What is a Power Conversion System PCS?

With the enormous amount of energy being consumed in today's world and government policies to minimize carbon emissions, the shift to renewable energy makes reliably delivering energy where and when it is needed more challenging than ever. As a result, demand for energy storage systems is also on the rise. A critical component of any successful energy storage system is the power conversion system (PCS). 

A Power Conversion System (PCS) is a device for bidirectional conversion of electrical energy connected between the battery system and the grid and/or load. This device should have charge and discharge functions, active and reactive power control functions and off-line switching functions.

The PCS is the intermediary device between the storage element, typically large banks of (DC) batteries, and the (AC) power grid.


How does a PCS work?

To achieve the bidirectional conversion of electric energy, a power conversion system is a component connected between the energy storage battery system and the power grid. The PCS charges the batteries in the event of excessive power generation. The PCS provides the power with the stored energy if the grid need extra energy.

Power Conversion System and Battery Energy Storage System

AC/DC bidirectional converters, control elements, switching components, and cooling compose a power conversion system. There are many layers of remote control for the system. This is designed to regulate the battery’s charge or discharge, as well as the grid’s active and reactive power. In order to obtain information about the state of the battery pack and cells, the PCS can simultaneously connect with the battery management system (BMS) using a number of interfaces and protocols (RS-485, CAN, Fibre-Optics, Ethernet). As a result, the battery can be charged and discharged safely, and the energy storage system can run without interruption.

The Power Conversion System (PCS) is a device that converts electric energy from one form to another for storage or release of the energy in or from the battery. In order to get the energy stored in the Energy Storage System (ESS), which is emerging as a solution to the energy shortage, PCS converts the energy to the form the end user needs.


What is the role of PCS?

The type of electricity stored in the battery through the ESS is direct current (DC) and what is supplied to electronic devices in general is alternating current (AC). As they are used for different purposes, AC needs to be converted to DC to store electricity in the ESS and vice versa for releasing the stored electricity. The PCS enables bidirectional power conversion between AC and DC, serving as both a charger and transmitter.

What is the role of PCS?

Apart from power conversion, PCS controls the quality of electricity including active and reactive power while monitoring the voltage and operating status. Also, in case of a power outage, it can protect the power systems and goes into operation independently using batteries even without a power supply.
