Optimal Reactive Power Dispatch (ORPD) is conducted to identify the voltage levels of all generators, optimize transformer tap ratios, and determine the ideal MVAR injection values for shunt compensators. In this paper, we present the EBO-CMAR algorithm for the first time, addressing both deterministic and stochastic ORPD challenges. Additionally, we propose a modified test system featuring a scenario-based approach that accounts for uncertainties in load demands and renewable energy sources, while also identifying optimal locations for shunt capacitors to enhance voltage stability. Despite progress, there remain research gaps regarding how to establish the optimal system configuration for reactive power control, particularly in adapting to changes in demand and renewable energy generation. The results of this study provide valuable insights into the strategies that power system operators can adopt in this context. Simulation results demonstrate that our proposed algorithm outperforms the most recent methods documented in current literature for the standard IEEE 30 and 57 bus test systems. A transparent comparison with existing studies adhering to the same constraint values reveals that voltage deviation has been reduced to 0.0845 p.u. in the IEEE 30 bus test system and 0.6063 p.u. in the IEEE 57 bus test system, achieving the best results recorded thus far. Furthermore, by determining the optimal locations for shunt capacitors, we have shown that the new power system configuration can improve the voltage stability index by 2.62% and reduce the number of shunt compensator devices by 9.55%.
