Step changes in the inverter’s reference power show the strategy’s quick adaptation to reactive power demands, while maintaining a stable active power supply. Furthermore, active power control disconnects the BESS when it approaches its lower SoC limit in a near-depleted battery scenario.
Notably, it excels in adapting to rapid load changes, maintaining active power at the specified reference while dynamically adjusting reactive power for voltage stability, which is ideal for MGs with dynamic load profiles. The inverters’ reference output voltages (Vref) are determined using a power flow analysis on the system.
Hence, the Bidirectional Wireless Power Transfer (BDWPT) technology is essential and emerging to address challenges in the EV domain. This paper surveys the necessity for bidirectional WPT, various coil designs suitable for bidirectional operation, converter topologies, and communication techniques and standards.
This study introduces a control strategy designed to optimize the operation of BESSs. This control strategy optimizes the BESS operation by dynamically adjusting the inverter’s power reference, thereby, extending the battery cycle life.
However, conventional plug-in charging methods necessitate human intervention for EV participation in V2 G operations. Consequently, wireless power transfer (WPT) technology emerges as a viable solution, eliminating the need for manual intervention in enabling bidirectional operation for EVs.
In the simulation, both inverters are configured with a reference active power of 30 kW, starting with an initial SoC of 100% for the first BESS and 60% for the second BESS. The reference output voltage per unit (p.u.) for both BESS units, determined based on power flow results for the benchmark, is 0.991 and 0.981233, respectively.
