[0050] The energy storage configuration method and system for supporting distributed power consumption in an intelligent park provided by the application, as shown in the method flowchart, Figure 1 the system structure diagram, Figure 5 the specific scheme is as follows:

[0051] Step 1: Obtain the actual output of distributed power generation, the actual value of demand-side load power, and the pre-calculated assumed output of distributed power generation and the ideal predicted value of demand-side load power at the current time;

[0052] Step 2: Obtain the distributed power generation output error at the current time based on the actual output of distributed power generation and the assumed output of distributed power generation at the current time, and obtain the demand-side load power error at the current time based on the actual value of demand-side load power and the ideal predicted value of demand-side load power at the current time;

[0053] Step 3: When the distributed power generation output error is greater than a first set threshold: based on the energy storage distributed power consumption group, stepwise consume the distributed power generation output error at the current time;

[0054] Step 4: When the demand-side load power error is greater than a second set threshold: based on the energy storage demand-side resource group, stepwise consume the demand-side load power error at the current time.

[0055] Step 1: Obtain the actual output of distributed power generation, the actual value of demand-side load power, and the pre-calculated assumed output of distributed power generation and the ideal predicted value of demand-side load power at the current time:

[0056] (I) Classification of information required for configuration scheme

[0057] (1) Operation information of backup rotating generator set participating in adjustment determined by power grid

[0058] The operation information of the backup rotating generator set participating in adjustment includes the power generation output of each generator set, the upper and lower limits of power generation technical output (maximum power generation technical output and minimum power generation output), the upper limit of climbing output capability, and the lower limit of reducing output capability, and the technical output range.

[0059] (2) Operation information of power grid predicted distributed power generation output and demand-side resource

[0060] The operation information of distributed power generation output and demand-side resource includes the ideal predicted value of assumed output of distributed power and the number of participating users |L| of demand-side resource, and the ideal load power that can be expected to participate in adjustment

[0061] Step 2: Obtain the distributed power generation output error at the current time based on the actual output of distributed power generation and the assumed output of distributed power generation at the current time, and obtain the demand-side load power error at the current time based on the actual value of demand-side load power and the ideal predicted value of demand-side load power at the current time:

[0062] (3) Error of grid determining distributed power generation and demand side resource configuration

[0063] Error of distributed power generation and demand side resource configuration. Error includes demand side load adjustment error and distributed power consumption error Demand side load adjustment error is the ideal load power of load adjustment and the actual adjusted load power Distributed power consumption is the ideal prediction value of distributed power assumed output by the grid through analysis and the actual distributed power output The difference between the two.

[0064] (2) Dynamic grouping of decentralized energy storage devices

[0065] Dynamic grouping of decentralized energy storage devices: energy storage devices are divided into two large groups, each large group corresponding to two small groups. Two large groups correspond to distributed power consumption group and demand side resource matching group.

[0066] Step 3: When the distributed power output error is greater than the first set threshold: based on the energy storage distributed power consumption group, the distributed power output error at the current time is stepped up:

[0067] The distributed power consumption group mainly undertakes the consumption of the distributed power to avoid stability problems caused by large-scale access of distributed power, and then transmits power according to the specific operation mode of the grid. When the distributed power consumption error occurs, start to consume the distributed power and stop power transmission to the grid.

[0068] Step 4: When the demand side load power error is greater than the second set threshold: based on the energy storage demand side resource group, the demand side load power error at the current time is stepped up:

[0069] The demand side resource group mainly makes up the power shortage when the demand side users use energy, and absorbs power from the grid at ordinary times. When the demand side load adjustment error occurs, stop charging and start discharging to supply energy to the grid.

[0070] The two small groups include: fast regulation energy storage group and ordinary regulation energy storage group.

[0071] (3) Stepwise consumption and matching error of decentralized energy storage devices

[0072] The charging rule of the distributed power consumption group at time t is to prioritize the fast regulation energy storage group to the ordinary regulation energy storage group in the positive sequence mode. The charging and discharging capacity is not at the upper and lower limits. The discharging rule of the demand side resource matching group at time t is to prioritize the ordinary regulation energy storage group to the fast regulation energy storage group in the positive sequence mode.

[0073] The ladder mainly refers to the dynamic change of the distributed power consumption group and the demand side resource matching group at each moment.

