Energy saving IoT-based advanced load limiter

A load limiter is particularly needed in places like microgrid business centers because the load limit that the microgrid structure can handle must not be exceeded. This study aimed at keeping load variation under control by planning daytime load distribution using IoT-based energy measurement and central management software. By using IP-based smart meters and control methods to perform energy measurements, all loads on the microgrid can be loaded in a balanced manner from the centralized software. Moreover, load balance across the grid can be protected by shutting off the relevant overcurrent devices. By setting the load limits for certain zones at specific times of the day, both the electrical devices and the microgrid are safeguarded. In heating and cooling applications, when all components on the grid are overloading the microgrid, other electrical appliances are prevented from exceeding the permitted current limits. Thus, installation of the system results in energy saving and reduced costs. Details are shown in this study.
