Abstract

The invention discloses a household user short-term load prediction method based on a load decomposition technology, which relates to the technical field of power data decomposition and detection, through a non-intrusive power load monitoring technology, power utilization equipment of a household user can be classified, the load power utilization equipment is selected, the power utilization equipment is decomposed, and the running state of the power utilization equipment is obtained; an operation state of the electric equipment is converted into data information, the operation state of the electric equipment is converted into the data information, and the data information and the original load time sequence are input into an immune neuron for training so as to acquire an electric quantityvalue used by the electric equipment at a certain moment in the future, thereby the electricity consumption of the household equipment is predicted. The method can guarantee that the prediction erroris within an acceptable range, and enables the improvement of the prediction performance to be more feasible and cost-effective.

Description

technical field [0001] The invention relates to the technical field of power data decomposition and detection, in particular to a short-term load forecasting method for household users based on load decomposition technology. Background technique [0002] Non-intrusive power load monitoring technology is a brand-new power load information collection and analysis technology. This technology can know the power consumption status information and power consumption law of each or each type of electrical equipment inside the total load through the measurement and real-time analysis of the single-point total amount of electrical information of the power load, without the need of traditional monitoring technology Each interested electrical equipment is equipped with a sensor with digital communication function. Only by measuring and analyzing the voltage, current and power information at the entrance of the electrical load, the real-time power of different electrical equipment inside...
