Research on distributed photovoltaic access based on low-voltage distribution Internet of Things(IOT)
Aiming at the problem that distributed PV information cannot be uploaded to the distribution network operation system in real time due to the low degree of automation and weak sensing ability of the low-voltage grid,by analyzing the reasons for voltage rise caused by distributed PV access,it is proposed to build a low-voltage distribution Internet of Things platform,establish a cloud-pipe-side-end system framework,realize the function of automatic recognition of the topology of low-voltage grids,and establish a voltage regulation strategy for low-voltage grids.The establishment of a platform for coordinated operation of station area source grid,load and storage based on LV distribution IoT is conducive to improving the operation capability of the station area and the ability to support the highly elastic power grid.
