Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent to one skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.

An energy storage planning system and method according to embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an energy storage planning system according to an embodiment of the present disclosure. As shown in fig. 1, the energy storage planning system includes:

the data acquisition module 101 is configured to acquire the time-sharing stored energy value and the time-sharing discharged energy value of each operation period of the energy storage device in a preset operation cycle, and historical energy utilization data of an energy utilization party.

The energy storage device can be an electric energy storage device, a natural gas energy storage device and the like. The electric energy storage device is an energy storage device taking electric energy as input and output, and is generally a battery based on a chemical principle, and the electric energy storage device does not comprise heat storage and cold storage devices (inputting electric energy and outputting heat energy) such as an electric water heater and kinetic energy storage potential energy devices (inputting electric energy and outputting kinetic energy) such as flywheel compressed air.

The preset operation period can be flexibly set according to the actual situation. For example, it may be set to 1 day, 1 year, etc., without limitation.

The operation period specifically refers to dividing the operation cycle into a plurality of time segments according to a certain time span, for example, the operation cycle is 1 day, and may be a time segment according to 1 hour, and dividing 1 day into 24 hours, for a total of 24 time segments. Of course, 1 quarter clock (i.e. 15 minutes) can be used as a time slice, and 1 day can be divided into 96 quarter clocks for 96 time slices.

The time-sharing energy storage value refers to the energy storage value (for example, the predicted charging price) corresponding to each time segment, which is obtained by dividing the above one operation cycle (for example, 1 day) into 24 time segments (each time segment is 1 hour).

The time-sharing discharge value refers to that one operation cycle (for example, 1 day) is divided into 24 time segments (each time segment is 1 hour), and the discharge value (for example, the predicted discharge electricity price) corresponding to each time segment.

The energy consumption method generally refers to a method of using energy, for example, an electricity consumption unit or an individual, a gas consumption unit or an individual, and the like.

Historical energy usage data includes time periods and usage amounts of energy (e.g., electrical energy, etc.) used by the energy consumers. For example, the historical electricity consumption data of each hour from 1 month, 1 day, 0 hour to 24 hours in the past 20xx year of a certain electricity consumption company A.

As an example, the charging price (or directory charging price, i.e. time-of-use energy value) and the discharging price (or directory discharging price, i.e. time-of-use energy value) of an operation cycle of 1 day published by an energy supplier (i.e. an energy supplier, e.g. a commercial power seller) can be obtained through internet technology. Meanwhile, historical electricity utilization data of an energy utilization party (such as an electricity utilization party) can be acquired through the Internet of things sensing equipment, a big data platform and the like.

The discharging strategy determining module 102 is configured to determine a discharging strategy of the energy storage device in each planned discharging duration according to a plurality of preset planned discharging durations, time-sharing discharging values and historical energy utilization data, where the discharging strategy includes at least one discharging time period and a discharging amount corresponding to each discharging time period.

The planned discharging duration generally refers to a total duration of continuous or discontinuous discharging of the energy storage device in a preset operation period. For example, when the operation period is 1 day, the planned put-down time period may be 1,2, 3,4 … 24 hours, and the planned put-down time period cannot exceed the time length of the operation period, i.e., not exceed 24 hours.

For example, in practical application, a planned energy release duration may be first specified, and typically, an initial value may be specified as 1 hour. Then, according to the specified planned discharging time length, the obtained time-sharing discharging values (for example, discharging prices corresponding to each time segment from 0 hour to 24 hours) of each operating period (1 hour is one operating period) of the energy storage device in an operating cycle (for example, 1 day), and historical electricity consumption data of the electricity consumers, a discharging strategy 01 under the planned discharging time length of 1 hour is determined (that is, at least one discharging time length under the planned discharging time length of 1 hour and the discharging energy corresponding to each discharging time length). Next, the planned discharging duration is adjusted to be 2 hours, and then the discharging strategy 02 under the planned discharging duration of 2 hours is determined according to the above steps (i.e., at least one discharging period and the discharging amount corresponding to each discharging period under the planned discharging duration of 2 hours).

