Household power saving system suitable for tiered electricity price and time-of-use electricity price

Abstract

A household power-saving system suitable for step electricity price and time-of-use electricity price, characterized in that: it includes a control device, input and output equipment, a control switch group and a household electric meter; the control device includes a micro-controller and a monitoring module; the micro-controller can read Take the power consumption above it; the monitoring module includes the main control module, the first-class household appliance drive module, the second-class household appliance drive module, and the third-class household appliance drive module; the main control module is used for centralized control of the entire system, and its First of all, it is used to initialize the system, accept the household appliance switch information input by the user, and store it in the first, second or third type of household appliance switch information sequence buffer according to its attributes; and separately according to the household appliance switch information sequence buffer Call the first, second and third types of home appliance drive modules for processing. It can solve the problem of reducing the instantaneous power of peak power consumption when reducing the total load of the grid cycle.

Description

technical field [0001] The invention relates to the field of power demand terminals, in particular to a household power-saving system suitable for step electricity prices and time-of-use electricity prices. Background technique [0002] For a long time, my country has adopted a low-price policy for residents' electricity prices, resulting in users who consume more electricity and enjoy more subsidies. In order to promote resource conservation and the construction of an environment-friendly society, and guide residents to use electricity rationally and economically, the National Development and Reform Commission proposes to implement tiered electricity prices for residents' daily electricity consumption. The tiered electricity price encourages everyone to reduce the total electricity consumption in a cycle (for example, within a month or a year), but judging from the peaks and valleys of electricity consumption, it will lead to high peaks (peaks) and lower troughs, resulting ...

AI Technical Summary

Problems solved by technology

However, the current status of the distribution network: the electric energy meter installed in the residential area only measures the user's electricity consumption information, and cannot collect the user's predicted electricity consumption information, nor can it guide the user's electricity consumption according to the functions of the stage electricity price and the time-of-use electricity price. It is difficult to know how to use all kinds of electrical appliances in a month so as to use less high-end electricity prices and not use too many larger appliances during high-priced electricity consumption hours

That is to say, it is currently difficult to solve the problem of reducing the instantaneous power of peak power consumption and saving electricity consumption by users while reducing the total load of the power grid cycle
