Research Project Summary Information



Demonstration of OpenADR, a Smart Grid pricing and demand response data protocol, in NYC buildings.(20723)

Lawrence Berkeley National Laboratory

Background

Commercial buildings account for a large portion of NYS summertime peak demand that occurs in a relatively few hours each year. Based on research in California, it is hypothesized that NYS commercial buildings with advanced energy control technologies and strategies may reduce a building’s peak demand 10-15%. Seventy percent of all the commercial buildings over 50,000 square-feet have existing controls systems that may be able to implement advanced energy control strategies that would reduce bills, peak demand, and costs to the electric grid. Advanced energy control strategies can be used for daily load management and during demand response (DR) events, but for these strategies to be effective and reliable for price and demand response they must be automated. An electric grid where load actively responds to dynamic price and/or DR event signals better balances supply with demand and ensures reliability. Therefore, buildings should be able to electronically receive prices (capacity, delviery, energy, etc.) and/or demand response signals, and optimize an automatic response by the building’s systems. To facilitate buildings’ automated response, the electric grid should provide standard price signals electronically and integrate a building’s automated demand response capabilities for consistent, reliable, measurable performance. DOE and NIST are developing price and demand response data exchange standards intended to facilitate automated price and DR event response from buildings.

Project Description

This project examines the use of a standards-based interoperable information exchange, Open Automated Demand Response (aka OpenADR), between a building’s control system and the utility, energy supplier, curtailment service provider and ISO in NYS. The purpose of this project is to demonstrate how advanced building controls and OpenADR can facilitate automated price and demand response from commercial buildings in NYC. OpenADR is one of the 70 NIST identified ‘smart grid’ standards. This project seeks to build the confidence of building operators, control vendors, utilities and grid operators, that automation can make demand response reliable and sustainable. Approximately five commercial facilities in NYC will be equipped with the capabilities for automatic load management and curtailment and be provided price and DR signals electronically in the OpenADR format. The research team will develop HVAC control and curtailment algorithms that allow these buildings to provide demand response during NY’s humid summer-time peak, while minimizing electricity costs and maximizing DR participation. The project will evaluate how different buildings can respond in their daily operations at peak and throughout the year. Throughout the test period, the project team will collect trend logs from the building controls systems and electric demand data from the meter to evaluate the performance of the sites and make iterative changes to the control algorithms.

Benefits

This project will: • synthesize appropriate electricity price and DR signals typical in NYC (i.e. flat, day-ahead and indexed energy, demand/delivery, capacity and DR) for integration into building controls via the OpenADR standard, • characterize load flexibility and thermal capabilities of the NYC commercial buildings in the demonstration, • develop HVAC load control strategies to minimize energy cost from day-ahead hourly prices and minimize peak demand in NYC's humid heat waves(i.e. precooling), • evaluate the potential of demonstration sites to provide higher value DR services such as dispatchable, fast acting, ancillary services (i.e. 10 minute spinning reserves) or targeted circuit load relief, and • demonstrate an automated manner of commercial buildings DR integration as a utility and ISO resource.
