Description
Summary:Reactive power has gained acknowledgment as an ancillary service, indispensable for generators to ensure the dependable process of power systems. Moreover, it carries the potential to significantly enhance the effectiveness of delivering active power to consumers. Additionally, a strategic injection of reactive power at specific points holds the capability to alleviate transmission constraints, enabling cost-effective power distribution to heavily loaded regions. Given the inherent characteristics of reactive power provision, it necessitates efficient and dependable local procurement and management strategies. However, prevailing models fail to encompass the diverse dimensions of reactive power costs, leading to inefficiencies. Thus, an optimal resolution is imperative to rectify these complexities. This study introduces an innovative market mechanism for delivering reactive power ancillary services (RPAS), with a specific emphasis on its localized implementation. The proposed approach leverages the Sailfish Optimizer and is implemented on the General Algebraic Modeling System platform. The effectiveness of this novel mechanism is demonstrated through application to the IEEE 30-bus and PJM 5-bus systems, incorporating wind energy sources. The objective function takes into account the critical role of reactive power in maintaining bus voltage within acceptable limits and evaluates the availability of reactive power reserves within the system. The adoption of this utility function results in a noteworthy reduction in the total payment associated with RPAS, concurrently leading to an improvement in system-wide bus voltage and the preservation of necessary reactive power reserves across the network.
