  7. Abstract:
  8. In order to reduce damage caused by power outages on rare events that lead to long-term disconnection of microgrid from utility grid, isolated mode performance of microgrids including wind and hudro turbines with energy storage systems is considered in this study. Using wind energy as a renewable resource is considered as an appropriate choice for power production in microgrids. However, the uncertainty in wind turbines power generation is something challenging. The existence of water resources near the wind farms causes a special opportunity for operation of these resources along with wind turbines. This thesis aimed at balancing energy supply and demand in island mode of microgrid, has designed the size of power generation and storage devices. Method used in this thesis is based on simulation of alternatives for microgrid elements’ sizes in the time interval in which microgrid is isolated from power system and intelligent search of alternatives which meets both aims: high reliability and low economic cost. Simulation is carried out based on the time series of power generation/consumption of elements, and intelligent search of feasible space is based controlled elitist genetic algorithm. The proposed methodology in this project is also applied on a hypothetical mocrogrid case in Manjil and Rudbar and results in sizing and sensitivity analysis to some important parameters are presented.
