The Design Of Power Demand Response Terminal For Intelligent Building

Intelligent electrical building as a key element of smart grid power consume segment, which most important features is energy conservation. By using advanced computer control technology, management software and program of energy conservation systems, integrated energy management systems can effectively improve the energy efficiency of buildings. But the lack of interaction with the grid side, makes the acquisition of the information of power grid not in the real-time, and can’t respond positively to the demand-side management of power grid. To insert the intelligent building into the smart grid, combining demand response technology, demand response terminal of intelligent building is designed in this paper. This terminal can make intelligent building response to the grid strategy automatically.First, based on the design of energy management system of intelligent buildings, energy management systems architecture, network architecture, communication methods and functions are summarized, and concepts which related to the electricity demand response technology are researched.Then, based on the smart grid method following IEC/PAS 62559 requirements of energy systems, by analyzing the demands of main participants and users who participated in demand response of smart buildings, concept model and physical deployment of demand response system are proposed. According to OSI and SGAM, hierarchical model of smart building’s demand response terminal is proposed,and be divided into four layers including basic platform layer, communication layer, the information layer and functional layer, to achieve information exchange between the electrical equipment and systems. According to the requirements of the system software and hardware architecture are designed.On the basis of framework design, using functional diversity methods, six functional sets include of terminal data communications, information management, transaction management, automated response, benefit assessment, security management are designed in detail. Data collection, information exchange, security certification, policy control, implementing impact assessment, and distributed energy management for intelligent building users are achieved.Finally, in order to achieve a two-way interactive functions of DR terminal, using C/S exchange mode, technology of middle-libraries and Web-Service interface for the required information exchange interface, standardizing information exchange, the interoperation between grid and intelligent building user is achieved.