The discharging time interval may be one or more of the above operation time intervals. For example, it may be 0 (here, it is considered that there are 1 discharge periods), or the first quarter clock and the second quarter clock in 0 (here, it is considered that there are two discharge periods).

The corresponding energy release amount in each time interval can be 10%, 30%, 50%, 100% and the like. For example, when the discharging time interval is 0, the corresponding discharging amount is 100%.

In addition, unlike energy storage, energy discharge is constrained by the amount of load, and if there is no load demand at a certain time, discharge cannot be performed. Therefore, the dump period cannot be a period of time without load demand.

The energy storage strategy determining module 103 is configured to determine an energy storage strategy of the energy storage device in each planned energy storage duration according to a plurality of preset planned energy storage durations, time-sharing energy storage values and energy release strategies, where the energy storage strategy includes at least one energy storage period and energy storage corresponding to each energy storage period.

The planned energy storage duration generally refers to a total duration of continuous or discontinuous energy storage of the energy storage device in a preset operation period.

In practical application, firstly, the planned energy storage duration can be determined according to the planned energy release duration; then, according to the planned energy storage duration, the obtained time-sharing energy storage value (for example, a charging price corresponding to each time slice from 0 hour to 24 hours) of each operation period (1 hour is one operation period) of the energy storage device in an operation cycle (for example, 1 day), and the determined energy release strategy under each planned energy release duration, an energy storage strategy under each planned energy storage duration (that is, a plurality of energy storage periods under each planned energy storage duration and the energy storage corresponding to each energy storage period) is determined.

For example, assuming that the planned energy release duration is 1 hour, determining that the planned energy storage duration is 30min according to the planned energy release duration, then further determining an energy storage policy 01 under the planned energy storage duration of 30min (i.e., at least one energy storage period and the energy storage amount corresponding to each energy storage period under the planned energy storage duration of 30min) according to the obtained time-sharing energy storage values (e.g., the charging prices corresponding to each time segment from 0 hour to 24 hours) of the energy storage devices in each operation period (1 hour is one operation period) within the operation cycle (e.g., 1 day) and the energy release policy 01.

The energy storage period may be one or more of the above operation periods. For example, it may be 0 (here, it is considered that there are 1 energy storage period), or the first quarter clock and the second quarter clock in 0 (here, it is considered that there are two energy storage periods).

The energy stored in each time interval can be 10%, 30%, 50%, 100% and the like. For example, the energy storage time period is 0 in the first quarter clock, which corresponds to 50% of the energy storage amount, and the energy storage amount in the second quarter clock is 10%.

A capacity requirement determination module 104 configured to determine an energy storage capacity requirement of the energy storage device during the operation period according to the discharging strategy and the energy storage strategy.

The energy storage capacity requirement generally refers to the maximum energy throughput required for the energy storage device to operate stably during the operating period.

As an example, according to the energy release strategy and the energy storage strategy determined in the above steps, a continuous energy release period and a continuous energy storage period are found, and the energy sum of the continuous energy release period and the energy sum of the continuous energy storage period are respectively calculated, and then the energy storage capacity requirement of the energy storage device in an operating cycle (e.g. 1 day) is determined according to the energy sum of the continuous energy release period and the energy sum of the continuous energy storage period.

The establishing module 105 is configured to establish an associated logical relationship among the planned discharging time, the planned energy storage time, the discharging strategy, the energy storage strategy, and the energy storage capacity requirement.

As an example, a table of associated logic relationships of the planned discharging time length, the planned energy storage time length, the discharging strategy, the energy storage strategy and the energy storage capacity requirement shown in table 1 below may be established.

