I. Introduction
Distributed generation (DG) based on renewable energy sources is gaining popularity worldwide as a way to tackle energy and environmental issues. However, high penetration of DG into the distribution network (DN) can lead to problems such as voltage rise, reverse power flow, increased losses, and decreased power quality [1]. The variability of renewable energy sources makes it challenging to predict the power output of DG systems [2]. To overcome these challenges, it is crucial for planners to adopt a methodical approach to determine the most suitable capacity for DG installations within a DN. This approach must consider uncertainties associated with DG power output, such as those from wind turbines (WTs) and photovoltaic (PV) systems, as well as load consumption. Additionally, it is essential to avoid any technical limitations that may arise in the process.
