Aiming at the problem that modelling and prediction of conventional load do not consider user behavior characteristics and need to take massive historical data as the research basic

a modelling method of household energy consumption characteristics with the consideration of physical features and behavior factors is proposed. Taking the household energy center as the research object

the overall analysis flowchart is introduced

meanwhile the external demand

internal conversion and terminal energy load type are induced. Considering the physical features and behavior factors

the energy consumption model of electrical equipment is built and its expansion method is proposed. On this basis

the user energy consumption behavior is simulated with the combination of non-intrusive load decomposition and Markov chain. Case analysis shows that

the proposed method has the ability to depict load portrait curve independently and no longer depends on massive data for derivation drive.
