I. Introduction
Flexible installation and operation are features of distributed generation (DG), which can supply power flexibly close to the load side, minimize system power loss, and enhance the dependability and efficiency of power system operation [1]–[3]. However, the geographic context has an impact on natural resources like wind and light, making the production of solar systems and wind power unpredictable. Due to the numerous distributed power sources that had access to the distribution network, the conventional methods for planning distribution networks are no longer applicable. If irrational planning is done, some grid security issues, including deterioration of system voltage quality, an increase in network loss, trend reversal, and so forth, may arise [4]–[5].
