摘要：In order to meet varied requirements of gas and electricity in petrochemical enterprises, as well as reducing the operation cost and minimizing energy use, optimal operation of steam power systems is a must. Based on previous work, this research proposes a mixed integral non-linear planning model (MILNP), which accounts for expenses of operation, maintenance, depreciation, and changeover cost in between startup and shutdown stage. The model is validated against operative data. The results show optimal control strategy can be quickly obtained with improved PSO algorithm, accompanied with considerable cost saving.
