Description
Technical Field
The invention relates to the technical field of smart power grids, in particular to a calculation method and a system for interruptible load electricity price in power grid peak shaving.
Background
Grid peak shaving services play an increasingly important role in maintaining the real-time supply and demand balance of power systems. Strictly speaking, the peak shaver capacity is a part of the main electric energy market transaction, and the cost thereof is considered to be contained in the main electric energy selling price, so that the main electric energy selling price can be not compensated separately. However, if the peak shaving power required by the system has special requirements on the speed and the like of the unit and the cost and the non-peak shaving power cost are greatly different, the peak shaving power is classified as auxiliary service.
The interruptible load electricity price is an electricity price formulated in consideration of reliability factors, and is an electricity price other than the existing single electricity price, two electricity price, peak-valley time-of-use electricity price and seasonal electricity price. The interruptible load electricity price mainly means that when the system peak power supply is insufficient, the electricity user temporarily reduces or interrupts the electricity consumption in the electricity consumption peak period according to the agreement signed by the electric power department, thereby giving the user a certain compensation correspondingly.
Implementing interruptible load electricity prices is a major economic incentive in customer-side management.
The interruptible load electricity price can have positive influence on the operation and the management energy of the power grid enterprises: firstly, the power demand of the power industry in the peak period is reduced, and the peak regulation pressure of a power grid is relieved; secondly, the investment of a standby unit is saved, the safety, stability and economy of a power system are improved, and the reliability of power supply is improved; thirdly, because the interruptible load electricity price is attended by the user voluntarily, adverse social influence caused by power failure and electricity limitation can be reduced, and the customer satisfaction of the power grid enterprise is improved; and fourthly, the load can be reduced at any time, the running requirement of the power system can be flexibly adapted, and the load characteristic of the power grid can be improved.
For the power users, the power is interrupted in the power consumption peak period, and the suspended production is recovered in the off-peak period, so that the influence on the production and benefit of the enterprise is small, and meanwhile, the economic compensation of the interrupted load can be obtained, so that the method is quite economical and reasonable.
The existing interruptible load electricity price only considers the relation between the power failure loss and the interrupted electric quantity, and ignores the influence of other factors on the power failure loss, so that the calculated interruptible load electricity price is low in accuracy, and the execution of power grid peak shaving is influenced.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a calculation method of interruptible load electricity prices in power grid peak shaving according to an embodiment of the present invention, as shown in fig. 1, where the method includes:
s1, obtaining peak regulation capacity of a power distribution network and regulation rate of the power distribution network;
s2, acquiring a plurality of electricity-deficiency cost indexes of each interruptible load user based on the peak regulation capacity and the regulation rate, wherein for any interruptible load user, the plurality of electricity-deficiency cost indexes of any interruptible load user comprise at least two of interrupt electric quantity, power failure duration time, advance notification time and power failure time;
s3, obtaining an interruptible load electricity price corresponding to the interrupted electric quantity, an interruptible load electricity price corresponding to the power failure duration, an interruptible load electricity price corresponding to the early notification time and an interruptible load electricity price corresponding to the power failure moment according to an interruptible load electricity price model, wherein the interruptible load electricity price model represents the corresponding relation between each electricity deficiency cost index and the interruptible load electricity price;

The power system has peak regulation requirement when the power consumption is high, firstly, the peak regulation capacity of the power distribution network and the regulation rate of the power distribution network are obtained,
specifically, peak shaver capacity represents the difference between the total maximum adjustable output and the total minimum technical output of a peak shaver power plant in a power distribution network system.
Besides peak regulation capacity of the power distribution network, enough regulation rate is needed, and the regulation rate refers to the total regulation capacity of various units of the power distribution network in unit time, which needs to meet the requirements of load fluctuation and wind power output fluctuation on the regulation rate of the power distribution network.
On the premise that the peak shaving capacity and the peak shaving rate are determined, the peak shaving capacity and the peak shaving rate can influence the signing of the interruptible load contract in the electric power market environment, so that the realization of the peak shaving capacity can influence the interruptible load related index under the condition that the peak shaving rate constraint is met.
