A major portion of a power system's total performance and energy loss is attributable to voltage profiles and power losses in electrical distribution networks (DNs). Enhancing voltage profiles and lowering network losses can result in a more efficient power grid. In the literature, reactive power support has been used with a number of devices to improve DN performance. Some examples are shunt capacitor banks, distribution static compensators (DSTATCOM), and universal power quality condensers (UPQC). A solid-state transformer (SST) that can be built to support the grid has recently attracted a lot of attention. In particular, the SST is being looked at as a possible replacement for the more common fundamental frequency transformer. This paper suggests using the SST's stage-I reactive power support (SI-RPS) function to reduce radial DN losses and improve the voltage profile of the network. With the competing goals of reducing network losses and improving the voltage profile, a planning strategy is given for putting SST installations in the right places and at the right sizes. The simulation results verified the viability and rationale of the suggested model and algorithm for the 69-bus RDN. The outcomes of a number of different situations are detailed in this work. The code for solving the mixed-integer non-linear programming model was developed in MATLAB R2020a. Increasing SST deployment demonstrated an improvement in the voltage profile of the network, along with cutting down on losses significantly.
