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.