And then, on the premise of meeting the peak regulation capacity and the regulation rate, determining the electricity deficiency cost index of each interruptible load user, wherein the interruptible load user refers to a user who signs a related agreement with the electric power department and receives power failure in the peak electricity utilization period. Taking any one of the power-shortage cost indexes of the interruptible load users as an example for explanation, the power-shortage cost indexes of the interruptible load users comprise four aspects, namely: interruption of power, duration of power outage, advance notification time, and power outage time.
The interrupted power is the power saved by the user of the interruptible load during the power outage.
The power failure duration refers to the duration of power failure of the interruptible load user, and the longer the power failure duration of the interruptible load user is, the larger the total power failure cost is, but the power failure cost of different users is increased at different speeds along with the extension of the power failure duration.
The early notification time is an important factor affecting the loss of power failure because it gives a part of users the opportunity to adjust production so that it reduces a part of loss.
The power outage time refers to a time point when the user can interrupt the load specifically.
The embodiment of the invention examines the actual influence of the power failure on the interruptible load user from four aspects, and is more comprehensive and reasonable than the loss of the power failure on the interruptible load user only from the aspect of interrupting the electric quantity in the prior art.
After obtaining all the electricity deficiency cost indexes of the interruptible load user, processing each electricity deficiency cost index by the interruptible load electricity price model according to the interruptible load electricity price model to obtain an interruptible load electricity price corresponding to each electricity deficiency cost index, wherein the interruptible load electricity price refers to economic compensation given to the user by a power supply company in interruptible load management. In the case of an electric power system with insufficient power supply during peak electricity consumption, the consumers of electric power that can interrupt the load are temporarily reduced or interrupted during peak electricity consumption according to an agreement entered into the electric power sector, so as to promote the balance of power supply and demand during peak electricity consumption, thus giving such consumers a certain compensation accordingly.
Specifically, the interruption power is input into an interruptible load power price model to obtain an interruptible load power price corresponding to the interruption power, the power outage duration is input into the interruptible load power price model to obtain an interruptible load power price corresponding to the power outage duration, the advance notification time is input into the interruptible load power price model to obtain an interruptible load power price corresponding to the advance notification time, the power outage time is input into the interruptible load power price model to obtain an interruptible load power price corresponding to the power outage time.
Because the interruptible load electricity price corresponding to the interrupted electric quantity, the interruptible load electricity price corresponding to the power failure duration, the interruptible load electricity price corresponding to the early notification time and the interruptible load electricity price corresponding to the power failure moment are considered from the aspect of one electricity shortage cost index, in order to comprehensively consider the four electricity shortage cost indexes, a preset weight is set for the interruptible load electricity price corresponding to the interrupted electric quantity, the interruptible load electricity price corresponding to the power failure duration, the interruptible load electricity price corresponding to the early notification time and the interruptible load electricity price corresponding to the power failure moment according to the importance degree of the four indexes of the interrupted electric quantity, the power failure duration, the early notification time and the power failure moment, so that the interruptible load comprehensive electricity price of an interruptible load user is calculated.
According to the calculation method of the interruptible load electricity price in the power grid peak shaving, when the power distribution network is in a peak, peak shaving requirements of the power distribution network are determined, weights are distributed to the interruptible load electricity price corresponding to each power shortage cost index according to the importance degree of each power shortage cost index, and the interruptible load comprehensive electricity price of each interruptible load user is obtained, so that more interruptible load users are stimulated to participate in interruptible load agreement or contract signing, and the interruptible load capacity is increased, so that the purpose of participating in the peak shaving of more power grids is achieved.

wherein CI represents a consistency index, lambda max Represents the maximum feature root of the judgment matrix, and n represents the order of the judgment matrix.
The random consistency ratio is as follows:
wherein CR represents random consistency ratio, RI represents random consistency index values corresponding to different orders.
In the calculation process, if CR is less than 0.1, the judgment matrix is considered to have acceptable consistency, otherwise, the judgment matrix is adjusted until the judgment condition is met.
The consistency test is carried out on the index importance degree judgment matrix established by each power-shortage cost index of the interruptible load so as to truly reflect the relative importance degree of each factor, more reasonably and accurately measure the importance degree of each index and further determine the weight of each power-shortage cost index of the interruptible load.
