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 (Power Conversion System) consist of converters, control system, transformer & switch gear (where needed). Thanks to its modular design we can quickly configure Power Conversion Systems for both large commercial & industrial plants as well as utility scale units with one of the highest power densities available on the market.


What is a Battery Energy Storage System BESS?

Battery Energy Storage Systems ESS, are rechargeable batteries that can store energy from different sources and discharge it when needed. BESS consist of one or more batteries and can be used to balance the electric grid, provide backup power and improve grid stability.

Amid an increased focus on renewable energy sources, BESS (Battery Energy Storage System) compensates for the intermittency of these sources, providing essential value for operators by enabling a stable supply of electricity thus avoiding curtailment of renewable energy and maximizing their revenue.


Energy Storage System and Power Conversion 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.

From renewable energy producers, conventional thermal power plant operators and grid operators to industrial electricity consumers, and offshore drilling platforms or vessels, BESS offer highly efficient and cost-effective energy storage solutions.

With BESS, you can even generate new revenue streams as it allows energy arbitrage or directly reduce your electricity bill via peak shaving.


Where is the BESS used?

      • Renewables – Battery energy storage aligns solar and wind generation peaks with demand peaks.
      • Residential and Commercial - lower energy costs, improves load factor, and manages demand peaks.
      • Utility distribution grid - balances fluctuating demand at peak hours while reducing grid overload.
      • Industrial loads - provides backup power for critical loads, improves load factor, and manages demand peaks.
      • Electrification of transportation - reduces demand on the grid and enables fast DC charging without increasing demand charges.

active harmonic filter

50A Smart Active Harmonic Filter Module

Active harmonic filter(AHF) is connected in parallel with non-linear loads, and uses one set of CT to detect the load current. It calculates each order harmonic current by FFT algorithms in its DSP microchips, and then generates a compensating current with the same amplitude but opposite phase angles to the detected harmonic current, which cancels out the original load harmonics.Not only eliminates harmonic current from the load side, but it also mitigates harmonic voltage caused by harmonic currents. The AHF system can also improve power factor (PF) and correct load imbalances in the power system.
