Demand Response Research Projects
With the help of PIER, Southern California Edison and the California Lighting Technology Center have performed a study on communications and lighting control technologies and identified the internet as the best medium for a lighting demand response program. When this was tested with various types of lighting control systems it was found that all the systems worked well in a multitude of demand response scenarios. This study led to the creation of the California Lighting Controls Training Program. See the final report.
Lighting California's Future was the California Energy Commission's $3.7 million Public Interest Energy Research Program focused on lighting technologies for buildings. The project on Cost-Effective Demand Response sought to introduce a novel demand response lighting control technology that can easily be retrofitted to existing buildings. The new system would be capable of receiving a utility demand reduction signal and transmitting, over the building power lines, a load shed signal to multiple receiver devices, which are installed at light switches that are deemed ideal to shed lighting load. The report concludes that the cost-effective demand response system needs to be further modified at the component level. NEV Electronics plans to continue development and testing of the system with private funding.
The development of the Open Automated Demand Response Communications Specification, also known as OpenADR or Open Auto-DR, began in 2002 following the California electricity crisis. This specification describes an open standards-based communications data model designed to promote common information exchange between the utility or Independent System Operator and electric customers using demand response price and reliability signals. OpenADR is one element of the Smart Grid information and communications technologies that are being developed to improve optimization between electric supply and demand. The intention of the open automated demand response communications data model is to provide interoperable signals to building and industrial control systems that are pre-programmed to take action based on a demand response signal, enabling a demand response event to be fully automated, with no manual intervention. The concept of an open specification is intended to allow anyone to implement the signaling systems, the automation server, or the automation clients. This communication specification is an essential enabling technology for California's future electrical grid. OpenADR will provide benefits to California by both increasing the number of facilities that participate in demand response, and reducing the cost to conduct frequent and persistent participation in demand response. The work has been carried out by the Demand Response Research Center (DRRC), which is managed by Lawrence Berkeley National Laboratory.
