In this paper, a detailed modeling of energy consumption in the processes of producing aluminum and cement industrial units based on the linear piece-wise approximation (LPWA) method is presented. The presented model has been implemented in the day-ahead energy management planning of a microgrid including these industrial units. In order to increase the profit of the mentioned industrial units, the demand response programs are implemented and therefore these units are able to participate in the energy and ancillary services market. The energy management planning proposed in this paper, considers the exact model and all constraints of the industrial units and microgrid in order to maximize the profit of the microgrid and these units. The performance of the model and the proposed planning has been evaluated through two case studies, with and without implementation of demand response programs. In addition, the effect of the changes in the profit obtained by selling the product of each industrial unit and the prices of sold energy by microgrid to the electricity market, on the profit of the units and the microgrid, have been examined using the sensitivity analysis. The obtained results, besides validating the proposed model, show that the implementation of demand response programs and the participation of industrial units in the energy and ancillary services market, not only modifying the demand curve but also increase the profit of the microgrid and units.
