The invention provides a new energy storage system and a power adjustment method and a power distribution method thereof. The method comprises the steps that a target instruction for increasing the total active power is received in a power limiting state, if a preset quick adjustment condition is met, and the energy storage system can meet the adjustment demands of the target instruction, an energy storage system and a new energy system are controlled to increase output at the same time so that the new energy storage system can meet the target instruction to the maximum extent; then, under thecondition that the new energy system meets the new energy adjusting condition, the new energy system is controlled to increase the output, so that the output of the energy storage system is reduced under the same total active power. Namely, the system for increasing the output can be determined in time according to the current situation of the energy storage system, so that the target instructionis met as soon as possible to the maximum extent, and compared with an existing adjustment mode, the adjustment method provided by the invention has the advantages that the timeliness and accuracy ofsystem adjustment are improved; and after timely adjustment is realized, the output of the energy storage system can be transferred, and the economic effect of the system is improved.
Description
technical field [0001] The invention relates to the technical field of energy storage, in particular to a new energy storage system, a power adjustment method and a power distribution method thereof. Background technique [0002] In the renewable energy system, the energy storage system is generally combined with the power generation system, such as the combination of the energy storage system and the photovoltaic power generation system, or the combination of the energy storage system and the wind power generation system, so as to realize the power supply of the power generation system to the grid through the energy storage system. Reasonable adjustment. For example, when the power generation system generates excess electric energy, the energy storage system is used to store electric energy; when the electric energy is insufficient or unstable, the energy storage system is used for power supply or adjustment to realize the flexible application of electric energy.
