Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the drawings and examples.

[0025] Reference figure 1 , This method includes the following steps:

[0026] (1) First perform step 101, according to the household daily load curve statistics, the daily water consumption of a single water heater base=[6 4 3 3 1 5 13 48 33 36 27 26 23 23 24 15 17 16 24 32 26 17 23 24];

[0027] (2) Perform step 102, divide 1000 water heaters (total power 3600kw) into 10 groups according to power, capacity, upper and lower temperature limits and daily water consumption, respectively [55°C, 50°C, 120L, 3000W, 2 / 3*base], [55°C, 50°C,160L, 3000W, base],[55°C, 50°C, 200L, 3000W, 1.2*base], [55°C, 50°C, 320L, 3000W, 1.5*base], [55°C, 50°C, 320L, 6000W, 1.5*base],[50°C,45°C, 120L,3000W, 2 / 3*base], [50°C, 45°C, 160L, 3000W, base], [50°C, 45°C, 200L, 3000W,1.2*base], [50°C, 45°C, 320L, 3000W, 1.5*base], [50° C, 45°C, 320L, 6000W, 1.5*base];

[0028] (3) Perform step 103....

Abstract

The invention discloses a multi-scale direct load control method of an electric water heater group. The method comprises the following steps: generating single electric heater daily water data according to a family daily load curve, and setting multi-scale according to an electric power system daily load curve; and aggregating the electric water heater to form multiple water electric heater groups; and performing a quantum evolutionary algorithm on each scale of the water heater group to obtain an optimal control strategy. Through the adoption of the method disclosed by the invention, the peak-clipping and valley-filling can be effectively performed, and the method has important significance for the stability and the economy of the electrical power system.

Description

Technical field [0001] The invention relates to the direct load control optimization of an electric water heater group, and more specifically, it further realizes the optimized direct load control of the electric water heater group by introducing multiple scales. Background technique [0002] The continuous growth of power users makes the peak load demand of the power grid higher and higher, and it is not a reasonable solution to solve the peak load demand by continuously expanding the power system. Direct load control is based on this. By adjusting the corresponding load curve, part of the peak load is transferred to the off-peak period to achieve the effect of peak shaving and valley filling. The electric water heater group is the most common controllable direct load, and load transfer is realized by adjusting the heating method of the water heater. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned s...
