Research on Grid-Connected Charge-Discharge Control Strategy of Electric Vehicles Based on Clean Energy

Abstract

Introduction: With the increasingly serious global energy shortage and environmental pollution problems, new energy vehicles have been widely concerned as a clean and efficient way of transportation. Among new energy vehicles, electric vehicles have become the mainstream direction of future transportation development with their advantages of zero emission, low noise and high efficiency. However, the popularity and large-scale application of electric vehicles need to solve the problem of energy management in the charging and discharge process.

Objectives: This paper studies the grid-connected charging and discharge control strategy of electric vehicles based on clean energy, aiming to realize the maximum utilization of clean energy and the stable operation of the power system.

Methods: This paper first introduces the basic principles and key technologies of grid-connected charging and discharging of electric vehicles, and then analyzes the application status and challenges of clean energy in electric vehicle charging. Then, this paper proposes a grid-connected charging and discharge control strategy based on clean energy. This strategy predicts the charging and discharge demand of electric vehicles and the output of clean energy, and makes a reasonable charging plan and discharge control strategy, so as to realize the maximum utilization of clean energy and the stable operation of the power system. Finally, the effectiveness and feasibility of the proposed control strategy are verified by simulation experiments.

Results: The experimental results show that this strategy can significantly reduce the impact of electric vehicles on the power grid and improve the benefits of clean energyWhile ensuring the stable operation of the power system.

Conclusions: In this study, the in-depth discussion and simulation experiment of the grid-connected charging and discharge control strategy of electric vehicles based on clean energy, and verified its effectiveness in balancing the grid load and optimizing the utilization of clean energy..
