Electric vehicle energy efficiency evaluation and supervision system and method thereof for intelligent power grid

Abstract

The invention discloses an electric vehicle energy efficiency evaluation and supervision system and an electric vehicle energy efficiency evaluation and supervision method thereof for an intelligent power grid, which belong to the field of power system automation. The system mainly comprises an energy efficiency database, a smart meter, a background evaluation and supervision control system, an identification device and a bidirectional intelligent control device. The method comprises the following steps of: setting a unique energy efficiency identity (ID) card for each user, recording the energy efficiency parameter information of the user and storing the information in the system; and every time the user is to finish a payment by card by the system, performing identification and calculating the electricity buying price and electricity selling price of the user according to the stored energy efficiency parameter information, and after the user finishes the payment by card, calculating money to be deducted and the money to be returned by using the system, updating the information in the ID card and storing the updated information in the system. By the system and the method, the optimal electricity utilization mode of the intelligent power grid can be realized.

Description

Technical field [0001] The invention belongs to the field of power system automation, and relates to an evaluation and supervision system, in particular to an evaluation and supervision system for energy saving and efficiency enhancement of electric vehicles under a smart grid. Background technique [0002] Today, countries in the world are under the dual pressure of energy crisis and environmental pollution, which prompts countries to change their existing energy development strategies. In recent years, China has also put forward the development idea of ​​building a resource-saving and environment-friendly society. This also puts forward higher requirements for the development of the power system and the quality of power supply services. In this context, the State Grid Corporation of China has proposed the development goal of a unified and strong smart grid based on independent innovation, speeding up the construction of the UHV grid as the backbone, coordinated development of ...
