[0016] Figure 2 This is a block diagram of the power control system for an energy storage power station according to an embodiment of the present invention. Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Figure 1 This is a flowchart of the power control method for an energy storage power station according to an embodiment of the present invention.

[0019] In one embodiment of the present invention, the energy storage power station may be a string energy storage power station.

[0020] like Figure 1 As shown, the power control method for an energy storage power station according to an embodiment of the present invention may include the following steps:

[0021] S1 collects key data from each energy storage converter in the energy storage power station in real time. This key data includes battery state of charge, battery health status, lower discharge safety threshold, upper charging safety threshold, and operating status.

[0022] The operating status includes discharge status and charging status.

[0023] S2, select the set of available energy storage converters based on the lower limit threshold of discharge safety, the upper limit threshold of charging safety, and the operating status of each energy storage converter.

[0024] In one embodiment of the present invention, step S2 specifically involves: when the operating state is in the discharge state, selecting energy storage converters whose battery state of charge is greater than the lower limit threshold of the discharge safety, and forming a set of usable energy storage converters; when the operating state is in the charging state, selecting energy storage converters whose battery state of charge is less than the upper limit threshold of the charging safety, and forming a set of usable energy storage converters.

[0025] Among them, the lower limit threshold for discharge safety and the upper limit threshold for charging safety can be set according to the actual situation. For example, the lower limit threshold for discharge safety is 20% and the upper limit threshold for charging safety is 90%.

[0026] S3. Based on the battery state of charge and battery health status of each energy storage converter in the available energy storage converter set, calculate the corresponding weight base quantity for power allocation of the corresponding energy storage converter, and normalize the weight base quantity of each energy storage converter to obtain the power allocation weight of each energy storage converter.

[0027] Specifically, for the i-th energy storage converter in the set of available energy storage converters, the weighted base quantity W_i of the i-th energy storage converter participating in power distribution is calculated. This weighted base quantity W_i is coupled with both the battery's state of charge and battery state of health, and can be calculated using the following formula:

[0028] During discharge, W_i = (SOC_i - SOC_min) × SOH_i;

[0029] During charging, W_i = (SOC_max - SOC_i) × SOH_i,

[0030] Where SOC_i represents the battery state of charge of the i-th energy storage converter, SOC_min represents the lower limit threshold for discharge safety, SOC_max represents the upper limit threshold for charging safety, and SOH_i represents the battery health state of the i-th energy storage converter.

[0031] Furthermore, by normalizing all the basic weights, we obtain the power allocation weight K_i of the i-th energy storage converter, i.e.

[0032] K_i = W_i / Σ(W_j),

[0033] Where W_j represents the set of available energy storage converters.

[0034] S4, allocate power to the corresponding energy storage converter according to the power allocation weight of each energy storage converter.

[0035] Specifically, the allocated power P_i of the i-th energy storage converter can be calculated using the following formula, i.e.

[0036] P_i = K_i × P_total,

[0037] Where P_total represents the total power of the system.

[0038] Therefore, by prioritizing battery state of charge, a battery health status factor is introduced to assess battery health, achieving power allocation accuracy of ±0.02kW. Furthermore, by strategically assigning more workload to batteries with healthier states, the aging rate of batteries with low health status is effectively slowed down, promoting a more consistent aging process across all batteries. This extends the overall cycle life of the battery pack by more than 20%. In addition, this mechanism automatically tilts the load towards more robust battery cells, reducing the risk of failures caused by battery overload and improving the stability and reliability of the system during long-term operation.

[0039] In one embodiment of the present invention, the power control method for an energy storage power station further includes: S5, during the discharge / charge process, acquiring abnormal state information of each energy storage converter in the set of available energy storage converters, and adopting a corresponding fault tolerance and dynamic residual compensation mechanism based on the abnormal state information. The abnormal state information includes: fault state, off-grid state, and power-limited state.

[0040] Among them, the abnormal status information of each energy storage converter in the available energy storage converter set can be read in real time through the MODBUS TCP protocol.

[0041] Specifically, in one embodiment of the present invention, step S5 specifically includes:

[0042] S51, if the abnormal status information is a fault status or a non-grid connected status, the energy storage converter that is in a fault status or a non-grid connected status will be removed, and the power will be redistributed to the remaining energy storage converters.

[0043] The method for redistributing power can be referred to in the above embodiments, and will not be described in detail here to avoid redundancy.

[0044] S52, if the abnormal state information is a power-limited state, then after allocating the maximum allowable power to the power-limited energy storage converter, calculate the power residual, and perform secondary power allocation on the energy storage converters other than the power-limited energy storage converters in the available energy storage converter set based on the power residual.

[0045] Specifically, for energy storage converters with power limitations, their limited power is allocated first, meaning the maximum allowable power is assigned to these converters. Then, the difference between the total system demand and the actual total allocation is calculated, i.e., the power residual. If the power residual is not zero, it is proportionally weighted and redistributed to the remaining unlimited available energy storage converters to ensure that the total power demand is met at 100%.

