Distribution System Enhancement via Renewable-DG based D-STATCOM Allocation in the Presence of EV Charging-Stations

Rapid technological advancements in various sectors drive the increasing adoption of DG. With this rise in DG utilization to meet the demand for real power, there is also a growing need for reactive power. Therefore, this study introduces a planning approach for Renewable-DG based DSTATCOM to meet the growing requirements for both real and reactive power. Also, the impacts of EVCS integration have been considered. The efficacy of this approach is assessed on an IEEE 85-bus Distribution System (DS) using Sine-Cosine Algorithm (SCA) based on an innovative Multi-Objective Function (iMOF). The iMOF considers Real Loss (Real
Loss
), Reactive Loss (Reactive
Loss
), and Voltage-Deviation Profile (VD
Profile
). Three Scenario Analysis (SA) are presented to analyze the results, with SA3 demonstrating superior technical benefits, computation, and convergence performance. This research provides insights into the potential of the planning methodology and its positive impact on integrating Renewable-DG based D-STATCOM with EVCS into DS.
