According to the traditional distributed photovoltaic array, diesel generators, wind turbines, battery energy storage, loads and other energy equipment are independently connected to the traditional AC power grid through corresponding power electronic conversion devices, and are centrally managed by the central controller Scheduling, this kind of distributed energy is connected to the grid through the inverter device, and the DC load is powered by the rectifier device, which makes the complexity of the power grid surge
[0003] According to the traditional grid system connected by distributed photovoltaic arrays, when a device fails, it is necessary to isolate the connection of the grid for troubleshooting; when the device is expanded or updated, it is necessary to install the corresponding device separately and re-optimize the configuration of the entire system. Increased difficulty in operation and control
In particular, the intermittent nature of renewable energy will reduce the stability of the grid, making the entire system economically unfeasible and complicated to control
