Problems solved by technology

[0006] At present, enterprise users lack reasonable and scientific methods for setting and controlling the maximum demand of electricity, especially when controlling, they cannot provide accurate data support, and the production and scientific, orderly, and economical power consumption are not affected. It is often impossible to balance the two aspects

Embodiment Construction

[0032] refer to figure 1 , a kind of electric power demand control method based on mathematical model that the present invention proposes, comprises:

[0033] Establish a load control model, and conduct real-time online monitoring of the selected electrical equipment and enterprise power supply gateway loads, and substitute the monitoring data into the load control model to determine the direction of load increase or decrease.

[0034] The load regulation model is:

[0035]

[0036] Among them, P D,i is the electricity demand at the current moment, kWh G,i Indicates the electric energy at the current moment, kWh G,i-a for the time period t 0 The previous electric energy indication, a is the time period t 0 Inner data times, t is the data collection interval, T 0 For the calculation cycle, T in this embodiment 0 Equal to 3600; GDI is the demand index beyond agreement, P G,i for the time period t 0 The enterprise power supply gateway load P collected for the ith time...

Abstract

The invention provides a power demand control method based on a mathematical model, which comprises the following steps of: establishing a load control model, carrying out real-time on-line monitoringon the selected electric equipment and the power supply gateway load of an enterprise, and substituting the monitoring data into the load control model to judge the load increasing or decreasing direction. The invention provides a power demand control method based on a mathematical model, By constructing mathematical model to provide accurate power demand control data for enterprises, reasonableand scientific adjustment of the maximum power demand setting of enterprises, according to specific data support accurate control of power demand, so as to achieve safe production and scientific, orderly power consumption, and conducive to avoid power waste as far as possible, in order to save electricity.

Description

technical field [0001] The invention relates to the technical field of power demand side management, in particular to a mathematical model-based power demand control method. Background technique [0002] The maximum demand (Maximum demand, abbreviated as MD), that is, the agreed demand, refers to the maximum value of the average load of electricity per unit time (usually 15 minutes) of the power user within an electricity bill settlement cycle (usually refers to one month) . The maximum demand management directly reflects the power management level of the enterprise. The greater the gap between the actual power load and the agreed demand, the higher the cost of power consumption. If the demand is lower than the agreement, the excess part of the basic electricity fee will be paid more, and if the demand is higher than the agreement, the higher part will be doubled. The maximum demand is directly related to the electricity bill of the power user. Controlling the maximum dema...
