Abstract
This paper presents analyses of the model for the optimum design of standalone hybrid microgrid. The model is
developed with the aim of optimizing system component sizing that can reliably satisfy isolated loads. The objective function
is to minimize the annual cost of the plant while taking all constraints into consideration. Mixed integer linear programming
technique is used to solve the optimization problem. By applying some approximations, the output power of the wind energy
conversion system is expressed as a linear function of wind speed. Effects of different PV technologies and the rated power of
each unit have been investigated. The results have shown the ability of the proposed model by reducing the cost of energy by
89.35%, 90.26%, 88.3530%, and 89.99% for AP120, ASE 300, KC120 and SAPC165 respectively. In the same way the carbon
dioxide emission is reduced by 83%, 82.82%, 82.51% and 73.48 in the same order of the PV modules. Also, the optimal design
is sensitive to the rated power of the WECS and SECS, while the benefit-to-cost ratio and payback period are sensitive to the
storage technology.
