The analysis of hybrid system as DG in smart grids by the use of loss sensitivity coefficient method

Along with the recent improvements in the smart grids technology, the analysis of different types of Distributed Generations (DGs) in the system has become more important. Therefore in this paper, a hybrid system including photovoltaic, wind turbine, Solid Oxide Fuel Cell (SOFC) with storage device as a power source is utilized in the smart-grid distribution systems. As the result of intrinsic variations in these types of power sources, the use of hybrid system can improve the operation reliability of the network. In this situation, the requirements to preserve the environment, loss reduction and voltage profile enhancement is supplied sufficiently. Also, the loss sensitivity coefficient is utilized in this paper to find the optimal location and size of the hybrid system in the 33 bus IEEE distribution system.
