Abstract

The invention relates to a household electric energy management system and method based on a peak-valley time period of a power system. The technical characteristics are as follows: the household electric energy management system comprises a power grid, an interconnection interface, a household power utilization management system, a household power utilization control system, a power generation system, an energy storage system and a power utilization load. According to the system and the method, the interconnection interface of a power distribution network is connected via a distributed power supply to perform interaction between a power user and a power system, such that the requirement for management of a power demand side can be responded in real time, and the reasonable power supply of a user load at each peak-valley time period as well as the reverse power supply to the power grid is implemented.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to a household power management system and method based on power system peak and valley periods. Background technique [0002] With the development of smart grid, the application of power demand side management is gradually promoted to small and medium power users. [0003] The following three patents were found through searching: (1) A new type of intelligent control algorithm for home energy management system (application number CN201310586819.6), mainly for DR control of high-power home appliance loads for residential users, and for household distributed power The energy supply mode is selected according to the specific energy supply mode, fully considering the comfort range setting of the home appliance by the user, and the concept of the comfort limit index is proposed according to the current working state of the home appliance, and the dynamic priority of all ...
