At present, China is in the process of reforming the electric power system. The reform of the power system has a significant impact on the investment and construction of power distribution network. Therefore it is indispensable to focus on fine management of the operation and maintenance of equipment.
The development of intelligent operation and maintenance technology for power systems outside China is rapid too. They have focused more attention on new energy power systems, so they have certain technical advantages. But their software industry is also still at the early stage of innovating and adopting AIOps solutions.
Therefore, the issue of voltage exceeding limits resulting from the connection of distributed PV power generation to DNs can be avoided, leading to further increased network hosting capacity of the distributed PV power generation.
