Fast Transactive Control For Frequency Regulation In Smart Grids With Demand Response And Energy Storage, Andrew Ly, Saeid Bashash

Faculty Research, Scholarly, and Creative Activity

This paper proposes a framework for controlling grid frequency by engaging the generation-side and demand-side resources simultaneously, via a fast transactive control approach. First, we use a proportional frequency-price relation to build and analyze a transactive frequency droop controller for a single-area power grid. Then, we develop a transactive demand response system by incorporating a large population of thermostatically controlled air conditioning loads. A proportional-integral controller is used to adjust the setpoint temperature of the air conditioners based on price variations. A battery storage system is then developed and augmented to the system to capture the energy arbitrage effects. A …

Meteorological Profiling In The Fire Environment Using Uas, Matthew J. Brewer, Craig B. Clements

Faculty Research, Scholarly, and Creative Activity

With the increase in commercially available small unmanned aircraft systems (UAS), new observations in extreme environments are becoming more obtainable. One such application is the fire environment, wherein measuring both fire and atmospheric properties are challenging. The Fire and Smoke Model Evaluation Experiment offered the unique opportunity of a large controlled wildfire, which allowed measurements that cannot generally be taken during an active wildfire. Fire–atmosphere interactions have typically been measured from stationary instrumented towers and by remote sensing systems such as lidar. Advances in UAS and compact meteorological instrumentation have allowed for small moving weather stations that can move with …

A Micro-Scale Analysis Of Cycling Demand, Safety, And Network Quality, Sherry Ryan, Ana Garate, Diane Foote

Mineta Transportation Institute

This research uses a unique database of cycling volumes from the San Diego region to estimate cycling demand and cycling collision models. Continuous cycling count data collected from 34 automated counters are used to extrapolate over 1,400 short duration counts to average annual daily bicycle volumes (AADB). Network characteristics, built environment, and socio-economic characteristics are primary independent variables employed in the modeling. A key contribution of this research is to incorporate both a whole-network measure (betweenness centrality) and a network quality measure (LTS) in estimating cycling volumes. This research also improves upon cycling risk assessment by using more rigorous exposure …
