[0044] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0045] The following describes the scheduling method, device, electronic device, and storage medium of the energy storage system according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0046] Figure 1 A flowchart of a scheduling method for an energy storage system provided in an embodiment of the present disclosure is provided.

[0047] like Figure 1 As shown, the method comprises the following steps:

[0048] Step 101: Acquire an active power instruction and determine a control target of the active power instruction; wherein the control target includes a station or a system; and the station includes at least two systems.

[0049] Active power commands are control instructions for power transmission and distribution within a power system or power station. They serve as the starting point for the entire power regulation control process. Obtaining these commands enables subsequent targeted control operations. There are two types of control targets: station and system. A system, in this context, refers to a functional, interconnected component of a power system capable of independently completing specific power transmission, conversion, or distribution tasks. A station, on the other hand, is a more comprehensive concept encompassing at least two systems that work together to achieve its functions within the power network, such as energy collection, conversion, and distribution. After obtaining an active power command, clarifying whether the command applies to the entire station or a specific system within it ensures more accurate and efficient power control, avoids control confusion or ineffective regulation caused by unclear control targets, and ensures stable and reliable operation of the power system or power station.

[0050] Step 102: In response to the active power instruction, perform active power regulation on the control target.

[0051] When the control target is a power station, since the station contains at least two systems, the regulation process needs to coordinate the power distribution between the systems. For example, by adjusting the transformer ratio, generator output, or operating parameters of the power conversion device within the station, the overall active power output of the station meets the command requirements. If the control target is a specific system, the focus is on the power regulation elements within the system. For example, by controlling the trigger angle of the converter, adjusting the charge and discharge power of the energy storage device, or changing the load on / off status, the system active power can be precisely regulated. In this process, the actual active power value of the control target is collected in real time by sensors and compared with the command target value. The closed-loop control algorithm generates a regulation signal and drives the actuator to operate to ensure the dynamic response speed and steady-state accuracy of the regulation process, avoid the impact of power fluctuations on the stability of the power system, and ultimately ensure that the active power output of the control target is consistent with the command requirements, ensuring the safe and economical operation of the power system.

[0052] In some embodiments, in response to the active power instruction, performing joint active power regulation of the photovoltaic power station monitoring system and the energy storage monitoring system further includes:

[0053] When it is determined that the control target of the active power instruction is the station, in response to the active power instruction, the photovoltaic power station monitoring system and the energy storage monitoring system are jointly regulated by the station coordination module.

[0054] The site coordination module is a control hub deployed at the site level. Its core function is to coordinate the power output of each subsystem within the site based on the target value of the active power command to achieve overall power balance. Specifically, the module first receives the active power command from the upper-level system and simultaneously collects real-time power generation feedback from the PV plant monitoring system (such as the current output of the PV array, light intensity, temperature, and other operating parameters) and energy storage device status feedback from the energy storage monitoring system (including state of charge (SOC), charge and discharge power limits, and available capacity). Based on this data, the site coordination module calculates the active power regulation required of the PV plant and the energy storage system respectively using a preset power allocation strategy (such as prioritizing PV output and having the energy storage system supplement or absorb any remaining power shortfall). The module then sends regulation commands (such as adjusting the output power of the PV inverter and changing the maximum power point tracking (MPPT) parameters) to the PV plant monitoring system and simultaneously sends charge and discharge control signals (such as setting the active power reference value of the energy storage converter (PCS) and switching the charge and discharge modes) to the energy storage monitoring system, promoting coordinated operation between the two. During this process, the station coordination module continuously monitors the deviation between the actual power output of the two systems and the command target value. Using a closed-loop control mechanism, it fine-tunes the adjustment parameters in real time. For example, if the PV output suddenly drops due to cloud cover, the energy storage system's discharge power is rapidly increased to compensate for the power shortfall, ensuring that the station's overall active power output strictly tracks the command requirements. This combined adjustment method fully leverages the renewable energy generation capacity of the PV system and the power buffering function of the energy storage system, effectively smoothing station power fluctuations, improving the quality of grid-connected power, and ensuring that station operations comply with grid dispatch requirements.

