Distinct approaches to model electricity consumers for the participation in demand response programs

Demand response can to be used in order to reduce energy consumption or, in an economic standpoint, to avoid the need of more expensive energy resources. The present paper proposes a methodology that makes possible to compare the modeling of distinct demand response programs by having different consumer remuneration approaches. The methodology, which is developed in the scope of a Virtual Power Players operation of a network, concerning its consumption reduction needs and the schedule of demand resources according to its price. The consumers are modeled as several approaches, namely, Constant, Elasticity, Linear, Quadratic and Steps. Several consumption reduction levels and economic evaluation scenarios have been implemented in a case study composed by 218 consumers and 4 suppliers from the main upstream network.
