The first energy storage resource capacity information represents the energy storage capacity of the energy storage medium corresponding to the first energy storage resource attribute information set. The first energy storage resource charging and discharging power information characterizes the power of the energy storage resource corresponding to the first energy storage resource attribute information set when the energy storage resource is charged and discharged in unit time. In practice, the energy storage medium of the energy storage resource corresponding to the first energy storage resource attribute information set may be a lithium battery or a lead-acid battery. In practice, the execution body may determine the sum of the energy storage capacities of the energy storage media corresponding to the first energy storage resource attribute information set as the first energy storage resource capacity information. The execution body may determine a sum of power levels of the energy storage resources corresponding to the first energy storage resource attribute information set when the energy storage resources are charged and discharged in a unit time as the first energy storage resource charging and discharging power information.

In some optional implementations of some embodiments, the executing body determines, according to the first energy storage resource attribute information set, an energy storage resource capacity and an energy storage resource charging/discharging power of an energy storage resource corresponding to the first energy storage resource attribute information set, to obtain first energy storage resource capacity information and first energy storage resource charging/discharging power information, and may include the following steps:

and determining the sum of energy storage capacities included in each first energy storage resource attribute information in the first energy storage resource attribute information set as the first energy storage resource capacity information.

In practice, the first energy storage resource capacity information may characterize an energy storage capacity range of the energy storage resource.

As an example, the first set of energy storage resource attribute information may be [ first energy storage resource attribute information a, first energy storage resource attribute information B, first energy storage resource attribute information C ]. The first energy storage resource attribute information a includes an energy storage capacity of [200kwh 10kwh ]. Here, "200kWh" is the upper limit value of the energy storage capacity in the rated capacity range. "10kWh" is the lower limit value of the energy storage capacity in the rated capacity range. The first energy storage resource attribute information B includes an energy storage capacity of [300kwh 20kwh ]. The first energy storage resource attribute information C includes an energy storage capacity of [400kwh 30kwh ]. Thus, the first energy storage resource capacity information may be [900kwh 60kwh ].

And a second step of determining the sum of the energy storage charging and discharging power included in each first energy storage resource attribute information in the first energy storage resource attribute information set as the first energy storage resource charging and discharging power information.

In practice, the first energy storage resource charging and discharging power information may represent an energy storage charging and discharging power range of the energy storage resource.

As an example, the first set of energy storage resource attribute information may be [ first energy storage resource attribute information a, first energy storage resource attribute information B, first energy storage resource attribute information C ]. The energy storage charging and discharging power included in the first energy storage resource attribute information A is [1000kW 50kW ]. Wherein, "1000kW" is the energy storage charge-discharge power upper limit value of power range. "50kW" is the energy storage charge-discharge power lower limit value of the power range. The first energy storage resource attribute information B includes energy storage charge and discharge power of [1200kw 60kw ]. The first energy storage resource attribute information C includes energy storage charge-discharge power of [1400kw 70kw ]. Thus, the first energy storage resource charge-discharge power information may be [ 360kw 180kw ].

Step 104, according to the second energy storage resource attribute information set, determining the energy storage resource capacity and the energy storage resource charging and discharging power of the energy storage resource corresponding to the second energy storage resource attribute information set, and obtaining second energy storage resource capacity information and second energy storage resource charging and discharging power information.

In some embodiments, the executing body may determine, according to the second energy storage resource attribute information set, an energy storage resource capacity and an energy storage resource charging/discharging power of the energy storage resource corresponding to the second energy storage resource attribute information set, to obtain second energy storage resource capacity information and second energy storage resource charging/discharging power information. The second energy storage resource capacity information represents the energy storage capacity of the energy storage medium corresponding to the second energy storage resource attribute information set. The second energy storage resource charging and discharging power information represents the power of the energy storage resource corresponding to the second energy storage resource attribute information set when the energy storage resource is charged and discharged in unit time. In practice, the energy storage medium of the energy storage resource corresponding to the second energy storage resource attribute information set may be water or a solid oxide.

