Description

Technical Field

[0001] The present invention belongs to the technical field of microgrid energy storage system optimization scheduling, and in particular relates to an adaptive charging and discharging optimization scheduling method and platform for microgrid energy storage. Background Art

[0002] Currently, charging and discharging scheduling technologies for microgrid energy storage systems suffer from numerous shortcomings. For example, existing technologies often employ fixed scheduling strategies or scheduling methods based on simple load forecasting. These methods often fail to adjust the charging and discharging strategies of energy storage devices in a timely manner when faced with large fluctuations in load demand and unstable renewable energy generation. This can lead to delayed system response, overcharging or over-discharging of energy storage devices, and even impact the device's service life and the operational stability of the microgrid. Furthermore, existing technologies often fail to fully consider multidimensional factors such as the health status, charge and discharge efficiency, state of charge, and maximum power of energy storage devices. This results in a lack of flexibility in scheduling schemes and an inability to optimally allocate energy storage devices under varying health states and operating conditions. In particular, in environments with high-frequency load fluctuations and significant power fluctuations in renewable energy sources (such as solar and wind power), traditional scheduling methods struggle to balance system stability, energy efficiency, and device lifespan. Therefore, an adaptive charging and discharging optimization scheduling method that can dynamically adapt to load demand and renewable energy fluctuations is urgently needed.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1: Figure 1, which is a flow chart of the first embodiment of the adaptive charging and discharging optimization scheduling method for microgrid energy storage of the present invention, and proposes the first embodiment of the adaptive charging and discharging optimization scheduling method for microgrid energy storage of the present invention.

[0046] In a first embodiment, the adaptive charging and discharging optimization scheduling method for microgrid energy storage includes:

[0047] Step S10: Acquire microgrid energy storage operation information from the background resource management process within a preset time period T, including health status data, current charge and discharge efficiency data, current power percentage data, maximum rated power data, real-time load demand of the microgrid, load demand change, and microgrid renewable energy generation power, and construct a microgrid state matrix E and a microgrid load demand matrix G based on the microgrid energy storage operation information;

[0048] It should be noted that, in step S10, the microgrid state matrix E is expressed as:

[0049]

[0050] Among them, SOH i is the health status data of the i-th energy storage device, Eff i is the current charge and discharge efficiency data of the i-th energy storage device, SOC i is the current power percentage data of the i-th energy storage device, P max, is the maximum rated power data of the i-th energy storage device, and N is the total number of microgrid energy storage devices;

[0051] The microgrid load demand matrix G is expressed as:

[0052]

[0053] in, is the real-time load demand of the microgrid of the i-th energy storage device, is the change in load demand of the i-th energy storage device, is the microgrid renewable energy generation power of the i-th energy storage device.

[0054] It can be understood that the health status data reflects the service life and health level of the energy storage device, and the numerical range is usually between 0 and 1. The closer to 1, the healthier the device; the current charge and discharge efficiency data represents the current charge and discharge conversion efficiency of the energy storage device. The higher the value, the smaller the energy conversion loss; the current power percentage data shows the current battery power of the device as a percentage of its maximum capacity, and the numerical range is usually 0% to 100%; the maximum rated power data represents the maximum power that the device can withstand when charging or discharging, in kilowatts (kW); the real-time load demand of the microgrid represents the current total power demand of the microgrid; the change in load demand reflects the changing trend of load demand and is used to measure load fluctuations; the microgrid renewable energy power generation power represents the real-time power generation from renewable energy sources such as solar energy and wind energy in the system.

[0055] Step S20: First, the microgrid energy storage operation information of n microgrid energy storage devices is stored in JSON data format to obtain a microgrid energy storage device set, and the microgrid energy storage device set is initialized and arranged to obtain ring geometric structure data, and then the device fitness F of the i-th energy storage device is dynamically calculated according to the microgrid state matrix E and the microgrid load demand matrix G. i , and determine the distribution radius R of the i-th energy storage device in the ring geometry data i ;

[0056] It should be noted that in step S20, the device fitness F of the i-th energy storage device is dynamically calculated based on the microgrid state matrix E and the microgrid load demand matrix G. i Steps, using the formula:

[0057]

[0058] Among them, w1, w2, w3, and w4 are the weight factors of each factor, ||G|| is the modulus of the matrix G, ||E|| is the modulus of the matrix E, and τ is the global adjustment factor of the device fitness.

[0059] In step S20, the distribution radius R i The calculation formula is:

[0060]

[0061] Among them, R max is the preset outer ring radius threshold, which is used to represent the device location with the lowest task priority; R min is the preset inner ring radius threshold, which is used to represent the device position with the highest task priority; max(F) is the maximum fitness of all devices, which is used for normalization.

[0062] It should be understood that the device fitness reflects the comprehensive performance of the energy storage device under the current system state. The higher the fitness of the device, the smaller the distribution radius R. i The smaller the device state, the higher the priority for participating in charge and discharge scheduling. By combining the device status and the system load demand matrix and introducing a global adjustment factor for device fitness, adaptive adjustment of device scheduling can be achieved, dynamically responding to system load fluctuations and changes in renewable energy.

