Technical Field
[0001] The present invention belongs to the technical field of energy storage devices, and in particular relates to an energy storage device optimization scheduling method for a hybrid energy storage system. Background Art
[0002] Compared with energy storage systems that use a single energy storage device, hybrid energy storage systems have multiple advantages such as regulation reliability and stability. However, at the same time, due to the differences in the energy storage characteristics of different types of energy storage devices, how to optimize the scheduling of different types of energy storage devices in hybrid energy storage systems has become a technical problem that needs to be solved urgently.
[0003] In the existing technical solutions, the goal is often to optimize the economic optimization or the highest operating efficiency, and to construct an optimization scheduling function to optimize the scheduling of different energy storage devices in the hybrid energy storage system, so that the operating efficiency of the hybrid energy storage system is in the best state or the economic benefits are in the best state. However, through analysis, the existing technical solutions have the following technical defects:
[0004] When generating energy storage scheduling strategies, existing technical solutions ignore the differences in the number of times different energy storage devices are disconnected from the grid and the differences in the service life of different energy storage devices. Specifically, frequent off-grid control will inevitably lead to deterioration of the power quality in response to energy storage needs. At the same time, too many adjustments of energy storage devices will also have a certain degree of impact on the service life of the energy storage devices. Therefore, if the above factors are not considered, the reliability of energy storage regulation cannot be guaranteed.
[0005] In order to solve the above technical problems, the present invention provides a method for optimizing the scheduling of energy storage devices for a hybrid energy storage system. Summary of the invention
[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:
[0007] In order to solve the above technical problems, the present invention provides an energy storage device optimization scheduling method for a hybrid energy storage system, which specifically includes:
[0008] S1 performs similarity analysis of historical similar energy storage regulation requirements of the energy storage regulation instructions and different historical similar energy storage regulation requirements according to the corresponding time of the energy storage regulation instructions and weather data;
[0009] S2 obtains response deviation data of different types of energy storage devices in response to different historical similar energy storage regulation requirements, and when it is determined that there is no energy storage device whose regulation reliability meets the requirements in combination with the similarity of different historical similar energy storage regulation requirements, proceeds to the next step;
[0010] S3 uses historical regulation data to determine the response rate of load fluctuations of different types of energy storage devices, and determines the fluctuation regulation reliability of different types of energy storage devices based on the similarity of the waveforms before and after different types of energy storage devices in response to different load fluctuation depths;
[0011] S4 determines the power allocation ratio of different types of energy storage devices and the fluctuation regulation energy storage devices based on the historical cycle data, real-time energy storage parameters and fluctuation regulation reliability of different types of energy storage devices, and uses the power allocation ratio and fluctuation regulation energy storage devices to generate an energy storage scheduling strategy for the hybrid energy storage system.
[0012] The beneficial effects of the present invention are:
[0013] 1. Based on the response deviation data in response to different historical similar energy storage regulation demands and the similarity of different historical similar energy storage regulation demands, it is determined whether there is energy storage equipment whose regulation reliability meets the requirements, thereby realizing the screening of energy storage equipment whose regulation reliability does not meet the requirements from the perspective of the response deviation of historical similar energy storage regulation demands, and then realizing the determination of differentiated regulation methods for energy storage equipment, which not only ensures the reliability of energy storage regulation, but also avoids the emergence of technical problems with a greater impact on life loss caused by too much investment of energy storage equipment.
[0014] 2. Generate energy storage dispatch strategies for hybrid energy storage systems using power allocation ratios and fluctuation regulation energy storage devices. This not only takes into account the regulation of fluctuation demands of the hybrid energy storage system through fluctuation regulation energy storage devices, but also takes into account the determination of differentiated power allocation ratios due to differences in energy storage capacity and historical cycle numbers of different types of energy storage devices in the hybrid energy storage system. This ensures that energy storage devices with higher fluctuation regulation reliability, fewer cycles, and larger energy storage capacity can be allocated more regulation power.
[0015] A further technical solution is that the weather data includes humidity, temperature and wind speed at a corresponding moment of the energy storage regulation instruction.
[0016] A further technical solution is that the method for determining the historical similar energy storage regulation requirements of the energy storage regulation instructions is:
[0017] Determine the time deviation between the energy storage regulation instruction and the corresponding time of different historical energy storage regulation requirements through the corresponding time of the energy storage regulation instruction;
[0018] Determine the weather data deviations of the energy storage regulation instruction and different historical energy storage regulation requirements in different dimensions based on the weather data of the energy storage regulation instruction, and determine the comprehensive weather data deviations of the energy storage regulation instruction and different historical energy storage regulation requirements using the weather data deviations in different dimensions;
[0019] The similarity between the energy storage regulation instruction and different historical energy storage regulation requirements is determined by the time deviation and the comprehensive weather data deviation, and the similarity is used to determine the historical similar energy storage regulation requirements of the energy storage regulation instruction.
[0020] A further technical solution is to use the similarity to determine the historical similar energy storage regulation requirements of the energy storage regulation instructions, specifically including:
[0021] When the similarity of the historical energy storage regulation demand meets the requirement, the historical energy storage regulation demand is determined to be a historical similar energy storage regulation demand.
[0022] A further technical solution is that the response deviation data is determined based on the real-time energy storage parameters of the energy storage device and the deviation of the regulation requirements of the historical similar energy storage regulation requirements.
[0023] A further technical solution is that the response deviation data includes the adjustment rate deviation moment and the response rate deviation amount and the energy storage demand capacity deviation amount at different adjustment rate deviation moments.
[0024] A further technical solution is that the fluctuation regulation reliability of the energy storage device ranges from 0 to 1, wherein the greater the fluctuation regulation reliability of the energy storage device, the higher the regulation reliability of the energy storage device in response to load fluctuations.
[0025] A further technical solution is that the historical cycle data includes the historical cycle number of the energy storage device and the energy storage regulation depth at different historical cycle numbers.
[0026] A further technical solution is to generate an energy storage scheduling strategy for the hybrid energy storage system using the power allocation ratio and the fluctuation regulation energy storage device, specifically including:
[0027] When the load fluctuation at the current moment is within the preset fluctuation range, the power allocation ratio is used to determine the allocation ratio of the regulating power of different types of energy storage devices of the hybrid energy storage system;
[0028] When the load fluctuation at the current moment is not within the preset fluctuation range, the fluctuation regulation energy storage device responds to the load fluctuation of the energy storage demand, and when the load fluctuation drops to within the preset fluctuation range, the power allocation ratio is continued to be used to determine the allocation ratio of the regulation power of different types of energy storage devices of the hybrid energy storage system.