As an example, first, for each second energy storage resource attribute information in the second energy storage resource attribute information set, a product of an energy storage capacity, an energy storage medium specific heat capacity, energy storage medium temperature information and energy storage medium density information included in the second energy storage resource attribute information is determined, and a product value is obtained. And secondly, determining the sum of all the product values in the obtained product value set as second energy storage resource capacity information. The execution body may determine a sum of energy storage electric load information included in each second energy storage resource attribute information in the second energy storage resource attribute information set as the second energy storage resource charge and discharge power information.

In some optional implementations of some embodiments, the executing body determines, according to the second energy storage resource attribute information set, an energy storage resource capacity and an energy storage resource charging/discharging power of an energy storage resource corresponding to the second energy storage resource attribute information set, to obtain second energy storage resource capacity information and second energy storage resource charging/discharging power information, and may include the following steps:

the first step, for each second energy storage resource attribute information in the second energy storage resource attribute information set, determining the product of energy storage capacity, energy storage medium specific heat capacity, energy storage medium temperature information and energy storage medium density information included in the second energy storage resource attribute information, and obtaining energy storage resource energy information.

The energy information of the energy storage resource is an energy range. The energy range includes: an energy storage resource energy upper limit value and an energy storage resource energy lower limit value.

As an example, the second set of energy storage resource attribute information may be [ second energy storage resource attribute information a ]. The energy storage capacity included in the second energy storage resource attribute information A is 10kJ, and the specific heat capacity of the energy storage medium included in the second energy storage resource attribute information A is 0.00418 kJ/(g.DEG C). The second energy storage resource attribute information A comprises energy storage medium temperature information of 100 ℃ and 0 ℃. The second energy storage resource attribute information A comprises energy storage medium density information of 1 g/cm. Thus, the energy information of the resulting energy storage resource may be [4180kJ 0kJ ]. Wherein 4180 kj=10× 0.00418 ×100×1.0 kj=10× 0.00418 ×0×1. Wherein, "4180kJ" is the energy upper limit value of the energy storage resource in the energy range. "50kW" is the energy lower limit of the energy storage resource in the energy range.

And a second step of determining the sum of energy information of each energy storage resource in the obtained energy information set of the energy storage resource as the total energy information of the energy storage resource.

In practice, the energy storage resource total energy information may characterize the total energy range. The total energy range includes: an upper energy storage resource total energy limit and a lower energy storage resource total energy limit.

As an example, the second set of energy storage resource attribute information may be [ second energy storage resource attribute information a, second energy storage resource attribute information B, second energy storage resource attribute information C ]. The energy information of the energy storage resource of the second energy storage resource attribute information A is [1000kJ 10kJ ]. Wherein, "1000kJ" is the energy upper limit value of the energy storage resource in the energy range. "10kJ" is the energy lower limit of the energy storage resource in the energy range. The energy storage resource energy information of the second energy storage resource attribute information B is [800kJ 20kJ ]. The energy information of the energy storage resource of the second energy storage resource attribute information C is 400kJ 30 kJ. Thus, the energy storage resource total energy information may be [2200kJ 60kJ ]. Wherein 2200 kj=1000+800+400. 60 kj=10+20+30. Wherein "2200kJ" is the upper limit value of the total energy of the energy storage resource in the total energy range. "60kJ" is the lower limit of the total energy of the energy storage resource in the total energy range.

And thirdly, determining the sum of energy storage electric load information included in each second energy storage resource attribute information in the second energy storage resource attribute information set as the total electric load information of the energy storage resources.

In practice, the energy storage resource total electrical load information may characterize the total electrical load range. The total electrical load range includes: an upper limit value of the total electric load of the energy storage resource and a lower limit value of the total electric load of the energy storage resource.

