Voltage quality is a one of the major concerns in distribution systems. Distributed Generations (DGs) have potential to improve voltage quality, if optimally planned and operated. Considering problem DG siting sizing, this paper aims at integrating technical factors, particularly planning DGs. Hence, methodology proposed which optimizes presence DGs can be used as objectives multi-objective or ...

This paper presents a new method named “Life cycle model” for optimal placement of Distributed Generators in a distribution network. The impact of DG at the distribution level is investigated with an emphasis on active power losses and allocation for minimizing the cost of losses and capacity investment costs simultaneously. An application of the proposed method for a distribution network is pr...

Distributed generation (DG) is becoming a prominent key spot for research in recent years because it can be utilized emergency/reserve plans power systems and quality improvement issues, besides its drastic impact on the environment as greenhouse gas (GHG) reducer. For maximizing benefits from such technology, crucial to identify best size location DG that achieves required goal of installing i...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...
