Abstract

The invention belongs to the field of load aggregation and effective consumption of new energy, particularly relates to an energy efficiency optimization method based on a fine adjustment water heatertemperature set point, and mainly aims at the load of an electric water heater. Firstly, a decomposition model and a state sequence model of a single water heater load are established; and then, selecting an optimal combination meeting conditions in the model through an artificial immune algorithm. And finally, the weight coefficient of each component in the combination is calculated through a least square method, so that the total aggregated power output is closest to the target power curve, and the tracking of the target is realized. The comfort level of a user is fully considered, the modeof adjusting the temperature set point of the water heater is adopted, and energy efficiency optimization of clean energy is achieved through an artificial immune algorithm and a least square algorithm.

Description

technical field [0001] The invention belongs to the technical field of electric load identification, and in particular relates to an energy efficiency optimization method based on fine-tuning the temperature set point of a water heater. Background technique [0002] Clean energy has developed rapidly in recent years and is an important part of the future energy structure. However, with the increase of installed capacity, the problem of abandoning wind and solar is particularly prominent. The new version of the "Demand-side Management Measures" lists green power consumption as a new key work content, and promotes the consumption of clean energy power from the demand side. Among them, the water heater load can store electric energy in the form of heat energy, which is similar to the effect of batteries. After scientific cluster control, load resources can be equivalent to an energy storage system, which is an economically feasible method for clean energy consumption. With th...