As an example, the second set of energy storage resource attribute information may be [ second energy storage resource attribute information a, second energy storage resource attribute information B, second energy storage resource attribute information C ]. The second energy storage resource attribute information A comprises energy storage electric load information of [1500kWh 10kWh ]. Where "1500kWh" is the upper limit value of the electrical load for the electrical load range. "10kWh" is the lower limit value of the electrical load for the electrical load range. The second energy storage resource attribute information B comprises energy storage electric load information of [1200kWh 20kWh ], and the second energy storage resource attribute information C comprises energy storage electric load information of [1000kWh 30kWh ]. Thus, the energy storage resource total electrical load information may be [3700kwh 60kwh ]. Therein 3700 kwh=1500+1200+1000. 60 kwh=10+20+30. Where "3700kWh" is the energy storage resource total electrical load upper limit for the total electrical load range. "60kWh" is the energy storage resource total electrical load lower limit value for the total electrical load range.

And step four, performing energy unit mapping on the total energy information of the energy storage resources to generate the second energy storage resource capacity information.

The execution body may perform energy unit mapping on the total energy information of the energy storage resource through an energy unit mapping formula to generate the second energy storage resource capacity information. The energy unit mapping formula is as follows: s=q×0.00028. Wherein Q is total energy information of the energy storage resource, and S is capacity information of the second energy storage resource.

In practice, the second energy storage resource capacity information may characterize an energy storage capacity range of the energy storage resource.

As an example, the energy storage resource total energy information may be [2200kJ 60kj ]. Thus, the second energy storage resource capacity information may be [0.616kWh 0.0168kWh ]. Wherein 0.616 kwh=2200×0.00028.0.0168 kwh=60×0.00028. Here, "0.616kWh" is the upper limit value of the energy storage capacity in the rated capacity range. "0.0168kWh" is the lower limit of the energy storage capacity in the rated capacity range.

And fifthly, carrying out load unit mapping on the total electric load information of the energy storage resources to generate the charge and discharge power information of the second energy storage resources.

The execution body may perform load unit mapping on the total electrical load information of the energy storage resource through a load unit mapping formula, so as to generate the charging and discharging power information of the second energy storage resource. The load unit mapping formula may be: w=e≡t. Wherein E is the energy storage resource total electrical load information. T is time. W is the charging and discharging power information of the second energy storage resource.

In practice, the second energy storage resource charging and discharging power information may represent an energy storage charging and discharging power range of the energy storage resource.

As an example, the energy storage resource total electrical load information may be [3700kwh 60kwh ], and the time may be 2h. Thus, the second energy storage resource charge-discharge power information may be [1850kw 30kw ]. Wherein 1850kW =3700++2. 30 kw=60++2. "1850 kW" is the upper limit value of the stored charge and discharge power in the power range. And 30kW is the lower limit value of the energy storage charge and discharge power in the power range.

And 105, taking the charge and discharge power information of the first energy storage resource and the charge and discharge power information of the second energy storage resource as constraints, and generating load limit information according to the capacity information of the first energy storage resource and the capacity information of the second energy storage resource.

In some embodiments, the executing entity may generate the load limitation information based on the first energy storage resource capacity information and the second energy storage resource capacity information with the first energy storage resource charge and discharge power information and the second energy storage resource charge and discharge power information as constraints. Wherein the load limitation information includes: upper load limit information and lower load limit information. The load limitation information characterizes the load (load) carrying capacity of the target circuit network during the power supply. The load upper limit information characterizes the load upper limit value of the target circuit network in the power supply process. The load lower limit limiting information characterizes a load lower limit value of the target circuit network in the power supply process. In practice, the upper load limit information may characterize the maximum discharge power. The lower load limit information may characterize the minimum discharge power.