[0046] Therefore, by reducing the overcharge and over-discharge failure rate, the system's safe operating time is increased, the total power demand satisfaction rate under fault scenarios is improved, and the system reliability is enhanced, thus extending the system's safe operating time.

[0047] In one embodiment of the present invention, the power control method for an energy storage power station further includes: S6, when under low load conditions, periodically acquiring the battery health status and current cumulative operating time of each energy storage converter in the set of available energy storage converters, wherein, in each cycle, a target energy storage converter is selected from the set of available energy storage converters based on the battery health status or current cumulative operating time of each energy storage converter in the set of available energy storage converters, and the target energy storage converter is controlled to be in a working state, and the energy storage converters other than the target energy storage converter in the set of available energy storage converters are controlled to be in a dormant state.

[0048] Specifically, when the total power demand of the system is lower than the preset low-load threshold, the system is determined to be in a low-load condition. The low-load threshold can be calibrated according to actual conditions and is set to be below 10% of the rated power.

[0049] Specifically, by systematically controlling some energy storage modules to enter a dormant state, the total system load is concentrated on a few activated modules, ensuring that these activated modules operate within their high-efficiency range. Simultaneously, according to a preset rotation strategy, within each cycle, a target energy storage converter is selected from the available energy storage converter set based on the battery health status or current cumulative operating time of each converter (e.g., shortest cumulative operating time or highest battery health). This target converter is then kept active, while other energy storage converters in the available set are kept dormant. This periodic switching between active and dormant module combinations achieves a balance in the working life and aging degree of each module. Thus, through a strategy combining load concentration and loss balancing, a dynamic balance of the workload of all energy storage units is achieved, ensuring that the operating modules are always at the optimal efficiency point of the energy storage converter / battery cluster, improving system operating efficiency, reducing maintenance costs, and effectively extending the overall lifespan of the entire energy storage power station.

[0050] In one embodiment of the present invention, the battery state of charge (SOC) difference can be periodically monitored (e.g., once per minute). When a threshold is exceeded, the weights are adjusted so that energy storage converters with high SOC undertake more charging and discharging tasks, guiding the SOC towards equilibrium through dynamic prioritization. Specifically, the system no longer uses the allocation weights from the previous cycle, but recalculates the power allocation ratio of each energy storage converter based on the latest SOC, battery health, and safe operating boundaries. This recalculation process prioritizes assigning higher discharge weights to units with high SOC or higher charging weights to units with low SOC, thereby actively guiding the flow of electricity towards equilibrium within the current control cycle, as detailed in the above embodiment. Thus, through a closed-loop mechanism of "cycle detection - difference judgment - weight reconstruction - power redistribution," the system can continuously suppress the cumulative deviation of battery SOC between batteries during long-term operation, avoiding the electricity imbalance problem caused by static allocation strategies, and ensuring that the entire energy storage cluster is always in a highly efficient, safe, and balanced operating state.

[0051] In summary, the power control method for a basic energy storage power station according to embodiments of the present invention collects key data of each energy storage converter in the energy storage power station in real time. This key data includes battery state of charge (SOC), battery health status, lower discharge safety threshold, upper charge safety threshold, and operating status. Based on the lower discharge safety threshold, upper charge safety threshold, and operating status of each energy storage converter, a set of usable energy storage converters is selected. Based on the SOC and battery health status of each energy storage converter in the set of usable converters, the corresponding weight base quantity for power allocation is calculated, and the weight base quantity of each energy storage converter is normalized to obtain the power allocation weight of each energy storage converter. Power allocation is then performed on the corresponding energy storage converters according to their power allocation weights. Therefore, by allocating power to the energy storage power station based on battery SOC and battery health status, the accuracy of power allocation for the energy storage power station is greatly improved.

In one embodiment of the present invention, the screening module 200 is specifically used to: when the operating state is in the discharge state, screen out energy storage converters whose battery state of charge is greater than the lower limit threshold of the discharge safety threshold, and form a set of usable energy storage converters; when the operating state is in the charging state, screen out energy storage converters whose battery state of charge is less than the upper limit threshold of the charging safety threshold, and form a set of usable energy storage converters.

The abnormal state information includes: fault state, grid disconnection state, and power-limited state.

[0055] In one embodiment of the present invention, the acquisition module is specifically used to: if the abnormal status information is a fault state or a non-grid-connected state, then remove the energy storage converters that are in a fault state or a non-grid-connected state, and reallocate the power to the remaining energy storage converters; if the abnormal status information is a power-limited state, then after allocating the maximum allowable power to the power-limited energy storage converters, calculate the power residual, and perform secondary power allocation on the energy storage converters other than the power-limited energy storage converters in the set of available energy storage converters based on the power residual.
