  7. Abstract:
  8. The population growth and scarcity of resources such as water and land make the food security as one the most important critical priorities in the world. Development of food production in greenhousesinstead of the traditional agriculture in rural areas is an efficient and applicable approache to reach food security and optimum use of water resources. However, this requires more capital. An important part of this cost is related to the cost of energy supply for heating and cooling in order to provide a suitable condition for the growth of plants. Optimal design of a rural energy supply and optimal operation of existing greenhouses to maximize the benefit of the greenhouse owners and to decrease the living costs in rural areas I will help to construct new greenhouses. In this study, the aim is to propose a comprehensive method for designing energy supply system to optimize energy consumption of a rural area including greenhouses based on the energy hub concept. For this aim, energy consumption in a greenhouse is modeled with temperature and humidity control constraints and then the greenhouse energy model, which is intrinsically non-linear, is linearized. Based on this linearized model, the proposed optimal energy supply system design problem is a unique optimization problem in which not only the design variables are determined but also the variables related to the optimal operation of the greenhouse as well as the variables related to the optimal flexible domestic energy consumption are determined in a unique optimization method in order to minimize the energy consumption. The results show significant decrease in cost, that is up to 10% with the international tariffs and more saving would be possible considering the current national’s tariffs. Moreover, the results demonstrate that the results of the linear and non-linear models are in good agreement with less than 1% difference