[0074] Embodiment 2:

[0075] Figure 2 A support intelligent park distributed power consumption energy storage configuration scheme implementation system flowchart according to an embodiment of the application. The scheme considers the uncertainty of distributed power and demand response resource configuration. As shown in Figure 2 , it is assumed that there are |K i | energy storage devices, and k represents the |K| energy storage device number. There are |J| generator groups to supply the load of the users of the park, and the set J can represent the generator group set. The generator group provides necessary grid stability control services such as frequency regulation and voltage regulation for distributed power consumption. j represents the jth generator group. There are |L| users participating in demand response, and l represents the lth user participating in demand response. The length of time during the entire grid dispatching and control process is |T|, and similarly, t represents the time of the tth demand response execution, and T represents the demand response execution time set.

[0076] For the convenience of subsequent patent understanding, the symbol B represents the energy storage device, the symbol G represents the generator group, the symbol D represents the distributed power, and the symbol DS represents the demand side resource. The above symbols will represent the models of the above four entities in the following formulas.

[0077] The focus of this patent is to solve the problem of balancing the load power of the four entities through the matching of backup rotating generator groups, energy storage devices, distributed power, and demand side resources.

[0078]

[0079] To Figure 3 introduce the energy storage configuration method and specific implementation process for solving the problem. As shown in Figure 3 , the method 200 is from step 201 to 206. Start with 201: first, the grid dispatching and control platform center determines the power generation output of each generator group of the |J| generator groups, the upper and lower limits of the power generation technology output (the maximum power generation technology output and the minimum power generation output), the upper limit of the climbing output capacity, and the lower limit of the reducing output capacity, etc.

[0080] The power generation output of the jth generator group at the tth moment is Similarly, the power generation technology output of the generator set has an upper and lower limit. The maximum power generation technology output and the minimum power generation technology output And

[0081]

[0082] If the jth generator set generates power at this time, its corresponding power generation capacity has an upper limit The output of the generator set at time t Should not be higher than the output at the previous t-1 time Too much. The relationship between the above And Can be represented by equation (3).

[0083]

[0084] If the jth generator set generates power at this time, its corresponding power generation capacity has an upper limit The output of the generator set at the previous t-1 time Should not be lower than the output at time t Too much. Similarly, at this time, the relationship between the above And Can be represented by equation (4).

[0085]

[0086] Due to the particularity of the generator set, it cannot be started and stopped frequently. Therefore, the load power of the generator set from a certain time t to T G Period cannot differ too much, that is, it cannot exceed the technical output range of the generator set And cannot be 0.

[0087]

[0088] Similarly, at this time, the total output load of all generator sets at time t Is:

[0089]

[0090] Step 202: After determining the operation information of the standby rotating generator set participating in distributed power consumption, the grid dispatching and control platform center starts to predict the operation information of the distributed power generation output and the demand side resources. The information includes the ideal predicted value of the assumed output of the distributed power source And the number of users participating in adjustment |L| and the expected load power that can participate in adjustment of the demand side resources

[0091] Step 203: The grid dispatch control platform center starts to dynamically and real-timely collect information about actual power generation of distributed power supply and adjustment of demand side resource. The specific information includes actual distributed power supply output and actual load power of demand side resource adjustment By determining the actually collected information, the error in the matching process of distributed power supply generation and demand side resource, i.e. the demand side load adjustment error and the distributed power supply consumption error is confirmed. The specific details are as follows:

[0092] The ideal predicted value of the output of distributed power supply is assumed to be while the actual distributed power supply output is The basic proportion of grid access of distributed power supply at this time is μ. The basic proportion and the ideal load power of demand side load adjustment are related.

[0093]

[0094] However, the actual distributed power supply output collected and obtained by the grid unified dispatch control platform in real time at this time is At this time, there is a certain error

[0095]

[0096] The load adjustment of user l of the |L| users of demand side resource is At this time, the demand side participates in the consumption of distributed power supply, and uses the |L| users that have been determined to participate in demand response but are uncertain about the specific participation capacity at each time t to realize the matching of demand side resource and distributed power supply curve.

[0097] It is assumed that the actual load that can be adjusted by user l at time t is The ideal adjusted load power of demand side resource in anticipation is

[0098] The grid unified dispatch control platform real-timely collects information and statistics that the demand side load resource can adjust at time t to consume distributed power supply. At this time, the overall adjustment error is

[0099]

[0100] After analyzing the load adjustment error in the demand side load resource response process and the error in the distributed power supply consumption, the two error adjustment elimination can be realized by using energy storage devices.

[0101] Step 204: The grid dispatch control platform centrally integrates the operation information of the distributed cluster energy storage devices participating in demand response regulation, and the operation information includes the maximum technical output, the minimum technical output, the discharge power, the stored power of a single energy storage device, the maximum storage capacity of all energy storage devices, and the overall energy storage level setting threshold.