In practice, the executing body may use the sum of the first energy storage resource charging and discharging power information and the second energy storage resource charging and discharging power information as the constraint condition of the adjustable power, and obtain the load limitation information according to the quantity relation of the first energy storage resource capacity information, the second energy storage resource capacity information, the adjustable power and the adjustable duration (the sum of the first energy storage resource capacity information and the second energy storage resource capacity information is equal to the product of the adjustable power and the adjustable duration). The adjustable power may be a power value in an adjustable power range of the target circuit network. By substituting a plurality of adjustable powers, a power range for power adjustment is thus available as load limitation information. Further, the adjustable duration may be a corresponding duration for power adjustment of the target circuit network.

In some optional implementations of some embodiments, the executing body may generate the load limitation information based on the first energy storage resource capacity information and the second energy storage resource capacity information with the first energy storage resource charge and discharge power information and the second energy storage resource charge and discharge power information as constraints, and may include the following steps:

And determining the sum of the charge and discharge power information of the first energy storage resource and the charge and discharge power information of the second energy storage resource as third energy storage resource charge and discharge power information.

As an example, the first energy storage resource charge-discharge power information may be [3600kw 180kw ]. The second energy storage resource charge-discharge power information may be [1850kw 30kw ]. Thus, the third energy storage resource charge-discharge power information may be [5450kw 210kW ]. Wherein 5450 kw=3600+1850. 210 kw=180+30. Wherein, "5450kW" is the upper limit value of the energy storage charging and discharging power in the power range. And 210kW is the lower limit value of the energy storage charging and discharging power in the power range.

And a second step of determining the sum of the first energy storage resource capacity information and the second energy storage resource capacity information as third energy storage resource capacity information.

As an example, the first energy storage resource capacity information may be [1000kwh 60kwh ]. The second energy storage resource capacity information may be [0.616kWh 0.0168kWh ]. Thus, the third energy storage resource capacity information may be [1000.616kWh 60.0168kWh ]. Wherein 1000.616 kwh=1000+0.616. 60.0168 kw=60+0.0168. Here, "1000.616kWh" is the upper limit value of the energy storage capacity in the rated capacity range. "60.0168" is the lower limit value of the storage capacity in the rated capacity range.

And thirdly, taking the charge and discharge power information of the third energy storage resource as power constraint, and generating the load limit information according to the capacity information of the third energy storage resource.

Wherein the execution subject may generate the load restriction information through a load restriction information generation formula. Wherein, the load limit information generation formula is: s=p×t. Wherein S is third energy storage resource capacity information. P is the adjustable power of the target circuit described above. T is the adjustable duration of the target circuit described above.

As an example, the third energy storage resource capacity information may be [1200kwh 80kwh ]. The third energy storage resource charge-discharge power information may be [5000kw 200kw ]. Therefore, the value range of P is [5000kw 200kw ], and the generation formula can be obtained from the above-described limit information: 1200 =p×t and 80=p×t. When T is fixed, a plurality of P (adjustable power of the target circuit) can be obtained as load limitation information. Therefore, a plurality of load upper limit values can be obtained as the load upper limit restriction information. A plurality of load lower limit values can be obtained as the load lower limit restriction information.

In practice, the adjustable duration (T) may be a continuous period of time, in particular, the adjustable duration (T) may be divided into K sub-adjustable durations, i.e. the adjustable duration may be [ T ] ₁ ，T ₂ …T _K ]. Wherein the sub-adjustable duration T ₁ Can be corresponding to P ₁ (sub-adjustable power). Sub-adjustable duration T ₂ Can be corresponding to P ₂ (sub-adjustable power). Sub-adjustable duration T _K Can be corresponding to P _K (sub-adjustable power). Wherein each sub-adjustable power may be a constant power value. For example, P ₂ =210 kW. Thus, the load limit information generation formula described above can be converted into s=t ₁ ×P ₁ + T ₂ ×P ₂ +…+ T _K ×P _K In the form of (a).

