Description

Technical Field

[0001] This application belongs to the field of power supply technology, and in particular relates to a method, apparatus, equipment, storage medium and product for configuring the capacity of a power supply system. Background Technology

[0002] Traditional power supply solutions for island base stations typically use the average annual effective duration of photovoltaic (PV) power as a single parameter to calculate the required PV power configuration. This method results in a relatively fixed PV system configuration, which cannot adapt to the significant fluctuations in solar resources across different months in island regions. During months with weaker sunlight, the PV system's power generation may not meet the base station's load demands, necessitating frequent startup of diesel generators as backup power. This leads to high fuel consumption and poor system economics. Summary of the Invention

Numerous islands lacking mains power, flights, and residents are surrounded by business areas focused on fishing, shipping routes, and sea fishing. The demand for voice calls and data from fishermen, vessels, and sea fishing tourists is extremely high. For these island scenarios, telecommunications operators are constructing low-carbon base station power supply systems using a combination of photovoltaic systems, energy storage batteries, and stationary diesel generators. Currently, the power supply guarantee scheme for low-carbon base stations on islands is as follows: photovoltaic systems are the primary source of power for daily use of base station equipment; energy storage batteries are used as backup to ensure equipment operation when photovoltaic power is insufficient; and stationary diesel generators are used in emergencies to provide power when battery capacity is low.

The PV system configuration calculated using this method is relatively fixed and cannot adapt to the significant fluctuations in actual solar resources across different months in island regions. In months with weaker sunlight, the PV system's power generation may not meet the base station's load demands, necessitating frequent startup of diesel generators as backup power, resulting in high fuel consumption and poor system economics.

Battery capacity investment cost Diesel generator input cost Then, the lifecycles of photovoltaics, batteries, and generators are combined, along with the evaluation proportions from different dimensions. Calculate the total cost of this configuration scheme using the following formula: ,in, , This indicates the pre-set purchase cost of the diesel generator.

[0061] In this implementation, the evaluation weighting of different dimensions can be adjusted according to needs. For example, if the focus is on fuel consumption under different photovoltaic-storage configurations, then... The percentage is 50%; the generator configuration is basically the same under different photovoltaic-storage schemes, so... It is 10%; They are 20% respectively.

[0062] Optionally, after obtaining the total cost of all configuration schemes, the total costs of all configuration schemes are compared, and the configuration scheme with the lowest total cost is selected as the target configuration scheme for the power supply system of the target base station. If there are multiple configuration schemes with the same and lowest total cost, the evaluation weight of different dimensions can be adjusted, for example, by increasing... Based on the adjusted evaluation proportion, the total cost of each scheme is recalculated to obtain the final and unique target configuration scheme.

[0063] In one feasible implementation, step 310 may further include steps C11-C13: Step C11: For each month, calculate the number of battery protection days for cloudy and rainy days based on the configuration scheme, the power utilization efficiency of the power supply system, the planned power of the equipment in the power supply system, and the effective duration of photovoltaic power generation during cloudy and rainy days in that month.

[0064] Step C12: For each month, calculate the number of sunny day battery guarantee days for that month based on the configuration scheme, the power utilization efficiency of the power supply system, the planned power of the equipment in the power supply system, and the effective duration of solar power in the sunny month.

[0065] Step C13: For each month, determine the generator operating fuel consumption for that month based on the number of rainy days, the number of sunny days, and the battery storage capacity of the power supply system in the configuration scheme.

[0066] The battery guarantee days for cloudy / rainy days refer to the maximum number of days that the energy storage battery can make up for the shortfall in photovoltaic power generation and ensure continuous power supply to the base station under cloudy / rainy conditions; the battery guarantee days for sunny days refer to the maximum number of days that the energy storage battery can make up for the shortfall in photovoltaic power generation and ensure continuous power supply to the base station under sunny conditions.

[0067] To calculate the number of battery-protected days for cloudy / rainy days in each month when the power supply system uses the same configuration scheme throughout the year, the following method can be used: For each month Based on the photovoltaic (PV) configuration power, power utilization efficiency, planned equipment power, and the effective PV duration during cloudy and rainy days in the configuration plan, the difference between the base station's power demand and PV power generation under cloudy and rainy day conditions is first calculated. Then, the number of battery protection days for cloudy and rainy days is determined according to whether the difference exceeds a preset value. If the difference is less than or equal to the preset value, it means that PV can meet the demand, and the battery protection days are set to the preset number of days. If the difference is greater than the preset value, the maximum number of days the battery can make up for the shortfall is calculated based on the battery storage capacity, power supply output voltage, and charge / discharge efficiency, thus obtaining the number of battery protection days for cloudy and rainy days.

[0068] To calculate the number of sunny days the battery can guarantee for each month when the power supply system uses the same configuration scheme throughout the year, the following method can be used: For each month Based on the photovoltaic configuration power, power utilization efficiency, planned equipment power, and the effective photovoltaic duration on sunny days in the month, the difference between the base station's power demand and photovoltaic power generation under sunny conditions is first calculated. Then, the number of battery guarantee days for sunny days is determined according to whether the difference exceeds a preset value. If the difference is less than or equal to the preset value, it means that photovoltaic power can meet the demand, and the battery guarantee days are set to the preset number of days. If the difference is greater than the preset value, the maximum number of days the battery can make up for the shortfall is calculated based on the battery storage capacity, power supply output voltage, and charge / discharge efficiency, thus obtaining the number of battery guarantee days for sunny days.

