Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] See figure 1 , the embodiment of the present invention provides a hybrid energy storage system 10 , including: a first energy storage system 100 , a second energy storage system 200 and a control system 300 .

[0021] The first energy storage system 100 has relatively large capacity but general flexibility. The flexibility generally means that the power adjustment range of the energy storage system is limited, and the efficiency varies significantly with power, that is, the ratio of efficiency change / power change is relatively large. See figure 2 , the efficiency of the first energy stor...

Abstract

The invention relates to a hybrid energy storage system. The hybrid energy storage system comprises a first energy storage system, a second energy storage system and a control system, wherein the capacity of the first energy storage system is larger than the capacity of the second energy storage system, the flexibility of the second energy storage system is larger than the flexibility of the firstenergy storage system, and the control system is used for acquiring information of the first energy storage system and the second energy storage system and controlling powers of the first energy storage system and the second energy storage system according to the information. The invention simultaneously proposes a power control method of the hybrid energy storage system and a storage medium.

Description

technical field [0001] The invention relates to a hybrid energy storage system, a power control method thereof, and a storage medium, belonging to the field of electric power. Background technique [0002] Wind energy resources have the characteristics of randomness, intermittency, and low prediction accuracy. These characteristics make it difficult to effectively control and dispatch the output of wind power plants. Determinism limits the widespread application of wind power, and wind curtailment often occurs. [0003] The energy storage system can store the power during the low load period and release it during the peak load period, and the joint application with wind power can smooth the fluctuation of wind power output. However, traditional energy storage often has certain shortcomings, especially when dealing with rapidly changing scenarios of different wind farms. Contents of the invention [0004] Based on this, it is necessary to provide a hybrid energy storage s...
