报告题目：Creating Power System Resources from DistributedEnergy
报告人：By Liuchen Chang ，University of New Brunswick,Fredericton, Canada
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.
