With the increasing consumption of electricity and the aggravation of global warming, encouraging EV owners participates in V2 G energy storage by using financial compensation measures during peak periods, which is significant for conserving energy and reducing emissions of the power grid and alleviating the power supply shortage. Aiming at the peak load of the power grid, this paper puts forward a three-stage regulation strategy based on step-wise economic incentive method. At the same time, a mathematical model with the lowest grid power financial loss, the minimum carbon emission and the minimum loss of power supply probability is constructed. By selecting a domestic area as the research object, three kinds of control schemes are proposed to optimize the actual system aiming at its peak load level. The schemes not only reduce carbon emission and achieve double win-win of the grid and EV owners, but also improve the reliability of power supply, which verify the effectiveness and practicality of low-carbon control strategy.

With the development of society, the power system plays an important role in the global energy structure. However, facing increasing energy demand and environmental pressure, improving power system efficiency, reducing costs, and ensuring reliability and safety have become key issues. The Internet of Things (IoT) power electronics technology, as one of the research hotspots, integrates IoT and power electronics technology to achieve intelligent and optimized control of power systems through sensors, communication, and control technologies. In order to meet current and future needs, it is necessary to optimize the operation and management of power systems using IoT power electronics technology. By analyzing the application of Internet of Things power electronics technology and the optimal dispatch of power systems, support vector machine algorithms are used to analyze and process equipment data, and perform data monitoring and anomaly detection to promote energy waste reduction and energy saving, and then start from operation and maintenance respectively. Comparative simulation experiments were conducted in five aspects: efficiency, effectiveness of power load prediction and optimization control, effectiveness of intelligent monitoring, operating costs, and data security. The experimental results show that the operation and maintenance efficiency of the power system using IoT power electronics technology has been improved to only 18 h for equipment fault handling. The accuracy of load forecasting optimization control based on IoT power electronics technology reaches 94%. The fault detection accuracy of intelligent monitoring of power equipment based on the power electronics technology of the Internet of Things has reached 96%. At the same time, the Internet of Things power electronics technology was used to improve the power operation mode, so as to promote the monthly electricity sales revenue of 2.77 million RMB. In addition, the effectiveness of IoT power electron