TABLE 1 associated logical relationship Table

And the scheme determining module 106 is configured to obtain an operation optimization adjustment target of the energy storage device, and determine an optimal planning scheme of the energy storage device in an operation cycle according to the operation optimization adjustment target, the association logic relationship, the time-sharing capacity value and the time-sharing storage value.

The operation optimization adjustment target generally refers to an index of the operation investment and the income of the energy storage device, and may be, for example, a gross profit (daily profit), a return on investment period, a total income of a project, and the like.

The optimal planning scheme can be determined by screening a plurality of energy release strategies under the planned energy release duration and a plurality of energy storage strategies under the planned energy storage duration according to the steps, and then further screening a comprehensive scheme of the energy storage strategy and the energy release strategy, which meets the operation optimization adjustment objective and can achieve the maximum benefit of the operation optimization adjustment objective, by combining the set operation optimization adjustment objective (such as Nissan). That is, in an operation cycle (e.g. 1 day), which operation period can store more energy, which period can store more energy.

According to the technical scheme provided by the embodiment of the disclosure, the time-sharing energy storage value and the time-sharing energy release value of each operation time period of the energy storage device in a preset operation cycle and historical energy use data of an energy using party are obtained through the data obtaining module; the energy release strategy determining module determines an energy release strategy of the energy storage equipment in each planned energy release duration according to a plurality of preset planned energy release durations, time-sharing energy release values and historical energy utilization data, wherein the energy release strategy comprises at least one energy release time period and energy release amount corresponding to each energy release time period; the energy storage strategy determining module determines an energy storage strategy of the energy storage equipment in each planned energy storage time length according to a plurality of preset planned energy storage time lengths, time-sharing energy storage values and energy release values, wherein the energy storage strategy comprises at least one energy storage time period and energy storage corresponding to each energy storage time period; the capacity requirement determining module determines the energy storage capacity requirement of the energy storage equipment in the operation period according to the energy release strategy and the energy storage strategy; the establishing module establishes an associated logic relationship among the planned energy release time length, the planned energy storage time length, the energy release strategy, the energy storage strategy and the energy storage capacity requirement; the scheme determining module obtains an operation optimization adjusting target of the energy storage equipment, determines an optimal planning scheme of the energy storage equipment in an operation period according to the operation optimization adjusting target, the association logic relationship, the time-sharing discharge value and the time-sharing storage value, can meet diversified requirements of energy storage planning construction of various energy sources, particularly new energy sources, and can enable the energy storage operation of the energy storage equipment to achieve optimal configuration, so that the operation stability of the energy storage equipment is improved, and benefit maximization of energy circulation utilization is facilitated.

In some embodiments, the enabling policy determining module 102 includes:

the energy utilization determining unit is configured to determine an energy utilization period of an energy utilization party and corresponding energy utilization thereof according to historical energy utilization data;

the sequencing unit is configured to sequence the time-sharing potential values of the operation time periods in a high-to-low order to obtain a first sequencing result;

and the discharging strategy determining unit is configured to determine at least one discharging time interval of the energy storage device in each planned discharging time length and the discharging energy corresponding to each discharging time interval according to the energy using time intervals and the energy using energy corresponding to the energy using time intervals.

As an example, an energy consumption load curve (e.g., an electricity consumption load curve) may be drawn according to the acquired historical energy consumption data (e.g., historical electricity consumption data) of the energy consumption party, where an abscissa of the curve may be an electricity consumption time period (e.g., 0 hour, 1 hour, 2 hours … 24 hours), and an ordinate may be energy consumption (e.g., electricity consumption). According to the power load curve, the power consumption of the power consumer in each power consumption period can be clearly understood. Or, the electricity consumption time interval of the next operation cycle and the corresponding electricity consumption can be estimated according to the energy consumption load curve.

