直流供电建筑与智能微网整合研究中美合作成果及展望

Achievements and Prospects of Sino-US Research Cooperation on Direct Current Power Supply in Buildings and its Integration with Smart Grid

本文介绍了中美清洁能源联合研究中心建筑节能合作--净零能耗建筑关键技术研究与示范项目中直流供电建筑与智能微网整合研究课题的研究成果,课题通过仿真对比、实验研究、示范应用等方法研究了建筑直流供电和分布式蓄电技术,以期解决城市电力负荷的峰谷差、电源和电网低负荷率时间长效率低以及可再生能源的充分消纳等问题。

This Article introduces the research achievements and prospects of the subtask of Direct Current Power(DC)Supply in Buildings and its Integration with mart Grid in the Sino-US research cooperation project on Key Technologies and Demonstration of Net Zero Energy Buildings.The research used simulation,experiment,and demonstration to develop the technologies of direct current power supply and distributed electricity storage in buildings in order to solve the problems of big power demand difference between peak and valley,low efficiency and long-time running of low load ratio,inadequately acceptance of renewable energy,etc.