[0069] For each month's configuration scheme, after obtaining the number of days the battery can be guaranteed on sunny days and rainy days for each month when the power supply system adopts this configuration scheme throughout the year, the generator operating fuel consumption for each month can be further calculated: battery charging current I. 电池 In reality, it is determined by two factors, firstly the battery charging current I. 电池 I is equal to the product of battery capacity and battery charging rate C. 电池理论 Secondly, the battery charging current of base station I 电池 It is also equal to the maximum output power of the power supply (W). 电源 The remaining portion of I supplied to the load 电池最大 Therefore, the power supply rectification efficiency μ and the generator's hourly fuel consumption L can be used as a basis. 小时 Based on parameters such as these, the corresponding generator fuel consumption for each month is determined. The specific calculation formula is as follows: , , , .

[0070] In this embodiment, by separately calculating the number of battery backup days under cloudy and sunny conditions, and combining the battery energy storage capacity to finely calculate the generator's operating fuel consumption, the actual backup power supply capacity of the battery under different lighting scenarios is fully considered, which significantly improves the accuracy and rationality of the generator's operating fuel consumption calculation, and provides a more reliable quantitative basis for subsequent power supply cost assessment and configuration scheme selection.

[0071] In one feasible implementation, C11 may further include steps D11-D13: Step D11: Calculate the difference in electricity consumption during cloudy and rainy days in the month based on the photovoltaic configuration power that meets the power supply requirements in the configuration scheme, the power utilization efficiency of the power supply system, the planned power of the equipment in the power supply system, and the effective duration of photovoltaic power during cloudy and rainy days in the month.

[0072] Step D12: If the difference in battery power on cloudy / rainy days is less than or equal to a preset value, determine the number of battery protection days for cloudy / rainy days in the month as the preset number of days.

[0073] Step D13: If the difference in power consumption on cloudy / rainy days is greater than a preset value, determine the number of days the battery will be guaranteed for cloudy / rainy days in the month based on the difference in power consumption on cloudy / rainy days, the battery storage capacity of the power supply system in the configuration scheme, the power output voltage of the power supply system, and the battery charging / discharging efficiency of the power supply system.

[0074] The power difference on cloudy / rainy days refers to the difference between the monthly power demand of the base station and the monthly power generation of the photovoltaic system under cloudy / rainy weather conditions, which is used to measure the degree of photovoltaic power supply gap; the preset value is a pre-set power difference threshold used to determine whether the photovoltaic power supply can meet the basic power demand of the base station. In this embodiment, the preset value is 0; the preset number of days is a pre-set battery guarantee number of days. When the photovoltaic power supply can cover the base station's demand, it means that the battery can achieve full-month power supply guarantee without discharging. In this embodiment, the preset number of days is 0.

[0075] In some embodiments, for each month's configuration scheme, the number of battery-protected days for cloudy / rainy days in each month can be calculated as follows, assuming the power supply system uses this configuration scheme throughout the year: For each month According to the photovoltaic configuration power that meets the power supply requirements in this configuration scheme Power Usage Effectiveness (PUE) of the power supply system, planned power capacity (W) of the power supply system equipment, and monthly power consumption. Effective duration of solar power on cloudy and rainy days Calculate the month Electricity difference on rainy days , .

[0076] For each month's configuration plan, after obtaining the number of battery backup days for cloudy and rainy days in each month when the power supply system adopts this configuration plan throughout the year, the number of battery backup days for cloudy and rainy days in each month can be further calculated. A positive number indicates that the photovoltaic system's output power is insufficient, requiring the battery to replenish its discharge; for example... A non-positive number indicates that the photovoltaic system is outputting sufficient power and the battery does not require additional discharge. The specific calculation formula is as follows: , Indicates month Battery lifespan during rainy days.

[0077] Optionally, for each month's configuration scheme, the number of sunny days the battery can guarantee for each month can also be calculated using the above method when the power supply system adopts this configuration scheme throughout the year. The specific calculation method is as follows: ; , Indicates month The number of days the battery can guarantee operation in sunny weather.

[0078] In this embodiment, the difference in battery power on cloudy and rainy days is used as the criterion to accurately calculate the number of battery protection days on cloudy and rainy days according to different scenarios. This effectively improves the accuracy and scenario adaptability of the calculation of the number of battery protection days on cloudy and rainy days, and provides reliable basic data support for the subsequent evaluation of generator operating fuel consumption and configuration scheme economy.

[0079] This embodiment determines the generator operating fuel consumption for each month based on the configuration scheme, the effective photovoltaic duration on cloudy / rainy days for each month, and the effective photovoltaic duration on sunny days for each month. For each month, the input cost for that month is determined based on the generator operating fuel consumption, the photovoltaic power configuration that meets the power supply requirements in the configuration scheme, the battery storage capacity of the power supply system in the configuration scheme, and the energy price. The total cost of the configuration scheme is determined by calculating the input cost for each month, the photovoltaic lifecycle, the battery lifecycle, and the generator lifecycle. By accurately calculating the generator operating fuel consumption for each month and then calculating the monthly input cost, the total lifecycle cost of the configuration scheme is finally obtained. This achieves a refined and quantitative assessment of power supply costs and allows for the selection of the lowest-cost and most suitable power supply system configuration for the target base station, improving the economy and rationality of the power supply system configuration.
