Feasibility study of operating an autonomous power system in presence of wind turbines, A practical experience in Manjil, Iran

Commonly facing some irregular situations such as natural disasters and experiencing power interruptions as a consequence, the power grid in Manjil located in the north of Iran needs to be capable of power delivery to its local load points in an isolated manner. This paper aims to study the feasibility of this situation once local wind turbines are used as the power generation facilities. The imbalances of power supply and demand due to the high variation of wind power is overcome in this paper via employing and comparing two hydro-wind and diesel-wind power systems which are comprised of energy storage systems. This paper also investigates the balance feasibility of power supply and demand once the system is isolated from the whole power grid and offers an approach to identify the size and type of energy storages in this respect. The proposed method is proved to be an economic approach and results in an acceptable level of system reliability.
