SEMINAR: Power System Flexibility Using Demand Response Programs
PRESENTER: Dr. Jamshid Aghaei (Associate Prof. of Shiraz University of Technology, Shiraz, Iran)
WHEN: Monday 31 August 2015, 11 am – 12 noon
ABSTRACT: Flexibility describes the system ability to cope with events that may cause imbalance between electricity supply and demand while maintaining the system reliability in a cost-effective manner. Flexibility has always been supposed in the power systems to provide for unexpected generator outages and demand uncertainty and variability. The large-scale wind power integration challenges this traditional well-adapted system by increasing the level of uncertainty and variability in the system.
The flexibility is defined as the ability of a system to cope with uncertainties and variations in the generation and the demand, while maintaining the system reliability at minimum additional cost. Economically, providing flexibility results in additional cost and this cost should be constrained within a reasonable range. From a technical point of view, the flexibility of a system can usually be improved by the main resources as follows:
- Scheduling of flexible generating units
- Application of energy storage systems
- Benefit of interconnections
- Participation of demand response programs (DRPs)
Among many possible strategies for handling flexibility of the power systems in the presence of renewable energy sources, demand response (DR) is considered as a new paradigm for this lecture. Demand response can be defined as changes in electric use by demand-side resources from their normal consumption patterns in response to changes in the price of electricity, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized. Indeed, the DR can contribute to system flexibility through a number of possible programs. DRPs by decreasing/increasing the peak/valley demand periods and shifting energy from high demand to low demand periods contributes to lower the stress on highly inflexible base-loaded units (e.g., nuclear power plants) to reduce their production levels.
BIO: Dr. Jamshid Aghaei (Associate Prof. of Shiraz University of Technology, Shiraz, Iran) obtained his BSc degree Electrical Engineering from Power and Water University of Technology, Iran in 2003 and MSc and PhD degree in Electrical and Power Engineering from Iran University of Science and Technology in 2005 and 2009, respectively. Following his graduation he joined the Department of Electrical and Electronics Engineering, Shiraz University of Technology (SUTech) as an Assistant Prof. in 2010. Then he followed his collaboration with SUTech as an Associate Prof. He has lectured major subjects in the field of Electrical and Power Engineering, and worked on several research projects. He also participated in many of the research programs within the Center of Power System Studies at SUTech. Also, Dr. Aghaei was associated with the Iranian Association of Electrical and Electronic Engineers (IAEEE)-Fars Branch as Member of Board of Directors from 2010 to 2012. Dr. Aghaei supervised and co-supervised Postgraduate Students (Master Students and PhD) by Research and Training and Undergraduate Students for Project Dissertations and Presenting Power System Courses. He has so far authored and co-authored a sound number of papers published in Impact Factor Journals (more than 60 journal papers) and attended high standard academic Conferences and Exhibitions Nationally and Internationally (more than 20 conference papers). He is a Reviewer for a number of International Journals and Conferences and a member of IEEE and other International Professional Associations. Dr. Aghaei has training and working experience with various industries of Electrical Power Engineering in Iran. Previously, he is appointed as a Research Fellow at the School of Electrical, Computer and Telecommunications Engineering (SECTE) with the University of Wollongong to carry out large research projects in the area of "Integration of Renewable Energy Sources to Distribution Network". Recently, he received Australian Endeavour Research Fellowship Award 2015. His employment and research experience includes Power System Operation and Planning; Renewable Energy and Microgrid Power System; and Application of Optimization in Power Systems Issues.
