This work describes a method to coordinate the residential equipments management for optimising the load curve on rural electric power systems in terms of peak load reduction. The residential electric heating can be modelled mathematically. A “bi-objective” optimisation method can mitigate between cost and comfort while respecting fixed constraints. The flexibility of this equipment can be exploited to smooth the load curve by shifting its consumption during off-peak periods. This present approach consists in optimizing electric heating consumption that takes into account estimated load curve consisted by other domestic equipments and customer temperature comfort. A statistical evaluation will be made to quantify the profit in term of peak reduction when consumption of the other equipments is randomly generated.
