As the deregulated electricity market is moving towards competition, various ancillary services, including reactive power management, frequency control, and voltage control, are essential for maintaining system security. This paper aims to identify a transparent reactive power cost allocation technique necessary for fair payment distribution among customers and providers based on the reactive power sources and loads identified by the system operator. The existing method, known as the modified Y bus method, is compared with the proposed improved Y bus method of reactive power allocation, which includes line charging admittance, proportional sharing, and equal sharing approaches. The effectiveness of the proposed method is illustrated using simulation results from both a sample 5 bus system and the IEEE 24 bus system, applying MATLAB programming for computation. The analysis of these simulation results highlights the advantages and effectiveness of the improved Y bus method in reactive power cost allocation. This work contributes to the body of knowledge, ensuring that the voltage levels within the system are maintained within specified limits, thereby enhancing overall system reliability and efficiency.
