This part of IEC 61557 specifies requirements for insulation monitoring devices (IMD), which permanently monitor the insulation resistance RF to earth of unearthed a.c. IT systems, of a.c. IT systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as of unearthed d.c. IT systems with voltages up to 1 500 V d.c. independent from the method of measuring. Insulation monitoring detects insulation resistance by monitoring the leakage current from high-voltage terminals to protective earth/chassis ground. Since currents above 10 mA can be fatal, insulation monitoring systems must provide warnings upon the detection of faults in the insulation. [pdf]

In practical application, through the anti-reverse current meter + CT transformer installed on the bus on the inlet side of the house, to obtain the real-time power of the line, the size and direction of the current, when detecting the current flow to the grid (reverse current), then the anti-reverse current meter will transmit the reverse current power data to the inverter through the RS485 communication, the inverter will receive the instruction and respond in seconds to reduce the output power of the inverter, so that the current flow to the grid from the PV power plant will be reduced to the power grid.

A certain 800MW/1.6GWh container energy storage power station in Gansu Province participates in the "deep peak shaving" service of the Northwest Power Grid: during low load periods of the power grid (such as 2-6 am), it absorbs new energy waste power (maximum charging power of 800MW) to avoid wind and solar waste; During peak load periods (such as 18-22 pm), release electricity (maximum discharge power of 800MW) to alleviate the power supply pressure on the grid.
