From traditional capacitor banks to hybrid power quality

Power Factor Correction (PFC) has evolved from simple capacitor banks to comprehensive Power Quality (PQ) solutions as electrical networks have become increasingly complex. Traditional capacitor...

Grid-forming ability: from battery energy storage to grid asset

The power system is changing faster than ever. Across Europe and globally, conventional synchronous power generation is being replaced by renewable generation, HVDC connections, and...

Practical comparison: Active Front End drives vs. centralized active harmonic filtering

In this blog, I will discuss methods for mitigating harmonic distortion caused by Variable Frequency Drives (VFDs), also known as Variable Speed Drives (VSDs) or...

The most critical steps in BESS site commissioning

In every Battery Energy Storage System (BESS) project, there is a defining moment when everything comes together: commissioning. Commissioning is not just another project milestone....

Are all STATCOMs the same?

STATCOM stands for Static Synchronous Compensator and is part of the Flexible AC Transmission System (FACTS) family. In modern power grids, STATCOMs are widely used...

IEEE 519 maximum demand current: Interpretation, pitfalls, and practical approach

In its standard interpretation, IEEE 519 (2022) allows a situation in which harmonic compliance can be achieved simply by increasing the load, without reducing harmonic...

Round-Trip Efficiency as a performance guarantee for Battery Energy Storage Systems

Round-Trip Efficiency accounts for the energy losses and therefore energy costs during BESS operation phase. But what does RTE mean and how is it measured?...

Power quality: common problems, root causes, and proven mitigation

Modern manufacturing depends on stable, clean electrical power. As plants add Variable Frequency Drives (VFDs), automation, robotics, high-power charging, and electrified thermal processes, electrical networks...
