01 Optimum planning and scheduling of a water-energy of a greenhouse in different climate conditions in Iran

This study aims to optimize the energy supply system of a greenhouse considering twelve different climate conditions in Iran. For this purpose, an integrated two-objective linear energy optimization model has been developed to control the inside temperature and provide the required heating, cooling, and electricity by receiving electricity, gas, and water. The mentioned goals are to minimize operating costs (taking into account the discount rate over twenty years) and the initial cost and minimize the deviation of the inside temperature from the desired value. The initial cost of energy equipment is the result of examining data from domestic manufacturers and obtaining the equipment cost curve. The analysis of the results shows that the best areas for greenhouses construction are Kerman, Tehran, and Arak, respectively, for which the total cost is around ten thousand dollars.
