Description

This paper is part one of a two-part paper that presents an excerpt of the ASHRAE research project 1011-RP, entitled Utility/Energy Management and Controls System (EMCS) Communication Protocol Requirements. The focus of this project was on the definition of energy-related information services and the analysis of data requirements to enable these services. This paper presents a description of the following nine information services: (1) revenue meter reading (electricity, gas,water, and heating and cooling energy); (2) quality of service monitoring; (3) real-time pricing transmission; (4) load management service; (5) on-site generation supervisory control; (6) energy efficiency monitoring; (7) weather reporting and forecasting services; (8) indoor air quality monitoring; and (9) dynamic demand bidding into a power exchange.

This paper further discusses the fundamental characteristics of interoperability in diverse network environments and the three levels of (1) communication, (2) application, and (3) scenario interoperability. This paper will present the concept of topology independence for messaging in wide area network applications and the associated advantages for the implementation of the above information services.

Part 2 of the paper introduces the common application service models (CASM) as a data modeling framework for achieving topology independence (CASM 1998). A detailed data model for a real-time pricing rate schedule will be presented and further described by means of an example of a real-time pricing communication. The part two paper will conclude with an approach tomap data objects defined for the above services from a CASM framework to the BACnet protocol.
