A Stochastic Optimization Model for Gas Sale Company

A new stochastic optimisation model to assist companies dealing with gas retail commercialisation is described. Stochasticity is due to the dependence of consumptions on temperature uncertainty. Two different models for modelling temperature scenarios are compared. The model can be classified as an NLP mixed integer model, with the profit function depending on the number of contracts with the final consumers, the tipology of such consumers and the cost supported to meet the final demand and constraints related to a maximum daily gas consumption, to yearly maximum and minimum comsumption in order to avoid penalties and to consumption profiles.
