Power System

Battery storage is the traditional method of connecting renewable energy (RG) to the electric grid (BESS). In this cascaded combination of a grid-connected inverter, a battery, and RG, the power …

When inverters drive an AC motor, the harmonic components of the output voltage caused additional iron and copper losses in the magnetic cores of the motor. Since inductance is supposed …

With the increasing use of renewable energy sources, the need for reliable and efficient grid-side inverter fault detection and protection is becoming more important. Because the magnitude of fault current …

This study provides a hybrid approach to PV/wind/battery system control. A transformer-coupled bidirectional DC-DC converter is used to control the power flow. The proposed system is designed to meet the …

Wind power, another attractive and well-developed renewable energy source, has recently emerged. A power electronic interface is required to connect a wind energy conversion system (WECS) to the load or …

Since an induction motor (IM) is commonly used as a drive in industry, it must be protected against common faults such as overvoltage, overcurrent, overload, overtemperature, and undervoltage. Timers, contactors, …

This article is about the voltage stability of receivers. Voltage stability and level are concepts that are inseparable. Although this is a good indicator that you are close to the …

There is an urgent need for a mechanism for precisely identifying the battery’s state of charge (SOC), as LiFePO4 (LFB) batteries are being used in more portable devices. In this …

The research presented here reports enhanced-boost quasi-Z-source inverters (qZSI) using two switching impedance networks (continuous input current configuration and discontinuous input current configuration). These suggested inverter designs, which are comparable …

These findings show how an integrated UPQC-P array performs dynamically for critical loads, such as solar photovoltaic arrays (SPV-UPQC-P). The SPV-UPQC-shunt P’s compensator, connected across the load, transfers electricity from …
