Implementation of Wireless Remote Monitoring and Control of Solar Photovoltaic (PV) System

This paper describes the implementation of a wireless remote monitoring and control system of a solar photovoltaic distributed generator (PV-DG) for microgrids applications. To this aim, a small-scale PV-DG system is implemented using a 1.28 kWp assembly of PV polycrystalline modules connected to a single-phase utility grid through a commercial inverter. Then, a flexible, robust and reliable measurement and control system based on wireless sensor network (WSN) architecture is deployed. The wireless communication technology utilizes a full duplex digital system using the ZigBee protocol, based on the IEEE 802.15.4 standard for Wireless Personal Area Network (WPAN). The supervisory control system is implemented on a digital signal processor (DSP) and a human-machine interface (HMI) software is developed for interacting with and managing remote sensor systems (RSSs).
