DC Microgrid Experimental System at KIT Hakusan-roku Campus for Regional Areas

We describe our DC Microgrid experimental system at Kanazawa Institute of Technology (KIT) Hakusan-roku campus located at regional area of Hakusan city in Japan. Our experimental system is at the first stage of our roadmap in which our final goal is to construct a DC Microgrid network system in all of our campus. This system consists of DC bus, PV, battery, EV and a biomass system which is directly connected to DC bus. We describe backgrounds the reason why we choose DC system for our Microgrid. Then, we show the overview of system configuration and the concept of system control method that is composed by three-layer hybrid strategy using heat and electricity. The DC system which is the electrical part of our Microgrid is controlled by distributed way using equal incremental charge loading method.