[0055] In some embodiments, in response to the active power instruction, performing joint active power regulation of the photovoltaic power station monitoring system and the energy storage monitoring system further includes:

[0056] When it is determined that the control target of the active power instruction is the system, in response to the active power instruction, the instruction is transmitted to the energy storage monitoring system through the integrated communication management terminal. The energy storage monitoring system coordinates and controls the energy storage system according to the instruction and performs independent active power regulation on the energy storage system.

[0057] The integrated communication management terminal has the communication and data processing capabilities to receive active power instructions from the upper system and perform pre-processing operations such as parsing and encoding on the instructions to ensure the accuracy and integrity of the instructions during transmission.

[0058] After receiving the active power command transmitted via the integrated communication management terminal, the energy storage monitoring system coordinates and controls the energy storage system according to the command requirements and performs independent active power regulation. The energy storage monitoring system collects various key data in the energy storage system in real time, such as the voltage, current, temperature, state of charge (SOC), state of health (SOH) of the energy storage battery pack, and the operating parameters of the energy storage converter (PCS). Combined with the target value of the active power command, it uses advanced control algorithms and strategies to accurately calculate the active power output currently required by the energy storage system. Subsequently, the energy storage monitoring system sends a control signal to the energy storage converter in the energy storage system to adjust its operating mode and operating parameters, such as changing the converter's trigger angle and modulation ratio, thereby controlling the energy storage system to perform charging or discharging operations and achieve precise regulation of active power.

[0059] Throughout the regulation process, the energy storage monitoring system continuously monitors the deviation between the energy storage system's actual active power output and the command target value, and adjusts the control strategy and parameters in real time through a feedback control mechanism. For example, if the energy storage system's actual discharge power falls short of the command requirement, the energy storage monitoring system promptly increases the control signal to the energy storage converter, boosting the discharge power. This ensures that the energy storage system's active power output can quickly and stably track the command, achieving precise power regulation for the system and ensuring stable operation and power balance of the power system.

[0060] In some embodiments, when determining that the control target of the active power instruction is a station, responding to the active power instruction, performing joint active power regulation on the photovoltaic power station monitoring system and the energy storage monitoring system through the station coordination module further includes:

[0061] The site coordination module dynamically allocates active power regulation tasks based on the current power generation capacity of the photovoltaic power station and the energy storage status of the energy storage system.

[0062] The current power generation capacity of a PV power station is not fixed; it is affected by a variety of factors, including light intensity, ambient temperature, and the cleanliness of the PV modules. The site coordination module collects relevant data in real time from the PV power station monitoring system, such as the real-time output voltage and current of the PV array, to calculate the current power generation capacity. It also combines weather forecast data to predict the power generation trend of the PV station over the next period of time.

[0063] The energy storage system's energy status is primarily reflected by its state of charge (SOC), which directly reflects the amount of energy currently stored. Furthermore, the system's charge and discharge power limits and state of health (SOH) are also important reference indicators. After acquiring this data, the site coordination module flexibly formulates a power regulation task allocation strategy based on actual conditions.

[0064] When the photovoltaic power station has a strong power generation capacity and the energy storage system is in a low state of charge, the site coordination module will prioritize allocating more power output tasks to the photovoltaic power station, while allowing the energy storage system to charge at a lower power. On the premise of ensuring the completion of the active power instruction requirements, it fully utilizes renewable energy and reserves electricity for subsequent possible power regulation needs. If the photovoltaic power station has insufficient power generation capacity and the energy storage system has a high state of charge, the site coordination module will increase the discharge power of the energy storage system so that it and the photovoltaic power station can jointly undertake the active power regulation task and make up for the gap in insufficient photovoltaic output.

[0065] Moreover, during the entire dynamic allocation process, the site coordination module will continuously monitor changes in the photovoltaic power station's power generation capacity and the energy storage system's energy storage status. Once an abnormal situation occurs, such as sudden cloud cover causing a sudden drop in the photovoltaic power station's power generation, or the energy storage system limiting the charging and discharging power due to excessive temperature, the site coordination module will immediately readjust the task allocation to ensure that the site's overall active power output can stably and accurately match the requirements of the active power instruction, thereby improving the stability and economy of the site's operation.

