Dynamic Electricity Demand Prediction for UK Households

The nature of domestic electricity load is highly dependent on the demand of occupants. Domestic energy use, especially for electricity, is not only based on residents activities, also related with the type of electrical appliances and weather conditions. To manage and optimise electricity generation and the effective use of energy storage, it is important to be able to accurately predict electricity demand. This paper presents high-resolution real load energy data for three UK dwellings throughout the year. Seasonal models have been produced for each dwelling and the use of electrical appliances at certain times are analysed to predict the number of active occupants. The possibility of active occupancy at each thirty seconds is generated stochastically by Markov-Chain technique and Markov-Chain Monte Carlo method is used to predict the active occupant profiles and the related electricity demand dynamically. The methodology can be used for any other domestic dwelling type to generate corresponding active occupant profile. The predicted electricity profile can be used for effective demand side management.
