Description

Peak clipping and valley filling linkage demand response method and device based on industrial enterprise resource pool
Technical Field
The invention relates to a peak clipping and valley filling linkage demand response method and device based on an industrial enterprise resource pool, and belongs to the technical field of power demand side management.
Background
The electric power system is the key element of the whole national energy strategy and is the life line of national economy. With the continuous improvement of the modernization degree of national economy, seasonal and time-interval loads are rapidly increased, the peak load of a power grid is continuously increased, the peak-valley difference of the power grid shows a gradual expansion trend, the imbalance contradiction of power supply and demand in partial areas is serious, and the safe and stable operation of a power system is seriously influenced. The traditional method of increasing the installed capacity of the power grid by simply relying on the increase of the installed capacity of the power grid to passively meet the peak load demand of the power grid causes huge pressure on investment of power generation, power transmission and transformation and power distribution construction, and simultaneously causes low utilization efficiency of power grid facilities. Therefore, the method for adjusting the operation balance capability of the power grid, which is feasible, economical, efficient and environment-friendly, is urgently sought.
At present, domestic and foreign researches and practices prove that automatic demand response is implemented, and power demand side resources are mobilized to participate in power grid operation, so that the contradiction between power supply and demand can be effectively relieved, the reliability of a power system is improved, the investment pressure of power grid facilities is relieved, and the energy utilization rate and the consumption of primary energy can be reduced. The automatic demand response has abundant objects (power demand side resources), and not only comprises various loads such as illumination, air conditioners, motors and electric heating, but also comprises various energy storage devices such as cold accumulation, heat accumulation and electric power storage, and also comprises a distributed power supply, an electric automobile and other energy replacement devices. Demand response practices in developed countries such as the United states, canada, british and the like show that by adopting effective incentive mechanisms and technical measures, users on the power demand side can optimize the power utilization mode of the users, reasonable allocation and efficient utilization of resources on the demand side are promoted, peak-valley difference of a power grid is effectively improved, and power supply and demand balance capacity is improved. Demand response is essentially to facilitate power supply and demand balance through grid interaction with users, and grid companies start with massive customer-side load resources and deeply mine customer-side adjustable resource potential. A practical adjustable load participation power grid adjusting mechanism is formed by analyzing and researching feasible modes, technical routes and economic benefits of various loads participating in power grid interaction.
The demand response peak regulation load means that the power utilization time of various users can be reasonably and programmatically arranged and organized according to the power utilization rules of different users so as to reduce the peak of a power grid and fill the load of a valley. The demand response resource participating in the peak shaving of the power system has 2 characteristics: the load (monomer or polymerization) capacity is relatively large, and the controllability is large; on the premise of no influence on the specified flow, the power utilization curve can be translated at different periods by adjusting production planning and personnel working schedule, and industrial production is carried out at the power utilization trough period.
Therefore, in the process of organizing demand responses by grid companies and government departments, the goals can be summarized as: firstly, how to better respond to the user is ensured, and the response capability is improved. Belonging to the problem of project management and incentive mechanism. Secondly, how to ensure that the demand response result is flexible and reliable, the power load curve shows the expected effect, and the demand response organizer needs to perfect on the aspect of service design.
In the prior art, the demand response service mainly adopts an invitation mode, and the result of the participation of the user in responding to the invitation cannot be accurately controlled. After the demand response peak clipping event, part of the industrial enterprise users participating in the peak clipping event adjust the time beyond the offer time due to the limitations of the production operation. When the capacity beyond the offer is too large, the grid load curve drops beyond expectations. At the moment, the power grid dispatching department needs to lift the load curve, and if no plan is made in advance, the risk is difficult to control.
In summary, the flexibility and reliability of demand response are the key to demand response implementation and popularization, and the problem that how to improve the flexibility and reliability of demand response is currently solved is that a pure demand response peak clipping event has a risk of excessive regulation and control.

Detailed Description
The present invention will be further described with reference to the following examples.
