Abstract        

The penetrationof renewable energy systems has been increasing globally. The fluctuating powerproduction from renewable energy requires additional power system resources tobalance these fluctuations on top of load variations. These power systemresources have traditionally been supplied by dispatchable central generation plants,most are fossil fuel based. However, keeping building fossil fuel based centralgeneration plants is unsustainable. Various energy storage systems such aspumped hydro, compressed air, battery, flywheel and hydrogen systems as sourceshave been used in utilities. In addition to other limitations, costs are stillhigh for these available energy storage systems in utility applications. Dr.Chang will present an alternative and dispatchable resource for power systems, createdfrom distributed energy resources. The distributed energy resources includedistributed generators (wind, solar etc.), customer loads with storage capacityand batteries including electric vehicles. The customer loads have thermalenergy storage capacities, such as water heaters, electrical thermal storageunits, ice making units, HVACs, etc. With aggregated controls and virtual powerplants, the overall power consumed by these loads can be ramped up or rampeddown continuously without negative impact to the normal end use, similarly toother energy storage systems. Distributed generation systems, energy storagesystems, and direct load control systems thus form generalized energy storage capacityas alternative power system resources for ancillary services or/and peak loadshaving, which can enable integration of a high percentage of intermittentrenewable energy systems in utilities.      

Brief bio of LiuchenChang        

Dr. Liuchen Chang received his B.Sc. degree fromBeijing Jiaotong University in 1982, M.Sc. degree from China Academy of RailwaySciences in 2014 and Ph.D. degree from Queen’s University in 1991. He joinedthe faculty of University of New Brunswick in 1992 and is a professor inElectrical and Computer Engineering. He held the position of NSERC Chair inEnvironmental Design Engineering during 2001-2007, and was the PrincipalInvestigator of pan-Canadian Wind Energy Strategic Network (WESNet) during2008-2014. He was a recipient of CanWEA R.J. Templin Award in 2010 for hiscontribution in the development of wind energy technologies. He was the generalchair of the 2015 7th IEEE Energy Conversion Congress and Exposition (ECCE2015) in Montreal, Canada, and 2016 8th IEEE International Power Electronicsand Motion Control Conference - ECCE Asia (IPEMC 2016-ECCE Asia) in Hefei,China. He is a fellow of Canadian Academy of Engineering (FCAE) and a VicePresident of IEEE Power Electronics Society. He has published over 330 refereedtechnical papers in journals and conference proceedings. His expertise is in powerconverters, direct load controls and distributed generation systems.
