It may also simply refuse to participate in demand response because it is unable to judge how to make production scheduling to be considered a successful response

[0005] Participating in demand response based on production scheduling based on experience, it is very likely that incorrect equipment power estimation, real-time load fluctuations, and abnormal load baselines caused by abnormal power consumption in historical daily load curves may lead to response failures and users cannot receive subsidies , which has a negative impact on user participation in demand response

[0006] For factories to completely stop production and participate in demand response, in addition to the possibility of invalid responses due to abnormal baseline data, it is more likely that the average response load is greater than 120% of the declared ...

Abstract

The invention discloses an information processing method and system for improving power consumer demand response effectiveness, and belongs to the technical field of power demand response data processing. According to an existing scheme, a user cannot visually see related data of demand response effectiveness, identification and rapid judgment cannot be conveniently carried out, and active participation of the power user in power demand response is hindered. According to the information processing method for improving the real-time demand response effectiveness of the power consumer, a real-time load curve is compared with a load base line according to a time sequence and drawn on the same interface for real-time display, and a real-time comparison graph is formed; meanwhile, a plurality of reference lines are additionally arranged in the real-time comparison graph, an adjustment scale is given, and data support is provided for production management of power consumers; and during the whole demand response period, the change of the load is tracked in real time, and a production manager is helped to accurately control the production load in an ideal interval.

Example Embodiment

[0100] One application of the present invention, specific embodiments:

[0101] Installation of user interaction in the user equipment production office manager, a device with display, as users understand the demand response target, dynamic changes of baseline data load and the actual load enterprise information window.

[0102] Demand response terminal is connected meter device via infrared communication port meter high pass frequency table or by collecting data for all branch circuit loads under the fieldbus interface mark acquisition table, the acquisition frequency can be set to 10-1 seconds if necessary, and real-time the resulting company will be collected total operating load the data forwarded to the user interaction devices to meet the needs of production managers to monitor real-time plant load.

[0103] (I.e., non-demand response period) in response to demand by the terminal side real-time requirements in the system management platform leisure baseline data downloaded user load or demand response in the demand response load baseline data downloading period when the event occurs, and forwarded to the user interaction device .

[0104] User interaction device according to the present invention process data Example:

[0105] During demand response, according to the demand response data transmission terminal, the terminal user interaction trended FIG load follow temporal changes on the display screen, such as figure 1 Shown, wherein the abscissa is the time value, from 0:00 to 0:00 the next day, the coordinates interval adjust the zoom, the vertical axis and values of the active power (kW).

[0106] A curve drawn business day electricity load profile data, P R1 , P R2 , P R3...... P Rn And to add new data points in real-time PRn+1 Continuously extend the load curve.

[0107] At the same time, the load baseline P in the day is drawn at the crude line B. B1 , P B2 , P B3... p B96. The interface is set up a vertical timeline, which can be moved left and right, the vertical timeline and the real-time load curve, the intersection of the load baseline, display the current load value P on should time points, respectively. R , Baseline load value P B.

[0108] User interactive device data processing embodiment during demand response of the present invention:

[0109] Demand Response Terminal Receives Signals (Regulatory Indicator P) V , Demand response periods) and the baseline data forward to the user interactive device, the user interactive device will respond to the event time, the response type (the peak or fill the field), the regulatory indicator, the response time period data is displayed on the interface.

[0110] The user interaction terminal changes the interface base color of the display interface to a deeper color based on the response time period information, to highlight the range of time. At the same time, a line segment is plotted in the demand response period, and the ordinate of the line segment is Where P Bx Load baseline data corresponding to the demand response time period, P B(x+n) For the load baseline data corresponding to the time point of the demand response period, N + 1 is the number of all load baseline data points in the entire demand response period (including the start and end time). P B(AVG) Baseline P B The average value of all the data in the demand response period, that is, the baseline average load for evaluating the demand response effect.

[0111] User interactive terminal according to P B(AVG) And regulatory indicator P V Calculate the average load P for the ideal satisfaction effect evaluation O(AVG) , P O(AVG) = P B(AVG) -P V.

[0112] Further, in the demand response period on the display interface, three horizontal line segments are drawn in dashed line C, the ordinate value of the line segment is P O(AVG) Bible, 80% P V P O(AVG) Upper limit and 120% P V P O(AVG) The lower limit value.

[0113] By showing the specific indicators and demand response time period information to the power user production management responsible, the company successfully participates in the scope of the target average load of demand response (ie 80% and 120%) P V The target average load is included in the operating load interval), which allows the person in charge of the production management to clearly understand which level is to reduce the requirements of the demand response effect evaluation index.

[0114] The user's interactive device continues to draw the actual load P in the same day R The data curve helps the manufacturer of production management understand the level of the current enterprise actual load, and the deviation size of the target average load. With P R The data curve enters the demand response period, and the user's interactive device starts calculating the demand response period P R Average, that is, the actual average load P R(AVG).

[0115] P R(AVG) (P) R(t1) + P R(t2) + P R(t3) + ... + P R(tn) ) / n, where T1 begins at the time of the demand response period, P R(t1) That is, the time collected to the actual load data is collected, TN is the moment when the actual load data is acquired in the last time, P R(tn) That is, the actual load data collected in the time period.

[0116] During the demand response, the horizontal line segment of the actual average load is continuously drawn on the interface of the user's interactive device, and the ordinate of the line segment will follow P R(AVG) Value changes fluctuate until the end of the entire demand response period, P R(AVG) The value is no longer changed, and the ordinate position of the line segment is constant.

[0117] The person in charge of the production management can actually average load on the interface P R(AVG) Relative target average load P O(AVG) The location can be judged whether the response of this demand is successful.

[0118] Those skilled in the art will appreciate that embodiments of the present application can be provided as a method, system, or computer program product. Therefore, the present application may employ a full hardware embodiment, a fully software embodiment, or in the form of a combination of software and hardware embodiments. Moreover, the present application may employ a computer program product that includes a computer available storage medium (including, but not limited to, disk memory, CD-ROM, optical memory, etc.) in one or more computers.
