Embodiment Construction
[0090] In order to clarify the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0091] refer to figure 1 In one embodiment shown, the overall process steps of the method of this embodiment are as follows:
[0092] 1) Based on the analysis of multiple time scales and load interruption priority, formulate a rolling control strategy for large industrial loads to participate in power grid peak regulation;
[0093] 2) Obtain the historical data of the electricity load of each industrial user participating in peak shaving in the past month;
[0094] 3) Preprocess the original historical data of electricity load, fill in missing values, and remove noise values;
[0095] 4) If the data preprocessing is successful, go to step 5) and proceed to the next step, otherwise go to step 2) to reacquire the historical load data;
[0096] 5) Build the GRU neural networ...

The invention discloses a method for flexible regulation and control of large industrial loads in consideration of interruption priority. peak rolling control strategy; establish a two-way peak shaving optimization model; obtain real-time load data, interruption characteristics, and properties of thermal power units, and select an appropriate two-way peak shaving optimization model; obtain load forecast data; use multi-objective intelligent optimization algorithms to solve this complex problem Constrained multi-objective optimization model; formulate peak-shaving control schemes for large industrial loads and thermal power units. The present invention fully considers the economy and peak-shaving effect of the power generation side and the demand side participating in the peak-shaving of the power grid, and takes into account the difference in the interruptible capacity of different large industrial loads, and prioritizes the load with a higher interrupt priority to formulate the optimal The peak-shaving control scheme for large industrial loads and thermal power units has strong engineering practicability and promotion value.
Description
technical field [0001] The invention belongs to the technical field of power demand side management, and in particular relates to a method for flexible regulation and control of large industrial loads taking into account interruption priorities. Background technique [0002] With the rapid development of social economy, the rapid upgrading of industrial structure, and the continuous improvement of people's living standards, the demand for power supply from all walks of life in society has long been different from what it used to be. The contradiction between supply and demand has become increasingly prominent, which has greatly increased the risk and cost of power grid operation. In view of the current power consumption situation, traditional methods such as load rigidity adjustment and simple cutting can no longer meet the needs of intelligent power consumption, so the research on power demand side management technology is extremely important. [0003] In the research on po...
