Electric Energy Dynamic Metering System Based on Grid Load

Abstract

The invention relates to a grid-load-based dynamic electric energy metering system comprising a processing device and metering terminals. The processing device is used for calculating a redundancy situation of a power grid networking power and calculating a metering adjusting coefficient for external sending based on the redundancy situation, wherein a metering adjusting system is used for carrying out metering according to actual electricity consumption to obtain adjusting electric consumption. The metering terminals include a first metering module for carrying out metering to obtain actual electricity consumption and a second metering module for carrying out metering to obtain adjusting electric consumption; and the second metering module is connected with the first metering module and the processing device respectively. Compared with the prior art, the provided metering system has the following beneficial effects: with the intelligent power grid, electric charge valuation is carried out by using the adjusting electric consumption obtained based on the power grid networking power redundancy situation, so that the operation becomes flexibly; and a user terminal can be guided to carry out power peak adjustment. Compared with the exiting peak-valley electric charge peak regulation guiding way, the provided way enables the peak regulation to become accurate.

Description

technical field [0001] The invention relates to an electric energy metering system, in particular to an electric energy dynamic metering system based on grid load. Background technique [0002] The adjustment of economic structure will become the focus of the government's work for a long period of time. Along with this structural adjustment, my country's extensive economic growth mode will definitely be changed. Over the past 30 years of reform and opening up, the coefficient of elasticity of electricity consumption in my country has gradually declined, and the early strategy of focusing on the development of heavy industry has gradually shifted to the development of modern service industries. In recent years, the elasticity of electricity consumption has gradually dropped below 1. It is foreseeable that the long-term trend is In the future, the elasticity coefficient of electricity consumption will further decrease. [0003] In the environment of economic cycles and global ...

Problems solved by technology

[0004] Compared with changing the economic structure, it may be more realistic to solve the energy loss caused by the imbalance of peak and valley periods of power load. At present, the form of peak and valley electricity prices is generally used to guide residents to use electricity at staggered peaks. However, with the development of social economy, The method of peak-valley electricity price has encountered more and more limitations. First, the peak-valley time period is unbalanced among regions; secondly, the peak-valley time period is not balanced in seasonal distribution; The peaks and valleys are probably not one peak and one valley, and the second is that there will be multiple peaks and valleys alternately in a day
