Abstract
In this paper a new methodology is proposed to investigate the impacts of network structure on the optimum design of microgrids. The proposed microgrid consists of PV, wind, battery storage and diesel generator. By introducing some approximations the relationships between wind turbine and PV module were expressed as linear functions of wind speed and solar radiation respectively. Therefore, the problem is formulated as a linear optimization problem that minimized the annual cost of the system. A computer program is developed in Matlab to formulate the optimization problem. Output of the optimization procedure show the viability of the proposed method by reducing the carbon emission by 70.40 % compared to operating the system on diesel generator alone. The result also shows that DC and AC coupled microgrid could reduce the system annual cost of hybrid microgrid by 5 and 2.8 % respectively. In addition, the effects of diesel prices, battery storage parameter, storage technology on the optimum system configurations have been investigated.
