Group consensus protocol-based power line communication wide coverage time synchronization

Abstract

High-precision time synchronization of each node in the distribution network is a critical technology supporting for distributed photovoltaic (PV) services. However, traditional time synchronization method has high costs and low coverage applying in the distribution network, which hinders the implementation of distributed PV services. Aiming at the above problems, we propose a group consensus protocol-based power line communication (PLC) wide coverage time synchronization method. First, the PLC wide coverage clock synchronization architecture is illustrated. Then, a group consensus protocol-based clock synchronization algorithm is proposed to achieve fast convergence and high precision time synchronization. Finally, the effectiveness of the proposed algorithm is verified by simulation.