[0102] Step 205: After the grid dispatch control platform centrally integrates the operation information of the distributed cluster energy storage devices participating in demand response regulation, the multi-region energy storage devices are grouped and processed, and a total of 4 groups are divided. 2 large groups, each corresponding to 2 small groups. The 2 large groups correspond to the distributed power consumption group and the demand side resource matching group. The distributed power consumption group mainly undertakes the consumption of distributed power to avoid stability problems caused by large-scale access of distributed power, and then transmits power according to the specific operation mode of the grid. When the distributed power consumption error occurs, the distributed power consumption group in the energy storage device starts to consume the distributed power, and stops the power transmission of the distributed power consumption group in the energy storage device to the grid. The demand side resource group mainly makes up for the power shortage when the demand side users use energy, and absorbs power from the grid at ordinary times. When the demand side load adjustment error occurs, stop charging and start discharging power to the grid. The 2 large groups are divided into 2 groups based on the preset value of the consumption speed. Therefore, the distributed cluster energy storage devices have a total of 4 small groups. The small group division rule in the large group is that the first small group is a fast regulation energy storage group, and the second small group is a normal regulation energy storage group. The fast regulation energy storage group can realize fast discharge or charge, and the normal regulation energy storage group is relatively slow in charging and discharging. The grouping method is: first, group the energy storage devices contained in the distributed power consumption group and the demand side resource matching group. The grouping method is classified according to the response matching speed of the energy storage device and the current energy storage level. It is divided into a fast regulation energy storage group FD and a normal regulation energy storage group ND.

[0103] If the current energy storage capacity of the kth energy storage device at time t is the energy storage limit of the energy storage device is the energy storage level a is

[0104]

[0105] The distributed power consumption group energy storage device is mainly used for the consumption of distributed power, so the lower the energy storage level at this time means the greater the energy storage charging potential. It is stipulated that if the energy storage level a of the distributed power consumption group energy storage device is less than and the energy storage capacity does not reach the energy storage limit that is If the kth energy storage device belongs to the distributed power consumption group and has a fast response matching speed, it is classified into the fast dispatching and regulating energy storage group FD; otherwise, it is classified into the normal dispatching and regulating energy storage group ND.

[0106] The energy storage device of the demand side resource matching group is mainly used for matching the demand side resource, and thus a higher energy storage level means a greater discharging potential of the energy storage. The energy storage device of the demand side resource matching group is regulated as follows: if the energy storage level a is greater than and the energy storage capacity does not reach the energy storage limit that is, If the kth energy storage device belongs to the demand side resource matching group and has a fast response matching speed, it is classified into the fast dispatching and regulating energy storage group FD; otherwise, it is classified into the normal dispatching and regulating energy storage group ND.

[0107] After the dynamic grouping of the distributed energy storage device, the power grid starts to consume and match the load error caused by the uncertainty of the distributed power and demand side resource. The whole process adopts the dynamic grouping and stepwise consumption and matching of the uncertainty of the load error caused by the consumption and matching of the demand side resource and distributed power The specific execution process of the dynamic grouping and stepwise consumption and matching of the error of the distributed energy storage device is as follows:

[0108] The energy storage device of the distributed power consumption group is regulated as follows: no matter whether it belongs to the fast dispatching and regulating energy storage group FD or the normal dispatching and regulating energy storage group ND, the maximum charging consumption capacity and the minimum charging consumption capacity of the energy storage device during the charging process should satisfy the constraint of formula (11).

[0109]

[0110] The overall chargeable consumption capacity of the distributed power consumption group is

[0111]

[0112] In the manner of Figure 4 , the charging rule of the distributed power consumption group at time t is in the positive sequence manner, which gives priority to the fast dispatching and regulating energy storage group to the normal dispatching and regulating energy storage group. At time t+1, the grouping of the energy storage device of the distributed power consumption group is updated according to step 205.

[0113] The energy storage device of the demand side resource matching group is mainly used for making up the power shortage caused by the energy use of the demand side user and absorbing the power in the power grid. The overall energy storage device of the demand side resource matching group is regulated as follows: no matter whether it belongs to the fast dispatching and regulating energy storage group FD or the normal dispatching and regulating energy storage group ND, the maximum technical output and the minimum technical output The constraint of formula (13) should be satisfied.

[0114]

[0115] The overall dischargeable matching capability of the demand side resource matching group is

[0116]

[0117] In the manner of Figure 4 The discharge rule of the demand side resource matching group at time t is in the manner of giving priority to normal regulation energy storage groups to fast regulation energy storage group regulation in sequence. The energy storage device grouping of the demand side resource matching group is updated at time t+1 according to step 205.
