Abstract

 

Electric utilities frequently use remote load control programmes to improve their network operating conditions. Ordinary economic objectives are loss reduction and peak demand limiting, physically constrained by equipment’s thermal stress limits. Loads chosen for shedding actions are those providing a service not negatively affected by temporary supply interruptions. Typical examples in the residential sector are air-conditioning and water heating.

This communication describes a decision support model to cope with the main utilities’ concerns towards remote load control: minimise peak demand, maximise return and provide the maximum possible quality of the service to customers. The model aims at the selection of the best load shedding strategies to be applied to a forecast daily load diagram.
