Techno-Economic Analysis and Optimal Operation of a Hydrogen Refueling Station Providing Frequency Ancillary Services

Techno-Economic Analysis of Hydrogen Production by Gasification of Biomass

Approach • Determine the cost and availability of the three candidate biomass feedstocks. • Design a process scheme for the production of hydrogen. • Determine optimal hydrogen production through the testing of various simulation cases. • Analyze research and simulation results to determine technical and economic feasibility. • Determine the commercialization barriers to the production of hydro...

Explaining Inefficiencies in Buildings Providing Ancillary Services

In a power system, having a high level of renewable energy penetration requires a large amount of ancillary services to balance the supply and demand in real time. Commercial buildings have significant thermal capacity and so offer large potential for providing such services. Recent research has shown that the power consumption of the Heating, Ventilation, and Air Conditioning (HVAC) system can...

Economic Advantages of Office Buildings Providing Ancillary Services with Intraday Participation

Controlling the consumption profile of office buildings can be used to provide balancing services to the power grid at a financial benefit without violating its thermal comfort constraints. The economic advantage of such a service is a reduction in the total operating cost, but also an increase in average occupants’ comfort when using our control scheme. We study these effects for the case of p...
