Monitoring System for Tracking a PV Generator in an Experimental Smart Microgrid: An Open-Source Solution

Smart grids and smart microgrids (SMGs) require proper monitoring for their operation. To this end, measuring, data acquisition, storage, as well remote online visualization of real-time information, must be performed using suitable equipment. An experimental SMG is being deployed that combines photovoltaics the energy carrier hydrogen through interconnection photovoltaic panels, electrolyser, fuel cell, load around a voltage bus powered by lithium battery. This paper presents system based on open-source hardware software tracking temperature generator in such an SMG. In fact, increases PV modules lead to decrease efficiency, so parameter needs measured order monitor evaluate Specifically, developed consists network digital sensors connected Arduino microcontroller, which feeds acquired Raspberry Pi microcomputer. The latter accessed cloud-enabled user/operator interface implemented Grafana. expounded results are reported validate proposal.
