Distributed generators supply varying combinations of real and reactive power, which directly influence total power losses and voltage stability across radial distribution networks. A structured evaluation assessed how increasing penetration levels of different generator types alter network voltage profiles and power losses. Two novel power voltage stability indices were created to identify the most sensitive network buses suitable for generator integration. Generator capacity was incrementally expanded on these chosen buses by one per cent of total network load demand. When tested on standard IEEE 33-bus and 69-bus benchmark systems, the analysis demonstrated that penetration levels could reach between 45 and 76 per cent on the 33-bus network and 48 to 55 per cent on the 69-bus network without triggering increases in power loss. In addition, higher penetration levels consistently improved the overall voltage profile index relative to baseline operating conditions.
Connecting renewable and distributed generators to local electricity networks can cause voltage issues or energy losses if unmanaged. Demonstrating that distribution networks can accommodate significant levels of distributed generation without increasing losses provides valuable guidance for grid planning. Identifying the most suitable connection points ensures networks maintain steady voltages while absorbing higher volumes of decentralised power.
This methodology offers utility operators and grid planners an analytical framework for siting distributed generation assets and determining maximum safe hosting capacities. The technique could be integrated into grid simulation and management software tools used by distribution companies. Because the findings are validated solely on standard simulated benchmark networks, the work represents early-stage analytical research that requires testing on operational distribution grids before practical commercial deployment.

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