Profit maximization is critical in the control of power system networks for both power providers and users. Electrical energy is freely accessible in the electrical grid during off-peak hours, with storage units helping to store excess energy and assist the electrical grid during high-demand situations. Such techniques promote grid stability and ensure safe operation. Because renewable resources are intermittent, energy storage technologies are especially significant in renewable-associated power systems. Vehicle-to-grid (V2G) technology has recently acquired popularity in preserving power grid stability in the presence of renewable resources.V2G technology employs automobiles as mobile storage devices and focuses on the efficient utilization of extra power available during off-peak hours. The goal of this work is to improve the functioning of a V2G system in a power network to reduce energy production costs while increasing system profitability. This study for deregulated power environments also depicts the influence of V2G mixing on system voltage profile and locational marginal pricing (LMP), as well as the performance of the Unified Power Flow Controller (UPFC) on system economics. The MiPower simulation program is used in the study to find the best placement of the power storage unit for the modified IEEE 14-bus system. [ABSTRACT FROM AUTHOR]

ABSTRACT In this paper, the performance of the 3Φ, 6/4 switched reluctance (SR) motor drive has been analyzed using the different power converter topologies. The main objective is to identify the most suitable converter topology for SR motor drive fed electric vehicle (EV) applications. The various power converters such as dissipative, capacitive, magnetic, and bridge converters have been reviewed in terms of operating principle and the calculation of torque ripple. To analyze the drive performance, a comparative analysis is conducted between various power converter configurations including R‐dump, C‐dump, C‐dump with freewheeling transistor (FWT), and asymmetric bridge (ASB) converter. The torque ripple is evaluated for different converters, and it has been claimed that ASB converter has less torque ripple than other topologies. MATLAB/Simulink software tool is used to validate the drive performance for various configurations. A hardware setup includes a FPGA processor of Xilinx Spartan has been embedded to verify the experimental results with the Simulink results. [ABSTRACT FROM AUTHOR]
