Frequency Regulation of Electric Vehicles Integrated Multi-area Power System Under Deregulated Scenario Using Novel Dual Mode Controller

Abstract

The research work focuses on the automatic generation control (AGC) of a multi-source two area power system with vehicle-to-grid technology under deregulated environment. The electric vehicles are the future for the clean automobile sector and hence the charging and discharging process for the vehicles have an important role in the power system stability. The main role of AGC is to minimize the system frequency variations and hence attempt has been made to design novel DUAL mode control scheme. The dual mode control basically takes the magnitude of the error and effectively chooses between proportional and integral control for better action. This paper has proposed a Dual mode PID controller whose performance is put to comparison with PID and 2 DOF PID controller. The controller gains are tuned by a newly proposed Dragonfly algorithm. The system is to be simulated under base case and bilateral contract market scenario of deregulated environment. Analysis is also made for both the charging and discharging modes of electric vehicles. The robustness of the proposed controller is to be established by analyzing the dynamic system performances in terms of settling time, maximum overshoot, and undershoot.
