Stan Pejovic
Ryerson's Centre for Urban Energy (CUE) announced the appointment of Stanislav Pejovic as visiting fellow.
Dr. Pejovic has been teaching at the University of Toronto and Ryerson University since 2002, lecturing on specialized subjects related to energy, design of power plants, thermodynamics, physics, fluid mechanics and hydraulic transient analysis (waterhammer, vibrations, hydraulic vibrations, stability, resonance in technical systems and human blood vessels). He has also been visiting professor at the University of Singapore, and universities in Hong Kong, Sarajevo and Skopje, Nis, to name a few.
A world-renowned specialist in research, development, design, construction, commissioning, maintenance, troubleshooting and review of electric plants, hydraulic systems, pumps and turbines, Dr. Pejovic is also an expert in the complex thermal and nuclear plant systems. He is the author of several books and textbooks and a co-author of "The Guide to Hydropower Mechanical Design", prepared by ASME Hydro Power Technical Committee, as well as "Guidelines to Hydraulic Transient Analysis". As a consulting engineer on design, construction, on-site and model tests of power plants and computer simulation of transient and hydraulic vibration of many systems, Dr. Pejovic has been involved in projects in the U.S., Canada, Iran and the former Yugoslavia. He is currently a licensed professional engineer in Ontario.
Dr. Pejovic joins other recently appointed visiting fellows in CUE who are working with faculty and student research teams to find innovative, next-generation solutions to keep urban cities powered in the future.
Hydropower provides 20 per cent of the world's energy and is the fourth largest energy source for electricity production, after fossil fuels (coal, oil and gas). Dr. Pejovic's CUE research will examine how part of power requirements could be met not only through hydropower generation, but also through hydro and pumped storage which harnesses the gravitational potential energy of accumulated water. Pumped-storage hydroelectricity is a type of hydroelectric power generation used by some power plants for load balancing. The method stores energy in the form of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost off-peak electric power is used to run the pumps. During periods of high electrical demand, the stored water is released through turbines.
Given that electricity is impossible to accumulate, energy consumption from a grid must always be equal to energy delivered by generators. If this is not the case, the frequency and voltage fluctuate causing severe disturbances of supply/load balance, with potential for system collapse, expensive blackouts or brownouts. Pumped storage of energy represents a potentially significant environmentally clean load that may help compensate the need to limit wind power output. Dr. Pejovic will also assess how production and consumption can be optimized to improve efficiency, costs reduction, greenhouse gas and pollution reduction, blackout prevention, profits and consumer pricing.
Dr. Pejovic was born in Belgrade, Serbia, and received his PhD from the University of Belgrade. He served in various positions at the University, including professor for the department of mechanical engineering. He has also served as principal investigator and project manager, department of mechanics, Mathematical Institute of Serbian Academy of Sciences and Arts, in Belgrade.
