonovic

Hydropower infrastructure systems are highly complex, high consequence structures which must be operated safely to avoid catastrophic impacts to human life, the environment and the economy. It is critical that dam safety practitioners have an in-depth understanding of how these systems function under the full range of operating conditions in order to ensure the appropriate measures are taken to reduce system vulnerability. Dynamic resilience offers a unique perspective about system behaviour by integrating system performance and adaptive capacity over time from the beginning of an undesirable event to full system recovery. System dynamics simulation allows modellers to simulate the dynamic interactions among the complex arrangement of system components, providing outputs of system performance over time that can be used to estimate dynamic resilience. This lecture presents the framework for a modelling approach that can be used to simulate the full range of potential operating conditions for a hydropower infrastructure system. Details of the generic hydropower infrastructure system simulation model are provided. A case study is used to evaluate potential system outcomes in response to an earthquake, with two system safety performance measures shown that could be used to estimate dynamic resilience. Results indicate that the simulation model is able to provide a detailed assessment of system performance measures that could be used to estimate dynamic resilience with respect to dam safety. A comparison of operational and upgrade strategies is shown to demonstrate the utility of the model for comparing various operational response strategies, capital upgrade alternatives and maintenance regimes.

Slobodan P. Simonovic is globally recognized for his unique interdisciplinary research in Systems Analysis  and the development of deterministic and stochastic simulation, optimization, multi criteria analysis, and other decision-making methodologies  for addressing challenging system of systems problems lying at the confluence of society, technology and the environment. His research has been applied with a sustainable development perspective in water resources management, hydrology, energy, climate change and public infrastructure. His main contributions include modelling risk and resilience of complex systems.  Professor Simonovic has influenced academia, industry and government via university teaching, publication of leading-edge research, mentoring of young people, delivering stimulating research seminars at institutions around the world, carrying out joint research projects, and consulting work. He has received awards for excellence in teaching, research and outreach. Dr. Simonovic has published over 530 professional publications (219 in peer reviewed Journals) and three major textbooks. He has been inducted to the Canadian Academy of Engineering in June of 2013.
