Development of Experimental Load Management System for Nearly Zero-Energy Building

Over two third of total electricity produced are consumed by residential and commercial buildings. According to this the nearly zero-energy building (NZEB) with local renewable power sources will play important role to reduce greenhouse gases. Local and intermittent renewable power generation is challenge for power quality and supply reliability of NZEB. It means higher demand for an Energy Management System (EMS) to provide power quality and balance between load and generation. This paper gives a brief overview of EMS for residential buildings. To test an EMS, the behavior of NZEB must be simulated in the laboratory. For this purpose, an experimental system was developed which includes variable load and its control as a part of EMS. Two load simulation methods for load management were studied and experimentally verified.
