A New Optimal Distribution Generations Placement Method in an Islanded Distribution Networks Considering Voltage and Power Control Modes

Due to integration and penetration of Distributed Generations (DGs) in power distribution systems, an efficient method to locate different types of DGs in microgrids and isolated distribution networks took place with considering objectives such as power losses and improve the voltage profile. DGs are connected to low voltage networks by power electronic converters, as these converters operate in power control mode (PCM) or voltage control modes (VCM). DGs placement by considering PCM and VCM of converters has a positive effect on power networks. This paper presents a new method to find optimal placement by adding DG units to islanded distribution network with considering PCM and VCM by using Power loss, voltage sensitivity analysis and active power margin with considering voltage limitation as objective functions. The performance of the method by DigSilent software is applied on IEEE 13-bus and IEEE 33-bus distribution networks in islanded mode.
