Operation and maintenance of distributed PV systems

Nowadays, grid operators usually require grid-connected photovoltaic systems to be irreversible, that is, the power generated by grid-connected photovoltaic systems is consumed by local consumers, and excess power is not allowed to be fed into the grid. The system can regulate power generation to prevent the grid-connected photovoltaic system from generating reverse power. Photovoltaics has become one of the most popular new energies in recent years, so a comprehensive solution for monitoring power generation and reverse flow in each part of the PV power distribution system is required for both distributed and centralized PV systems.
