Due to the myriad of devices and loads that are collected under the Commercial Building Energy Management Systems (EMS) focused on the Industry 4.0 paradigm, it is important to ensure their proper electrical operation. The power quality here requires a granular monitoring approach, reaching a point where each device connected to the microgrid can diagnose that its power supply is optimal. Otherwise, it can participate cooperatively in decision-making to avoid faults or blackouts in the microgrid. In this work, we present a novel Controller to make smart appliances responsive to the grid, either autonomously or managed under Demand Response policies. Apart from a TRIAC acting as an AC switch, the main advantage lies in its embedded Power quality internet of things (IoT) sensor. It measures a wide spectrum of electrical disturbances, far exceeding the capabilities of other solutions such as the Grid Friendly Appliance Controller, so it is possible to customize a battery of alarms at will, in e.g. according to IEEE-1547. Moreover, although it can act autonomously, its main mission will be to act in coordination, either cooperatively or under the supervision of the EMS. The IoT platform where the controller would be incorporated is also presented. Finally, two case studies are presented to show their capabilities. With the integration in the microgrid of these distributed submetering systems, with wireless connectivity and under standard communication protocols, a further step will be taken in the development of the Digital Energy Platform, and the improvement of the quality of consumption by the user, as well as information support systems for smart meters.