[0063] For example, if Figure 2 As shown, the device operation information is stored in JSON data format, which is convenient for transmission and processing within the system. Based on the JSON data, the system will initialize the device collection.

[0064] Fitness calculation formula: Assume w1=w2=w a =w4=0.25,τ=1, calculate the fitness F of each device i :device 1: F1 = (0.225 + 0.2125 + 0.15 + 0.15) = 0.7375; Device 2: F2 = (0.2 + 0.225 + 0.1 + 0.05) = 0.575; Device 3: F3=(0.175+0.2+0.05+0.0833)=0.5083.

[0065] Distribution radius calculation formula: Assume R max =10m, R min =2 m, max(F) = 0.7375, calculate the distribution radius R of each device i , device 1: Device 2: Device 3:

[0066] like Figure 3 As shown, the calculated fitness and distribution radius are also stored in JSON format.

[0067] Step S30: Real-time collection of renewable energy power generation fluctuation ΔP renew , according to the fluctuation of renewable energy power generation power ΔP renew Dynamically adjust the distribution radius of the i-th energy storage device in the ring geometry data to obtain the optimized distribution radius R;

[0068] It should be noted that, in step S30, the calculation formula for optimizing the distribution radius R is:

[0069]

[0070] Where k is the adjustment coefficient for the impact of fluctuations on equipment distribution.

[0071] It should be understood that the optimized distribution radius R, based on the original fitness, is dynamically adjusted according to the fluctuations in renewable energy. The greater the fluctuation, the more significant the adjustment in the distribution radius, enabling the system to more flexibly respond to instabilities in load and power generation. By introducing the fluctuation adjustment factor k, the system can achieve flexible control under different environmental conditions.

[0072] For example, device 1: R1 = 2m, device 2: R2 = 3.77m, device 3: R3 = 4.48m, the power fluctuation of renewable energy generation ΔP renew =4kW, Maximum rated power of the equipment P max, :Device 1: 5kW, Device 2: 10kW, Device 3: 15kW, Fluctuation adjustment coefficient k = 1; Calculate the optimized distribution radius R,

[0073] Before the adjustment, device 1 was distributed in the innermost layer (2 meters) and had the highest scheduling priority. Devices 2 and 3 were distributed in the outer layer and had lower scheduling priorities. After the adjustment (due to increased fluctuations), the distribution radius of all devices increased, indicating the system's response to renewable energy fluctuations. Although the priority of device 1 was still higher, the gap between devices narrowed, indicating that the system needed more devices to jointly respond to load changes to ensure system stability.

[0074] Step S40: performing preliminary adaptive allocation of charging and discharging tasks for each energy storage device based on the optimized distribution radius R;

[0075] It should be noted that in step S40, the step of performing preliminary adaptive allocation of the charging and discharging tasks of each energy storage device based on the optimized distribution radius R specifically includes:

[0076] Step S401: When the renewable energy generation power of the i-th energy storage device Exceeding real-time load demand Trigger the charging mode task instruction and calculate the charging power P charge,i ;

[0077] Step S402: When the renewable energy generation power of the i-th energy storage device Do not exceed real-time load demand Trigger the discharge mode task instruction and calculate the discharge power P discharge,i .

[0078] Charging power Pcharge,i The calculation formula is Discharge power P discharge,i The calculation formula is Among them, η charge is the preset charging efficiency coefficient, η discharge is the preset discharge efficiency coefficient.

[0079] It should be understood that the optimized distribution radius R is a key parameter for preliminary adaptive allocation. The closer the device is to the load center, the higher its scheduling priority, and the system will prioritize these devices for charging and discharging. The charging and discharging power is proportional to the inverse of the distribution radius. This design ensures that devices with high adaptability (small distribution radius) are prioritized in system scheduling, while preventing devices far from the load center from being frequently scheduled, reducing energy transmission losses.

[0080] For example, if Figure 4 As shown, the initial and optimized distribution radii (filled with backslashes) show significant differences for devices 1 through 5. Device 1's distribution radius increases the most, from 2m to 10.5m, indicating a lower priority for this device in system scheduling, reducing its frequency of participation. The optimized distribution radii for devices 3, 4, and 5 show less change, indicating that the system scheduling algorithm considers these devices to be in better condition and suitable for frequent scheduling under current load and fluctuation conditions.

[0081] By adjusting the distribution radius, the system effectively prioritizes devices, reducing the frequency of participation for devices in poor condition or with poor load adaptability, thereby improving overall system efficiency. The optimized distribution radius accounts for real-time load and renewable energy fluctuations, enabling the system to maintain optimal scheduling strategies under varying operating conditions, improving system stability and reliability.

[0082] Step S50: continuously and adaptively allocate the charging and discharging tasks of each energy storage device in combination with the rolling optimization algorithm.

[0083] It should be noted that the rolling optimization algorithm introduced in step S50 is a time-series-based dynamic adjustment method that optimizes the charging and discharging tasks of energy storage devices in real time by regularly updating system status and forecast information. This method can continuously adjust the energy storage device scheduling strategy as load demand and renewable energy sources fluctuate, thereby improving system flexibility and reliability.
