The influence of the consumer modelling approach in demand response programs implementation

The use of demand response programs brings several advantages to the power systems operators, to the consumers, as well as to the proper functioning of the whole electrical power system. The present paper proposes a methodology based on the use of five types of demand response programs (Steps, Quadratic, Constant, Linear and Elasticity). These programs corresponds to distinct approaches to model the consumer participation in demand response programs. This methodology can be used by a Virtual Power Player that aggregates and manages the small size consumers demand response for the participation in demand response programs. Distinct consumption reduction levels have been implemented in a case study composed by 218 consumers. The aggregator becomes able to discuss on the remuneration approach adequate for each reduction level and consumer type.
