The present invention discloses a method and system for participating in grid frequency regulation within full range of charging and discharging of energy storage, comprising: collecting grid operation power and frequency data, and constructing a full-range droop coefficient; setting constraints of upper and lower limits of a frequency deadband, obtaining an actual output power command value based on the constraint function constructed from a theoretical power command value and a rated charging and generating power value, and controlling operation of the grid; and setting a hysteresis interval on the power command of an energy storage system, wherein when the demand of the grid exceeds the upper threshold, the energy storage system switches from the charging mode to the discharging mode; and when the demand of the grid falls below the lower threshold, the energy storage system switches from the discharging mode to the charging mode.

A fault managed power (FMP) transmitter for use in an electrical power system, having a power source port configured to be connected to a first electrical power source of the plurality of electrical power sources and an power bus port configured to be electrically connected to the common electrical bus. There is at least one switch between the power source port and the power bus port and processing circuitry configured to control the at least one switch to receive power from the first electrical power source and to transmit FMP output pulses via the power bus port over the common electrical bus to the FMP receiver. The processing circuitry is configured to receive an external timing trigger to enable the processing circuitry to synchronize the transmission of the FMP output pulses with the transmission of FMP output pulses from each of the at least one other FMP transmitter.
