In this paper, it is claimed that a Demand Response (DR) program, appealing to smaller users, is economically advantageous for an aggregator engaging in both types of wholesale market This is obtained by formulating a profit maximization model of a DR aggregator, which includes consumers linked through direct and indirect control contracts. The conclusions are supported by simulations of different market price scenarios, considering consumer decision-making behavior. The development of the DR aggregator management model includes the interaction with three different instances, two of them corresponding to the wholesale electricity market, in addition to its interaction with consumers, through a portfolio of different contracts.The model corresponds to the solution of a bi-level optimization problem.This work combines various contract types into a single management model, including indirect control contracts where the management of the aggregator depends on consumer behavior.
