Structural modelling of energy demand in the residential sector: 1. Development of structural models

We present the development of structural models for energy consumption in the residential sector. Customers were segmented into four main categories with six sub-groups within each category. A survey of over 100 customers provided data on the 17 appliances considered, which are grouped into three main categories. The models provide energy-use patterns for each category of customers for selected customer samples or for a chosen area. Energy patterns are simulated in 15-min time intervals. These show total demand and provide information on the structure of energy consumption in simulations for demand-management programs, long-term forecasting and customer identification.