As an invention point of the present disclosure, the content of "some optional implementation manners of some embodiments" in steps 103 to 105 solves the second technical problem mentioned in the background art, that is, "the energy storage types corresponding to the energy storage resources are numerous, and the power supply capacities of the different energy storage resources are different, often the power supply capacities of the energy storage resources of the different energy storage types cannot be comprehensively considered, so that when the electric energy requirement is large, the power adjustment cannot be performed on the circuit network timely and accurately. In practice, the energy storage types corresponding to the energy storage resources can be electrochemical energy storage, thermal energy storage and mechanical energy storage, and due to different energy storage mediums corresponding to the energy storage resources, different availability degrees, different scales and different numbers, different power supply capacities of the energy storage resources are often caused, and the situation that accurate power information cannot be generated due to the fact that the power supply capacities of the energy storage resources of different energy storage types cannot be considered integrally is caused. Based on this, first, the disclosure divides the energy storage resource attribute information set according to the energy storage type included in the energy storage resource attribute information set, to obtain a first energy storage resource attribute information set and a second energy storage resource attribute information set, where the energy storage resource corresponding to the first energy storage resource attribute information set is an electrochemical energy storage resource, and the energy storage resource corresponding to the second energy storage resource attribute information set is a thermal energy storage resource. Because the electrochemical energy storage resource and the thermal energy storage resource have larger holding quantity and more energy storage resources, the power adjustment of the target circuit network can be quickly and effectively carried out by combining the electrochemical energy storage resource and the thermal energy storage resource. And secondly, because the normal operation of the power supply system is not separated from capacity and power, and the energy storage resources corresponding to the energy storage types in the first energy storage resource attribute information set are energy storage resources which store energy in a chemical form so as to be converted into electric energy when required, the first energy storage resource attribute information set contains at least one first energy storage resource attribute information, and therefore the energy storage capacity integral summation included in each first energy storage resource attribute information in the first energy storage resource attribute information set and the energy storage charging and discharging power integral summation included in each first energy storage resource attribute information in the first energy storage resource attribute information set are carried out to obtain the first energy storage resource capacity information and the first energy storage resource charging and discharging power information. Then, because the energy storage resource corresponding to the energy storage type in the second energy storage resource attribute information set is an energy storage resource for storing energy in a thermal form so as to be converted into electric energy or heat energy when needed, energy storage resource energy information needs to be generated according to the product of the energy storage capacity, the specific heat capacity of the energy storage medium, the temperature information of the energy storage medium and the density information of the energy storage medium included in each second energy storage resource attribute information in the second energy storage resource attribute information set; and summing energy information of each energy storage resource in the obtained energy storage resource energy information set to obtain total energy information of the energy storage resource, and performing energy unit mapping on the total energy information of the energy storage resource to generate the second energy storage resource capacity information for convenience of unified scheduling control. And the second energy storage resource charging and discharging power information is obtained by summing energy storage electric load information included in each second energy storage resource attribute information in the second energy storage resource attribute information set so as to generate energy storage resource total electric load information and mapping load units of the energy storage resource total electric load information. Further, the first energy storage resource charging and discharging power information and the second energy storage resource charging and discharging power information are taken as constraints, and load limiting information is generated according to the first energy storage resource capacity information and the second energy storage resource capacity information. By integrating the energy storage resource capacity information and the energy storage resource charging and discharging power information of the two energy storage resources, the generated load limit information is more accurate, and the hardware damage to the target circuit network or the energy storage resources caused by overload adjustment is avoided. In summary, by generating accurate load limitation information, accurate power adjustment information can be generated laterally to realize adjustment of power of a target circuit network, so that the problem that equipment connected with the circuit network is possibly damaged is avoided to a certain extent, and equipment in the circuit can be protected.

In practice, the power adjustment information may include a power adjustment range. In practice, the execution body determines a difference between the load upper limit information and the standard load curve and a difference between the standard load curve and the load lower limit information as the power adjustment information.
