Using flexible HVAC power consumption of commercial buildings for regulation service to the grid Technical Report

چکیده
We study providing ancillary service to the power grid by using the flexibility of HVAC (Heating, Ventilation, Air Conditioning) systems in commercial buildings. The building HVAC system’s thermal and power consumption models are constructed and key model parameters are estimated from measure data from Pugh Hall of University of Florida. We develop a method for optimal output tracking of a time-varying regulation signal by manipulating the fan speed of the HVAC system. Due to the large thermal capacity of commercial building and its flexibility of HVAC systems, we show that it is highly feasible for commercial buildings to provide ancillary service to the grid by dynamically adjust its fan power consumption without noticeably impacting the building inside environment and the comfort of occupants. In addition, numerical experiments are conducted to show that for a typical HVAC system, it is able to provide about 10% of its fan power capacity for frequency regulation, with the building inside temperature deviation less than 0.2 ◦C.

Commercial building HVAC system in power grid ancillary services
With the introduction of volatile renewable energy sources into the grid, the need for inexpensive ancillary service increases. We propose a method to provide ancillary service by using the flexibility of demand in commercial building HVAC (heating, ventilation, air-conditioning) systems. In particular, we show how a regulation command transmitted by a balancing authority can be tracked by vary...
متن کاملFlexibility of Commercial Building HVAC Fan as Ancillary Service for Smart Grid
In this paper, we model energy use in commercial buildings using empirical data captured through sMAP, a campus building data portal at UC Berkeley. We conduct at-scale experiments in a newly constructed building on campus. By modulating the supply duct static pressure (SDSP) for the main supply air duct, we induce a response on the main supply fan and determine how much ancillary power flexibi...
متن کاملBuildingSherlock: Fault Management Framework for HVAC Systems in Commercial Buildings
HVAC systems constitute ∼ 40% of energy in commercial buildings, and faults in HVAC account for 5% to 20% of its energy consumption. Typically, HVAC in modern buildings are managed using Building Managing Systems (BMS), and fault detection is one of the essential services provided by BMS to keep HVAC operational. We study the fault management practices followed in real commercial buildings, and...

It now seems inevitable that power grids of the future will be massive stochastic networks whose nodes are themselves microgrids comprising generation and storage units, inverters and power conditioning elements, together with controllable aggregations of appliances and other load classes. There will be significant amounts of power coming from wind, solar, and cogeneration enabled by combined h...