On the basis of the above embodiment, preferably, the peak shaving capacity is obtained specifically by the following formula:
wherein PL represents the peak regulating capacity, and beta represents the peak Gu Chalv, P of the distribution network load t f Representing the maximum load of the target year omega G Representing the power supply unit set, omega r Represents the set, mu of the new energy unit with volatility i Representing the lowest guaranteed output coefficient of the ith unit, C i Indicating the capacity of the ith unit.
For the peak regulation capacity of the power distribution network, the factors of fluctuation and unstable new energy units of the load are mainly considered, and the peak regulation capacity mainly comprises the peak regulation capacity provided by an adjustable power unit and an energy storage unit, and the peak regulation demand generated by the fluctuation of the load and the peak regulation demand generated by the fluctuation new energy unit.

The power failure time is specifically determined by the following formula:
T＝ε 1i *ε 2i *ε 3i ，
wherein T represents the power failure time epsilon 1i Indicating the month, epsilon at which the power failure occurs 2i Indicating the date of the week at which the power failure occurred, ε 3i The time period of the date at which the power outage occurred is indicated.
For the moment of power failure 1i For the month, epsilon of the outage time of the interruptible user 2i Epsilon for the date of the week of the outage time of the interruptible user 3i If the power failure time is in the time period of the day, the influence of different power failure moments on the power failure moment of the user i is as follows:
T＝ε 1i *ε 2i *ε 3i
ε 1i 、ε 2i and epsilon 3i The power failure time is affected, and the power failure loss is also affected.
On the basis of the above embodiment, preferably, the interruptible load electricity price model is specifically as follows:
wherein X is i Represents any of the electricity deficiency cost indexes, P i (X i ) The interruptible load electricity price corresponding to any electricity deficiency cost index is represented,P 0 represents the basic electricity price, delta P i Indicating the change of electricity price, X 0 Representing the basic electricity price P 0 Corresponding to the basic average value of any electricity deficiency cost index, delta represents the electricity price coefficient and P 0min Indicating the lowest interruptible load electricity price.

The index module 202 determines the electricity-deficiency cost index of each interruptible load user on the premise of meeting the peak regulation capacity and the regulation rate, wherein the interruptible load user refers to a user who signs a related agreement with the electric power department and receives power failure in the peak electricity utilization period. Taking any one of the power-shortage cost indexes of the interruptible load users as an example for explanation, the power-shortage cost indexes of the interruptible load users comprise four aspects, namely: interruption of power, duration of power outage, advance notification time, and power outage time.
The model module 203 processes each electricity deficiency cost index according to the interruptible load electricity price model to obtain an interruptible load electricity price corresponding to each electricity deficiency cost index, wherein the interruptible load electricity price refers to economic compensation given to a user by a power supply company in interruptible load management. In the case of an electric power system with insufficient power supply during peak electricity consumption, the consumers of electric power that can interrupt the load are temporarily reduced or interrupted during peak electricity consumption according to an agreement entered into the electric power sector, so as to promote the balance of power supply and demand during peak electricity consumption, thus giving such consumers a certain compensation accordingly.
The comprehensive module 204 sets a preset weight for the interruptible load electricity price corresponding to the interrupted electric quantity, the interruptible load electricity price corresponding to the power cut duration, the interruptible load electricity price corresponding to the early notification time and the interruptible load electricity price corresponding to the power cut time according to the importance degrees of the four indexes of the interrupted electric quantity, the power cut duration, the early notification time and the power cut time, so as to calculate the interruptible load comprehensive electricity price of the interruptible load user.
The specific implementation process of the embodiment of the present system is the same as that of the embodiment of the method, and please refer to the embodiment of the method for details, which is not described herein again.
According to the calculation system for the interruptible load electricity price in the power grid peak shaving, when the power distribution network is in a peak, peak shaving requirements of the power distribution network are determined, weights are distributed to the interruptible load electricity price corresponding to each power shortage cost index according to the importance degree of each power shortage cost index, and the interruptible load comprehensive electricity price of each interruptible load user is obtained, so that more interruptible load users are stimulated to participate in interruptible load agreement or contract signing, and the interruptible load capacity is increased, so that the purpose of participating in the peak shaving of more power grids is achieved.
