Introduction:

We'll explore a comprehensive simulation model focusing on a solar PV battery-powered electric vehicle equipped with a Switched Reluctance Motor (SRM). This simulation model integrates solar power, battery storage, and an SRM motor, providing insights into the dynamic behavior of such a sustainable electric vehicle system.

Simulation Model Components:

  1. Photovoltaic (PV) System:

  • PV panels are connected to a common DC bus through a boost converter.

  • Maximum Power Point Tracking (MPPT) algorithm, specifically Incremental Conductance MPPT, is employed to optimize power extraction from varying solar conditions.

  • Key parameters include initial duty cycle, maximum and minimum duty cycles, and small changes in duty cycle.

  1. Battery System:

  • A 240V battery with a 48 Ah rating is connected to the common DC bus.

  • A bidirectional converter manages power flow between the battery and the DC bus.

  • A proportional-integral (PI) controller ensures the DC bus voltage remains around 400 volts.

  1. Electric Vehicle with SRM Motor:

  • The electric vehicle includes a local load, representing various components, and an SRM motor for propulsion.

  • The SRM motor is a 48V, eight-pole motor.

  • The control logic involves speed command generation, PI speed controller, and a current controller for efficient motor operation.

Results and Dynamics:

  1. PV System:

  • The simulation demonstrates the dynamic response of the PV system to changing irradiation levels.

  • MPPT algorithm adjusts the duty cycle to extract maximum power from the PV panels.

  1. Power Flow and Battery Operation:

  • Power balance in the system is maintained by the bidirectional converter, allowing the battery to charge or discharge based on the power generated by the PV system.

  • DC bus voltage is regulated to 400 volts, ensuring optimal system performance.

  1. Electric Vehicle Operation:

  • The SRM motor follows a predefined speed command, illustrating acceleration, constant speed, and deceleration phases.

  • The motor's electromagnetic torque and speed closely track the reference values, showcasing effective control.

  1. Power Balance:

  • The system ensures a consistent power balance, with the battery transitioning between charging and discharging modes as per PV power availability.


Conclusion:

The simulation model offers a comprehensive view of a solar PV battery-powered electric vehicle with an SRM motor. The integration of renewable energy sources, energy storage, and advanced motor control demonstrates the potential for sustainable and efficient electric vehicle systems.