A peak clipping and valley filling linkage demand response method based on an industrial enterprise resource pool is disclosed, as shown in figure 1, an execution main body comprises a power dispatching department, a demand response organizer and a demand response user, the power dispatching department provides load regulation and control demands to the demand response organizer, the demand response organizer issues demand response offer information to the demand response user, the demand response user adjusts production operation electric equipment to respond, and a government department carries out supervision on the demand response organizer. The method specifically comprises the following steps, as shown in fig. 2:
and (A) the power dispatching department provides a demand response peak clipping demand to a demand response organizer according to the load shortage condition of the power grid operation, and the demand response organizer selects a demand response user according to the adjustable load resource pool and informs the demand response user of peak clipping event invitation information. The peak clipping event offer information comprises: a peak clipping response period and a peak clipping response capacity;
the adjustable load resource pool is established in advance by a demand response organizer, the file information of demand response users in the adjustable load resource pool is maintained in daily work, and the load adjustment characteristic of the demand response users is mastered. The load regulation characteristic includes: a responsive period, a responsive type (peak clipping/valley filling), a responsive capacity, a response duration, a response ramp-up time (a time interval from the start of the response to the arrival of the response), and the like.
When the power dispatching department provides a demand response peak clipping demand, the demand response organizer issues peak clipping event offer information through a related information channel.
And (B) feeding back the peak clipping participation information through a related information channel after the demand response user receives the peak clipping event invitation information.
The related information channels include: short messages, telephones, web pages, mobile phone APP and a demand response terminal.
The peak clipping participation information fed back by the demand response user comprises the following steps: whether to participate in peak clipping, participate in response periods, plan to curtail power, associate response periods, associate curtailed power.
The associated response period is a response period that exceeds an offer target demand.
The associated curtailed power is a responsive power that exceeds the invited target demand.
And (C) according to peak clipping participation information reported by the demand response user, whether peak clipping, participation response time period, planned reduction power, associated response time period and associated reduction power are participated, the total reducible power of the demand response user in the peak clipping response time period required by peak clipping and the total associated reduction power in the associated response time period are calculated, the peak clipping event invitation response effect is evaluated according to the total reducible power, a demand response organizer judges the degree of excessive peak clipping according to the peak clipping event invitation response effect and the total associated reduction power, a power grid operation load curve after the peak clipping event is estimated, whether valley filling linkage response is required is judged, if valley filling is required, the step D is carried out, and if valley filling is not required, the step G is carried out.
The reason for the association response is: the demand response of partial peak clipping only adjusts in the response period of the offer, but the response period of partial user exceeding the offer due to the operation limit adjusting time exists, so the feedback of the associated response period and the associated clipping power is needed. When the capacity exceeding the peak clipping offer is too large, the power grid load curve has deviation, and the valley filling response linkage is carried out for a short time immediately after the peak clipping response. The valley filling response capacity and the valley filling response period fed back by the valley filling user make up the load difference.
And (D) if valley filling linkage response is needed, formulating a linked valley filling event plan according to the associated response pre-evaluation result, and sending the valley filling event plan to a demand response user who does not participate in the peak clipping event in the adjustable load resource pool.

The valley filling participation information includes: whether to participate in a valley fill, a participation response period, a scheduled boost power, an associated response period, an associated boost power.
The demand response users participating in the peak clipping event and the valley filling event need to be different demand response users, and according to the normal process, the demand response users participating in the peak clipping response have the demand of timely recovering normal power utilization after the response is finished, so that the situation that the same user participates in the valley filling event after participating in the peak clipping event is unreasonable.
And (F) making a valley filling execution plan according to the valley filling participation information fed back by the demand response user.
The valley filling execution plan includes: the user details of the participation in the valley filling response, and the valley filling response capacity and the valley filling response period of each user.
Step (G), if the valley filling is not needed, only sending down a peak clipping execution plan; if the valley is required to be filled, simultaneously issuing a peak clipping execution plan and a valley filling execution plan; under the condition of only issuing a peak clipping execution plan, a demand response user executes the peak clipping execution plan according to the issued demand response time interval requirement and the issued response quantity requirement; and under the condition of simultaneously issuing a peak clipping execution plan and a valley filling execution plan, a demand response user participating in peak clipping and valley filling respectively executes the peak clipping execution plan and the valley filling execution plan according to the response time period of peak clipping and valley filling and the response quantity requirements of peak clipping and valley filling.
The peak clipping execution plan comprises: the user details participating in the peak clipping response, and the peak clipping response capacity and the peak clipping response period of each user.
