Electric water heater peak shifting parameter adjusting control system and load management method thereof

Abstract

The invention discloses an electric water heater peak shifting parameter adjusting control system and a load management method thereof. The electric water heater peak shifting parameter adjusting control system is provided with a communication module, a single-chip microcomputer, a display setting module, a temperature detection module, a fault alarming module, a watchdog circuit, an output control module, a first heating element and a second heating element. Power consumer information and historical load data are extracted; distribution weights of yearly, monthly and weekly electrical loads of power consumers at 24 periods are calculated; distribution of daily 24-period sharp-peak flat-valley electrical loads of the power consumers is predicted according to the distribution weights of the yearly, monthly and weekly electrical loads of the power consumers at 24 periods; prediction periods of the daily 24-period sharp-peak flat-valley electrical loads of the power consumers serve as electrical parameters of the virtual energy storage control technology to conduct peak shifting control over the electrical loads. The peak shifting load control over peak clipping and valley filling of a power grid is achieved; the peak segment power consumption of electric water heaters is reduced, and the valley segment power consumption is increased; the peak-valley load difference of power grid operation is reduced, and the purposes of saving energy and reducing consumption are achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power grids, and in particular relates to an electric water heater peak shifting parameter adjustment control system and a load management method thereof.