Then, sorting is performed according to the time-sharing discharge value (for example, the discharge price of each operation period is set to be 1 hour as one operation period, and 24 operation periods are totally set in one day, namely, 24 discharge prices are correspondingly set), and a first sorting result, namely, a time-sharing discharge value priority level time sequence is obtained

Wherein the content of the first and second substances,

represents the time-sharing discharge value (discharge price) at the j-th operation period.

And then, determining at least one discharging time interval and the discharging amount corresponding to each discharging time interval according to the power consumption and the time-sharing discharging value priority of the power utilization party in each power utilization time interval. Specifically, at least one discharging period may be determined according to the electricity usage period of the electricity consumer. When the electricity consumer uses electricity, the energy supplier or the energy storage device discharges electricity.

As an example, assuming that the electricity consumption periods of the electricity consumers are 0,1, 12, 16 and 18, the electricity consumption amount corresponding to each electricity consumption period is A, B, C, D, E, the planned discharging time period is 1 hour, and the operation period sequence in the time-sharing discharging value priority sequence, which is sorted from high to low, is [0(24),2,3,4,5,8,10,12,11,16,18,13,6,7,22,21,20,19,17,16,14,15,23,1 ]. The discharge period of the energy storage device may be 0 hours (with a time span of 1 hour) with a corresponding discharge amount equal to or greater than a. The rest of the electricity utilization periods (1, 12, 16 and 18) can adopt a commercial power supply mode to provide electric energy for the power consumers.

As another example, assuming that the operation period sequence in the time-sharing discharging value priority sequence is [0(24),1,3,4,5,8,10,12,11,16,18,13,6,7,22,21,20,19,17,16,14,15,23,2] in order from high to low, the discharging period of the energy storage device may be 0 hours (with a time span of 30min), the corresponding discharging amount is equal to or greater than a, and 1 hour (with a time span of 30min), and the corresponding discharging amount is equal to or greater than B. The rest of the power utilization periods (12, 16 and 18) can adopt a commercial power supply mode to provide electric energy for the power utilization party.

That is to say, in the aspect of the energy using party, the main principle of the energy discharging strategy is to select the energy storage device to supply power to the energy using party when the discharging price is high, which is beneficial to reducing the electricity consumption cost of the energy using party. And stand in the angle of energy supply side, put the main principle of energy strategy and be when the price of discharging is higher, for the energy utilization side more energy supply (put the energy), be favorable to improving the income of energy supply side like this.

In some embodiments, the discharge policy determining unit is specifically configured to:

calculating to obtain a plurality of planned energy storage durations according to a preset energy storage and storage time ratio and the plurality of planned energy release durations;

and determining at least one energy storage time period of the energy storage equipment in each planned energy storage time length and the energy storage corresponding to each energy storage time period according to the release energy and the time-sharing energy storage value corresponding to each release time period.

The energy storage time ratio refers to the time ratio of energy storage (charging) to energy discharge (discharging) of an energy storage device (e.g., an electric energy storage device), and is denoted as R_c. For example, the charge-discharge time ratio, which is numerically equal to "recommended discharge current/recommended charge current".

As an example, the energy release duration T may be based on each plan_outAnd calculating a corresponding planned energy storage time length according to a preset energy storage time ratio, and solving m according to the planned energy storage time length to ensure that m meets the following publicFormula (1).

m-1<T_out×R_c≤m (1)。

In the formula (1), T_out×R_cIndicates the planned energy storage duration, R_cIndicating the ratio of the energy storage time.

Wherein the first m-1 energy storage periods

The planned energy storage time of (a) is 1 hour,

representing the energy storage time of the ith energy storage period in the first m-1 energy storage periods,

the planned energy storage time of the time interval is T_out×R_c-m+1，

Indicating the planned energy storage duration in the mth energy storage period.

Sorting the time-sharing energy storage values (for example, the discharge prices of all the operation periods) of all the operation periods (one operation period is 1 hour, and 24 operation periods are totally arranged in 1 day) according to the sequence of the time-sharing energy storage values from low to high to obtain a second sorting result

Representing the timesharing stored value (charge price) during the ith operating period.