The peak clipping execution plan and the valley filling execution plan are preferably issued simultaneously. Because the user needs to prepare in advance when participating in the peak clipping event or the valley filling event, and arranges production and scheduling staff in advance, the events are preferably issued at the same time. The general principle is that if the load shortage needs to be filled after the peak clipping event is ended, the load of filling the valley can be quickly supplemented.
And (H) carrying out peak clipping event result evaluation and valley filling event result evaluation according to the execution conditions of the peak clipping execution plan and the valley filling execution plan, and carrying out peak clipping and valley filling linkage comprehensive evaluation.
Evaluation of the result of the peak clipping event: evaluating whether the actual peak clipping response quantity of the demand response user is consistent with the target peak clipping response quantity or not and whether the actual peak clipping response time period is consistent with the target peak clipping time period or not; and evaluating the difference between the overall peak clipping response curve (the peak clipping response quantity and the peak clipping response time period) of the peak clipping event and the target peak clipping curve.
And evaluating the grain filling event result: evaluating whether the actual valley filling response quantity of the demand response user is consistent with the target valley filling response quantity or not and whether the actual valley filling response time period is consistent with the target valley filling time period or not; and evaluating the gap between the overall valley filling response curve (the valley filling response quantity and the valley filling response period) of the current valley filling event and the target valley filling curve.
Peak clipping and valley filling linkage comprehensive evaluation: the demand response system main station evaluates the linkage comprehensive effect after executing the peak clipping execution plan and the valley filling execution plan to obtain an evaluation index, wherein the evaluation index comprises: actual peak clipping amount, actual valley filling amount, peak clipping and valley filling linkage connection time, load curve condition and deviation between reported capacity and actual execution capacity of demand response users participating in events.
In order to realize the above contents, the method comprises a user response time interval and response quantity statistical analysis function, a peak clipping event plan and linked valley filling event plan making function, a peak clipping event and valley filling event linked monitoring function, a peak clipping and valley filling linked comprehensive evaluation function and the like.
According to the peak clipping and valley filling linkage demand response method based on the industrial enterprise resource pool, a specific implementation case is introduced,
the method comprises the following steps: the dispatching department of a certain network power-saving company issues peak clipping requirements according to load prediction results, and the next day is 10: peak clipping is 5000kW during the period of 00-11.
Step two: the demand response organizer (such as the network province company marketing department) issues the peak clipping and valley filling linkage offer information in turn, and the demand response user feeds back information, as shown in table 1:
TABLE 1 electric power consumer demand response feedback data sheet
Figure 336296DEST_PATH_IMAGE002
Description of the drawings: 1. for the power consumers including the house numbers "3201001", "3201002", "3201003", "3201004", peak clipping events are issued, assuming that only four houses feed back the situation, as shown in the table, "3201004" does not participate, "3201001" and "3201003" normally participate, "3201002" exceeds the participation time, the association response period is "12-00 — 13", and the association response capacity is 1200kW. If other users can choose to avoid the correlation response when the peak clipping plan is made. But if only these three users are willing to participate in the response at this time and cannot avoid the association response, the dispatching department can only accept these three users to participate in the response, thereby bringing a load valley filling requirement of 1200kW of 12-13.
2. After a linkage valley filling response requirement exists, a valley filling event is issued for power users including the user numbers "3201005", "3201006", "3201007" and "3201008", and it is assumed that only three users are willing to participate, wherein "3201005" normally responds to 1200kW, and "3201007" responds to 1200kW, but there are cases of association response, and "3201008" normally responds, but only 600 kW. At this time, when a valley filling plan is made, the event is preferably selected to be issued by '3201005'.
Step three: and formulating a peak clipping and valley filling plan according to the information fed back by the user, and simultaneously issuing an event.
Step four: and after receiving the event, the power consumer executes the event according to a plan.
Step five: and evaluating according to the execution condition of the user. The evaluation indexes can comprise actual peak clipping amount, actual valley filling amount, peak clipping and valley filling linkage connection time, load curve condition, deviation between user reporting capacity and actual execution capacity of participating events and the like.
Therefore, the risk of uncertainty of user response is reduced through peak clipping and valley filling linkage, the margin of elastic adjustment of a load curve is increased, and the safe and stable operation of a power grid is guaranteed.
