An Interoperable Building Energy Management System with IEEE1888 Open Protocol for Peak-Load Shaving

A peak-load shaving is implemented for a Building Energy Management System (BEMS). The IEEE1888 open protocol is adopted to facilitate the interoperability capability through the TCP/IP network. The data structure is determined by the Facility Information Access Protocol (FIAP). The operation of equipped Battery Energy Storage System (BESS) is optimized from the analytical load-forecast model. The peak-load-shaving application is developed with a 15-minute on-line processing. The real-world BEMS is demonstrated by a test-bed building at Chulalongkorn University, Thailand; where the significant loads are the distributed air-conditioning systems. Experimental results are gathered; the work-day load forecast is conducted for two weeks and the optimized operation of a 5.76 kW/ 14.4 kWh BESS is examined accordingly, and up to 4 kW of peak load is successfully shaved out of 50-kW peak demand.