[0066] In some embodiments, when determining that the control target of the active power instruction is the system, in response to the active power instruction, transmitting the instruction to the energy storage monitoring system via the integrated communication management terminal, wherein the energy storage monitoring system coordinates and controls the energy storage system according to the instruction, and performing independent active power regulation on the energy storage system further includes:

[0067] After receiving the active power instruction of the energy storage system, the energy storage monitoring system distributes the adjustment task to multiple energy storage converter modules according to the operating status and energy storage capacity of the energy storage converter to control the balanced power output.

[0068] As the core device for AC / DC conversion in energy storage systems, the energy storage converter's operating status encompasses several key parameters, including current output voltage, current, frequency, efficiency, as well as device temperature, heat dissipation, and fault alarm information. These parameters not only reflect the converter's current functioning but also determine the upper limit of its safe and stable output power.

[0069] Energy storage capacity is primarily reflected through the state of charge (SOC) and state of health (SOH). SOC indicates the current percentage of energy stored in the energy storage system, while SOH reflects the degree of performance degradation and remaining useful life of the energy storage system. Together, these two factors determine the range of the energy storage system's ability to participate in power regulation. After comprehensively analyzing this information, the energy storage monitoring system will formulate a scientific task allocation strategy.

[0070] For energy storage converter modules that are in good operating condition and have sufficient connected energy storage capacity, relatively more adjustment tasks will be assigned; for modules with minor abnormalities or low connected energy storage capacity, the amount of tasks will be appropriately reduced to avoid damage due to overload operation, which will affect the reliability and service life of the entire energy storage system.

[0071] During the specific control process, the energy storage monitoring system sends precise control signals to each energy storage converter module to adjust its output power, operating mode, and other parameters. For example, by changing the converter's trigger pulse width and phase, it controls the magnitude and direction of its output current, ensuring that the power output difference between modules is within a reasonable range. At the same time, the energy storage monitoring system monitors the actual output power of each energy storage converter module in real time. If a power imbalance is detected, such as a module's output power being significantly higher or lower than that of other modules, the system will quickly adjust the control strategy and reallocate regulation tasks to achieve dynamic and balanced power output, ensuring efficient and stable operation of the energy storage system and accurately responding to active power command requirements.

[0072] In some embodiments, before obtaining the active power instruction and determining the control target of the active power instruction, the method further includes:

[0073] The energy storage monitoring system obtains the operating status information of the energy storage incoming line switch and the energy storage inverter boost system, and sends the status information to the monitoring system.

[0074] Before obtaining the active power instruction and determining the control target, the energy storage monitoring system must first obtain the operating status information of the energy storage incoming switch and the energy storage inverter boost system, and send it to the monitoring system. Among them, the energy storage incoming switch is a key electrical component that connects the energy storage system to the external power grid or other equipment in the station. Its operating status is directly related to whether the energy storage system can normally access the power network and the safety of power transmission. The energy storage monitoring system collects information such as the switch's opening and closing status, contact temperature, mechanical life loss, and electrical parameters (such as current and voltage) in real time through various sensors installed at the energy storage incoming switch. For example, if the switch contact temperature is too high, it may indicate poor contact or overload, posing a safety hazard; and abnormal opening and closing status will affect the power input and output of the energy storage system, resulting in an inability to participate in power regulation normally.

[0075] The energy storage inverter boost system is the core component that realizes the energy storage system's energy form conversion and voltage boost, and its operating status information is also crucial. The energy storage monitoring system monitors the energy storage inverter's output power, conversion efficiency, DC side voltage and current, AC side power quality (such as harmonic content, phase, and frequency), as well as the step-up transformer's oil temperature, winding temperature, transformation ratio, short-circuit impedance and other parameters. For example, when the inverter conversion efficiency decreases or the output power harmonics exceed the standard, it will not only affect the efficiency of the energy storage system, but may also pollute the power quality of the grid; if the step-up transformer oil temperature is too high or the winding fails, it will threaten the stable operation of the entire system.

[0076] After acquiring this detailed operating status information, the energy storage monitoring system performs preliminary data processing and analysis, then transmits this information in real time to the monitoring system via the communications network. As the hub of overall dispatch management, the monitoring system comprehensively assesses the energy storage system's operating status and determines whether it meets the requirements for participating in active power regulation. This provides a reliable basis for subsequently obtaining active power commands, determining control targets, and executing power regulation operations. This ensures that the energy storage system operates safely and stably, avoiding system failures or power regulation failures caused by equipment anomalies.
