“…Distributed generator (DG) is a possible substitute for installing a new centralized generation station, particularly in the era of deregulation and it has several benefits such as low investment risk and short installation period (Gissey et al, 2021;Khaligh and Buygi, 2020;Martinez-Bolanos et al, 2020;Moret et al, 2020;Yang et al, 2020), modules with small capacity that can monitor variations in load very closely (Jiang et al, 2020;Mahmud et al, 2020;Somefun et al, 2020), small physical size suitable for installation at proximity to users' end, and availability of a large range of DG technologies (Nagaballi and Kale, 2020;Yang et al, 2021). However, it is important to note that when DGs are to be introduced into a distribution network, consideration should be to optimally site and size DG units otherwise, there will be an increase in power losses and a decrease in reliability levels (Balu and Mukherjee, 2020;Deb et al, 2020;Farzinfar et al, 2020;Galgali et al, 2021;Kizito et al, 2020;Manna and Goswami, 2020;Shuaibu et al, 2020;Truong et al, 2020). In recent time, there have been rise in the study of distributed generation in power system analysis.…”
