The embodiment of the present invention discloses a method and device for controlling output of a power grid energy storage system. The method includes: receiving a target power scheduling instruction, determining the current charging state value and operation mode of the energy storage system, and setting the power of the generator set according to the operation mode. Track the deviation and send it to the generator set controller, so that: the generator set controller sets the second target output value of the generator set, controls the generator set to output power according to the second target output value, and sends the current output power of the generator set to The energy storage system controller calculates the difference between the first target output value and the current output power of the generating set, and controls the output power of the energy storage system according to the difference and the operation mode. This solution transforms the fast and repeated output adjustment requirements into the adjustment requirements with long duration in one direction and less conversion times. While meeting the target power scheduling instructions, it greatly prolongs the service life of the energy storage system and reduces operating costs.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for controlling output of a power grid energy storage system. Background technique [0002] With the development of electric power technology, electric energy has become an indispensable energy source in people's daily life. At present, the power grid power generation system mainly includes thermal power generation, hydropower generation, nuclear power generation and new energy power generation systems. In the grid power generation system, it includes a generator set for generating output and a generator set controller for controlling the generator set. In order to ensure fast and stable response to Automatic Generation Control (AGC) scheduling instructions, the grid power generation system also includes an energy storage system for coordinating the operation of the generator set and an energy storage system controller for controlling the energy stora...
