Synchronization of Grid-Tie Inverters Using 802.11ah

Distributed generators systems are the latest trend in power generation due to their scalability. However, many issues should be addressed to improve the system's reliability. Communication, synchronization, and islanding are major challenges that need to be tackled to improve the overall performance. This paper presents a wireless system based on IEEE802.11ah wide range protocol as a novel solution for communication and synchronization in grid-tie inverters environment. The protocol is designed to meet the timing constraints and requirements of IEC international standard 61727. Having several grid-tie inverters, the system will be able to communicate with the local distribution generator and exchange data with all nodes, hence controlling the inverters operation.
