Plug-and-play energy storage peak shaving device convenient to deploy and peak shaving method thereof

Abstract

The invention provides a plug-and-play energy storage peak shaving device convenient to deploy, and the device comprises an insertion piece which is connected with a phase detector, is also connectedwith an inverter, and is used for household power input and energy storage module output; the phase detector which is used for detecting the phase and frequency of household electricity and is electrically connected with a control module; the control module which is used for controlling the on-off of a charging circuit and a discharging switch; the charging circuit used for charging an energy storage module; the energy storage module used for storing energy and discharging; the discharging switch used for controlling the energy storage module to discharge; and the inverter which is used for converting the direct current of the energy storage module into alternating current. According to the invention, the plug and play is realized, energy storage equipment is used for discharging and compensating the active power at the peak of power utilization, the energy storage equipment is charged when the active power is sufficient, switching-off power limitation or off-peak power utilization isnot needed, and the daily power utilization requirements of enterprise production and common users can be met.

Description

technical field [0001] The invention relates to the technical field of power peak regulation, in particular to an easily deployable plug-in energy storage peak regulation device and a peak regulation method thereof. Background technique [0002] The main purpose of power storage peak shaving is to solve the problems of tight power supply during peak power consumption, insufficient active and reactive power reserve, low utilization rate of transmission and distribution capacity, and low transmission efficiency. At present, the main means of power storage and peak regulation is to build pumped storage power stations on the power source side; and to pull power cuts and staggered peak power consumption on the power consumption side. This method of power cuts is a very primitive and crude peak-shaving method, which seriously affects the production of enterprises and the electricity demand of ordinary users. Contents of the invention [0003] The invention solves the problems o...
