Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with accompanying drawings and examples.

[0025] refer to figure 1 , this method includes the following steps:

[0026] (1) First execute step 101. According to the household daily load curve statistics, the daily water consumption of a single water heater base=[6 43 3 1 5 13 48 33 36 27 26 23 23 24 15 17 16 24 32 26 17 23 24];

[0027] (2) Execute step 102, divide 1000 water heaters (total power 3600kw) into 10 groups according to power, capacity, upper and lower limits of temperature and daily water consumption, which are [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];

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 optimization of the direct load control of the electric water heater group, more specifically, it further realizes the optimized direct load control of the electric water heater group by introducing multi-scale. 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. The direct load control is based on this, and by adjusting the corresponding load curve, part of the peak load is transferred to the off-peak period, so as to achieve the effect of peak shaving and valley filling. The electric water heater group is the most common controllable direct load, and the load transfer is realized by adjusting the heating mode of the water heater. Contents of the invention [0003] The technical problem to be solved by the present invention is to over...
