Multi-rate electric energy meter and working method thereof

Abstract

The invention provides a multi-rate electric energy meter and a working method thereof. The multi-rate electric energy meter comprises a communication module, a collection module, a metering chip anda charging module, wherein the communication module is used for communicating with a power grid data center, acquiring unit electricity price, and assigning a time stamp to the unit electricity priceto form electricity price data; the collection module is used for collecting current and voltage; the metering chip is used for collecting and processing input current and voltage to obtain electric energy, and assigning a time stamp to the electric energy to form electric energy data; and the charging module is used for acquiring the electric energy data and the electricity price data, processingto get the relationship between the electric energy and the unit electricity price, and forming electricity price data. The multi-rate electric energy meter has the advantages that through an electric charge calculation scheme of tracking the running load of a power grid in real time with the electric energy meter and adjusting the unit electricity price, the unit electricity price is combined with the actual running load of the power grid, and the off-peak power consumption of users is realized by a price regulation measure, so that the problem of peak-load shifting of the power grid is solved radically; the power generation can be effectively and scientifically planned; the power transmission and power distribution investment is saved; and the energy utilization rate is improved.

[0003] However, the current smart meters use time as the basis for determining the peak, peak, and valley boundaries of grid power consumption. Through the pricing of different unit electricity charges for peak power, peak power, and low-valley power, price regulation is used to achieve peak-shaving and valley-filling. However, this does not play the role of peak-shaving and valley-filling and balancing grid load in essence and origin, because its electricity bill pricing is only related to time, and it is not based on tracking the real-time load of the grid to formulate unit electricity prices, so it cannot achieve real peak-shaving and valley-filling effect

Moreover, the investment in electric power is invested according to the maximum load of the power receiver. The power receiver cannot understand the current grid load and consumes a lot of electricity at peak times, which will make the grid run under high load for a long time and increase the cost of grid equipment.
