The residential-level intelligent microgrid is generally considered as a small-scale electricity system that relies mostly on local solutions to reliable and economical operation for supply-demand balance while being conducive to its connected main grid. This paper aims to conceptualize the intelligent residential microgrid from the perspectives of system-level control and component-level reformation. In particular, a newly developed hardware-in-the-loop microgrid platform is presented, through which a recently proposed online scheduling algorithm namely CHASE (Competitive Heurist Algorithm Scheduling Algorithm for Energy-scheduling) has been confirmed to be feasible and effective. Towards component level, several implementations related to low-voltage-ride-through capability on the local generation side and frequency responsive control on the demand side are also presented. Experimental results exhibit the practical feasibility of the proposed intelligent microgrid concept.
