چکیده
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The interconnection of small modular devices such as photovoltaic, small wind turbines and storage devices ,commonly storage batteries to a Low Voltage distribution system leads to a new energy system known as the Microgrid. This paper presents the modeling and operation of microgrid with wind and photovoltaic resources. The study includes mathematical analysis and simulation of each nonconventional source, as well as their operation to a distribution grid. Part of this study is dedicated towards implementing a control strategy for the storage device, namely the controlling of charging and discharging of the storage device. The study also models various power conversions by use of power electronic devices. The microgrid is observed in with an dc-dc converter when the micro-energy source power, the local ac load , and the distribution grid power change.
