Abstract: The integration of renewable power sources with power grids presents many challenges, such as synchronization with the grid, power quality problems and so on. The shunt active power filter (SAPF) can be a solution to address the issue while suppressing the grid-end current harmonics and distortions. Nonetheless, available SAPFs work somewhat unpredictably in practice. This is attribut...

The usage of electric vehicles (EV) increased in recent years as the design and performances are nearly similar to petrol vehicles. main source energy for EV is taken from grid charging. So, penetration EVs alternating current (AC) creates more power quality issues like voltage sag, swell harmonics current. This can also be produced renewable resources photovoltaic (PV) generation. PV used dire...

Abstract This paper proposes a cascaded low-pass filter (CLPF) scheme for the control of unified power quality conditioner (UPQC) installed enhancing an electric vehicle (EV) charging station. With incorporation UPQC, EV station draws sinusoidal currents at unity factor and supply voltage is maintained nominal value charger input. In CLPF scheme, α–β components load current are individually pro...

A Unified Power Quality Conditioner (UPQC) is designed using a Neutral Point Clamped (NPC) multilevel inverter to improve the power quality. When designed for high/medium voltage and power applications, the voltage stress across the switches and harmonic content in the output voltage are increased. A 3-phase 4-wire NPC inverter system is developed as Power Quality Conditioner using an effectual...

Mitigating power quality issues in distribution systems is of utmost importance to both electricity consumers and suppliers as it improves the system’s efficiency, reduces costs, maintains continuous supply, diminishes requirement for frequent maintenance. Custom devices were introduced eliminate like voltage sags, swells, transients, imbalances, current harmonics arising systems. Unified condi...

This paper investigates the power quality problems which occur frequently in supply and suggests a method to mitigate by implementation of UPQC. P-Q generally concern with voltage sags/swells harmonic currents. Custom Power (CP) devices that these have gained more attention recent decades. UPQC is Designed, modelled setup experimentally sag/swells currents three phase systems. consists Dynamic ...

An intelligent control strategy is proposed in this paper which suggests the Optimum Power Quality Enhancement (OPQE) of grid-connected hybrid power systems with solar photovoltaic, wind turbines, and battery storage. Unified Conditioner Active Reactive (UPQC-PQ) designed Atom Search Optimization (ASO) based Fractional-order Proportional Integral Derivative (FOPID) controller Hybrid Renewable E...

This paper discusses a distributed generation system consisting of grid-connected solar PV and battery-integrated Unified Power Quality Conditioner (UPQC). Embedded in the array, UPQC consists series shunt converter connected back through common DC link. In this system, power quality problems clean energy, such as harmonics, voltage drops, ripples, are compensated by injecting active energy int...
