智能用电管理系统在高校中的应用

Intelligent Energy Management of Loads on Campus Considering Participation in Demand Response Program

智能电网和分布式能源微电网的发展促进了学校智能用电的应用,学校可对公共教学楼、宿舍等耗电量较大的建筑物进行智能用电管理。建立了学校不同类型用电管理系统框架,分别构建了教学设备、温控设备和PV系统的负荷模型,考虑需求响应的学校智能用电管理系统架构,包括用电管理模块和考虑上网的光伏发电管理模块,以教学设备、办公楼用电负荷为例对学校智能用电管理系统进行说明,并分析用电响应情况和经济效益。

With the development of smart grids and promotion of demand responses,intelligent energy management at the demand side attracted extensive attention. The intelligent system application makes it a good choice for implementing intelligent energy management in the university building. The structure of intelligent industrial energy management system is established at first,with different types of power demands and management of photovoltaic power generation taken into consideration. Then,based on the state task network,power demand models are established for teaching devices and temperature-controlled devices with thermal comfort of the production environment considered. On this basis, an optimal operation model of the intelligent energy management system is presented with the energy-purchasing cost and energy-selling income of the industrial load concerned taken into account. Finally,the typical load on campus is employed to present the right of the method,and its demand response performance and benefits of the intelligent energy management system are addressed as well.
