Power Conversion System

Power Conversion System (PCS) is a bidirectional current controllable conversion device that connects the energy storage battery system and the grid.Its main function is to accurately and quickly adjust the voltage, frequency and power between the grid and the energy storage system, to achieve constant power and constant current charging and discharging and smooth fluctuation power output.The energy storage converter not only meets the inverter requirements of the traditional grid-connected converter to convert DC to AC, but also meets the bi-directional conversion requirements brought by the "charge + discharge" of the energy storage system. It has the function of charging and discharging the battery, and is suitable for a variety of occasions such as photovoltaic, wind power generation power smoothing, peak filling, and micro grid.

Product Application Scenarios

PCS can be applied to new energy power stations, microgrids, smart grids, transportation, ships, wind power, solar energy and other industries.

Specific applications include energy time-shift, peak-valley arbitrage, dynamic capacity expansion, micro-grid systems, frequency and peak modulation of power systems, etc.

In the user side of the energy storage system, the PCS storage converter can undertake peak valley arbitrage, through the period of electricity price is low, in the period of high prices for discharge, achieve low charge high discharge carry, save the park overall power cost.
