Battery energy storage systems (BESSes) act as reserve energy that can complement the existing grid to serve several different purposes. Potential grid applications are listed in Figure 1 and categorized as either power or energy-intensive, i.e., requiring a large energy reserve or high power capability. They can also be classified according to the deployment time scale, which ranges from millisec...
Technological Progress and the Challenge of Harmonic Distortion in Modern Electrical Systems Technological progress is unstoppable. Every new innovation aims to make life easier and more efficient. From advanced production processes to cutting-edge consumer electronics, the modern world relies heavily on technology. However, the very electronics that make these advancements possible often introduc...
Introduction Power quality refers to the characteristics of electric power supplied to end users, particularly its ability to ensure the proper functioning of electrical devices. With the increasing use of sensitive equipment such as programmable logic controllers, variable frequency drives (VFDs), and computers in modern industries, the tolerance for power disturbances such as voltage dips, swell...
Abstract: Utility power system harmonic problems can often be solved using a comprehensive approach including site surveys, harmonic measurements, and computer simulations. This case study presents the results for a commercial facility harmonic evaluation. The simulations were completed using the PSCAD program. The analysis evaluates the effects of transformer connections to determine the har...
Harmonics & VFDs: Causes, Solutions, and Key Insights How VFDs Cause Harmonic Issues Variable Frequency Drives (VFDs) are commonly used to control motor speed and optimize energy consumption in industrial systems. However, VFDs work as nonlinear loads. This means they draw currents that are not smooth, even if the supply voltage is a perfect sine wave. This happens because VFDs change AC power...
What are Reactive Power and Reactive Power compensation？ Reactive power is a key part of AC electrical systems—it’s the energy that flows back and forth between the power source and the load. Unlike active power, which does the actual work like powering lights or running machines, reactive power doesn’t directly get used up. But it plays a crucial role in keeping voltage levels s...
Before diving into the architecture and types of battery energy storage systems (BESS), it is essential to familiarize ourselves with key terminology commonly used in this field. Various parameters are crucial in describing the behavior and performance of BESS. · Capacity [Ah]: This represents the amount of electric charge the system can supply to a connected load while maintaining an accep...
Advantages of YT Electric SVC Over Capacitor Banks In industrial and commercial power systems, maintaining a balanced power factor is critical for efficient operation, reduced energy costs, and overall system stability. Reactive power compensation is a key technique used to improve power factor and stabilize the voltage profile of the system. Traditionally, capacitor banks have been w...
