Abstract
Industrial sector in each country consumes large amounts of total produced electrical energy. Hence, industrial customers with flexible loads are attractive targets for implementing demand-side management (DSM) programs. In recent years, Iranian energy ministry has applied an industrial operational reserve program (IORP) to reduce energy shortage during peak hours. This program has been developed to encourage industrial customers to participate in DSM programs, while steel plants show fewer tendencies to take part in these programs. In this paper, a techno-economic feasibility analysis of implementing IORP on steel plants, as the largest consumers of Iran’s industrial sector, is presented. For this purpose, first, the production process of a steel plant is modeled. Then, an optimization problem is developed to obtain the optimal scheduling of processes involved in producing steel through considering their technical and economic aspects. In order to solve the proposed problem which is mixed-integer nonlinear, Benders decomposition approach is used. Eventually, from the viewpoint of a steel plant owner, the profitability of taking part in IORP is investigated in three possible scenarios. The simulation results showed that steel plants can benefit from participating in IORP.
