Renewable Energy Sources (RES) into the RDN has environmental benefits such as 
environmental friendliness (no emissions), free availability, abundance in nature, and 
so on [2-4]. 
The most commonly used DG systems in the residential sector are solar photovoltaic 
(PV) technology, small wind turbines (WT), fuel cells, natural gas-fueled ultrasounds, 
and emergency standby generators, usually fueled by diesel or gasoline. However, the 
commercial and industrial sectors use solar photovoltaic panels, hydropower, biomass 
combustion, biomass or natural gas fuel cell combustion, reciprocating internal 
combustion engines, and standby generators powered by petroleum-type diesel 
systems. Integration of DG units does not guarantee the reliability and stability of the 
system if they are placed in non-optimal places with different sizes. Instead of 
improving reliability and maintaining system stability, this will affect the voltage 
profile and increase system losses [5-8]. The optimal placement of the DG has taken 
on great importance due to its various advantages. However, integrating DG into an 
existing system will be an important and challenging task. As DG integration changes 
the behavior of the network from passive to active. Bidirectional power flow ultimately 
increases system losses and affects the reliability and stability of operation [6]. 
Planning to integrate a DG into an existing system requires optimal location, size, type 
of DG, and network connectivity. This reduces overall power loss, improves the system 
voltage profile and stability, reliability, safety, power quality, power factor, and overall 
system efficiency. Incorrect placement of WG units will distract from all of the above 
advantages [9]. Therefore, it is very important to place the DG unit in an optimal 
location and with a suitable size.
