Distributed power generation systems using renewable resources are increasingly deployed, but without proper control they can cause grid problems, so careful consideration of generation, safety, and synchronization is required before connecting to the utility network. This study addresses grid synchronization challenges in distributed systems and proposes new solutions to optimize synchronization under distorted grid conditions. The authors provide an overview of synchronization methods and their key characteristics, and evaluate them through simulation and experimental tests under voltage dips, harmonics, and notches. Simulation and experimental results show how the synchronization methods perform under voltage dips, harmonics, and notches, highlighting their behavior in distorted grid conditions.
Nowadays, it is a general trend to increase the electricity production using distributed power generation systems (DPGS) based on renewable energy resources such as wind, sun or hydrogen. Jf these systems are not properly controlled, their connection to the utility network can generate problems on the grid side. Therefore, considerations about power generation, safe running and grid synchronization must be done before connecting these systems to the utility network. This paper is mainly dealing with the grid synchronization issues of distributed systems. An overview of the synchronization methods as well as their major characteristics is given. New solutions to optimize the synchronization methods when running on distorted grid conditions are discussed. Simulation and experimental results are used to evaluate the behavior of the synchronization methods under different kind of grid disturbances such as voltage dips, harmonics and notches.