As an example, assume that the planned discharge duration T_outIs 1 hour, the preset energy storage time ratio R_cAt 0.5, the programmed energy storage duration can be calculated as 1 × 0.5 — 0.5 (hours). Moreover, the value range of m can be further determined to be more than or equal to 0.5 and less than 1.5 by the formula (1).

As an example, in practical applications, when the stored energy is equivalent to the discharge energy, the energy efficiency of the energy storage device may be maximized, so that after the discharge strategy under each planned discharge time duration is determined according to the above steps, the stored energy time duration and the corresponding stored energy may be set according to the discharge time duration and the corresponding discharge energy in the discharge strategy. For example, when the discharging periods are 0,1, 8, and 16, and the discharging amounts corresponding to the discharging periods are x1, x2, x3, and x4, respectively, then at least one energy storage period may be selected in order from low to high according to the second sorting result obtained above, and the energy storage amount of each energy storage period may be determined according to the discharging amounts of the discharging periods. Assuming that the operation period sequence in the second sorting result is [0(24),1,2,4,5,8,10,11,12,18,16,13,6,7,21,22,20,19,17,16,14,15,23,3], the planned energy storage duration is 0.5 hour, then the energy storage period may be 0 hour (the energy storage time is 0.5 hour), and the corresponding energy storage amount is x1, or the sum of x1, x2, x3 and x 4. The energy storage period may also be 2 hours (energy storage time of 7.5 minutes), corresponding to an energy storage of x1, and 4 hours (energy storage time of 7.5 minutes), corresponding to an energy storage of x2, 5 hours (energy storage time of 7.5 minutes), corresponding to an energy storage of x3, 8 hours (energy storage time of 7.5 minutes), corresponding to an energy storage of x 4.

It should be noted that, in order to ensure stable and reliable operation of the energy storage device, the energy release time period and the energy storage time period in the energy release strategy and the energy storage strategy cannot overlap.

As another example, the formula may also be based on

And calculating the energy storage corresponding to each energy storage time period.

In some embodiments, the capacity requirement determining module 104 includes:

and the energy storage requirement determining unit is configured to determine the energy storage capacity requirement of the energy storage device in the operation period according to the total energy storage amount and the total energy discharge amount.

As an example, assume that the sequence of the plurality of discharge periods in the discharge strategy determined according to the above steps is [1,2,4,8,18,24 ]]The sequence of the plurality of energy storage periods in the energy storage strategy is [3,16,17,22 ]]The overall charge and discharge condition after 24 hours of a day is recovered to [ 1]^out,2^out,3ⁱⁿ,4^out,5,6,7,8^out,9,10,11,12,13,14,15,16ⁱⁿ,17ⁱⁿ,18^out,19,20,21,22ⁱⁿ,23,24^out]. That is, the continuous energy storage period of the energy storage device is [3] within 1 day of the operation cycle],[16,17],[22]3 segments in total, and the continuous energy release time period is [24,1,2]],[4,8],[18]3 sections in total.

And determining the energy storage capacity requirement of the energy storage equipment in the operation period according to the total energy storage amount and the total energy release amount. Specifically, the energy storage capacity requirement of the energy storage device in the operation period can be determined according to the maximum value of the total energy storage amount and the total energy discharge amount, and is recorded as Q_realI.e. the energy storage capacity requirement for actually storing energy under ideal conditions.

In some embodiments, the system further includes:

Taking the electric energy storage device as an example, the value can be represented by' nominal voltage per cell + nominal capacityThe dischargeable depth, the capacity decay rate, and the charge-discharge efficiency were obtained.

As an example, the minimum number N of energy storage units required by the energy storage device in the operation cycle can be calculated according to the following formula (2).

N is Q_real÷Q_unitGet the actual total effective energy of stored energy as NxQ_unit。

In some embodiments, the scheme determining module 106 includes:
