Modeling and Simulink of HEVs with V2G and HESS integration
Implementation plan:
—————————
Step 1: Initially, we constructed a Toyota Prius Gen-III based HEV–V2G System with ICE, motor, battery, supercapacitor, bidirectional DC–DC converter, aerodynamic, resistance blocks, and a bidirectional V2G charger.
Step 2: Then, we design and run the SUMO and export the vehicle’s speed profile.
Step 3: Next, we create a subsystem to input this profile for the hybrid EV model.
Step 4: Next, we integrate a Fuzzy Logic Controller (FLC) for smoother power transitions including AQI-based drive-mode switching and HESS power assistance.
Step 5: Then, we simulate the model and collect data such as voltage, current, SOC, SOH and power flows across ICE–Motor–Battery–SC.
Step 6: Next, we implement Cruise control logics to validate power cut-offs.
Step 7: Next, we implement a Rule-Based EMS for basic power split, safety limits, and V2G decision logic using thresholds based on collected data.
Step 8: Next, we develop a Model Predictive Control (MPC) logic for optimal energy flow between ICE–Battery–SC and grid participation by predicting future power demands using the collected data.
Step 9: Next, we analyze battery SOC/SOH limits, thermal safety constraints, HESS support behavior, and V2G charging–discharging impacts to understand EMS decisions about battery health and operational safety.
Step 10: Finally, we plot performance metrics for the following:
10.1: Time (h) vs. Current (A)
10.2: Time (h) vs. Voltage (V)
10.3: Time (h) vs. SOC (%)
10.4: Time (h) vs. SOH (%)
10.5: Time (h) vs. Power (kW)

Note:
——-
1) If the proposed plan does not fully align with your requirements, please provide all necessary details—including steps, parameters, models, and expected outcomes—in advance. Kindly ensure that any missing configurations or specifications are clearly outlined in the plan before confirming.
2) If there’s no built-in solution for what the project needs, we can always turn to reference models, customize our own, different math models or write the code ourselves to fulfil the process.
3) If the plan satisfies your requirement, Please confirm with us.
4) Project based on Simulation only.
