Impact of Distributed Generators Penetration Level on the Power Loss and Voltage Profile of Radial Distribution Networks

The Distributed Generator types have different combinations of real and reactive power characteristics, which can affect the total loss voltage support/control radial distribution networks (RDNs) in ways. This paper investigates impact DG’s penetration level (PL) on profile RDNs based DG types. are modeled depending they inject. profiles obtained under various circumstances were fairly compared using index (VPI), assigns a single value to describe how well voltages match ideal voltage. Two novel effective stability indices developed select most sensitive candidate buses for penetration. To assess influence PL profile, sizes gradually raised these by 1% load demand RDN. method was applied IEEE 33-bus 69-bus RDNs. A 45–76% is achieved 48–55% without an increase loss. VPI improved with increasing base case scenario.
