A Grid-Connected PV Inverter with Compensation of Load Active and Reactive Power Imbalance for Distribution Networks

Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...

A Three-Phase Active Power Filter for Harmonic and Reactive; Power Compensation

In this paper, a 3-phase active power filter (APF) is presented to eliminate harmonics and to compensate the reactive power of an uncontrolled rectifier with capacitive loading taken as non-linear load. An APF is realized using 3-phase voltage source inverter (VSI) with dc bus capacitor. Reference source currents are estimated using P-I control over dc bus voltage and 3-phase source voltages. C...

Reactive Power Sharing and Harmonic Voltage Modification in Single Phase Island Micro-Grid with Drop Control

Abstract: When several parallel inverters are in islands operating mode, the droop control scheme is usually used to control the inverters. The droop control method enables the inverters of a Micro-Grid to control the voltage and frequency of the network in a decentralized regulation behavior. The drop control method also enables the inverters to share the required active and reactive powers of...

Active/Reactive Power Control of Three Phase Grid Connected Current Source Boost Inverter Using Particle Swarm Optimization

The future is for sustainable energy (SE) sources [1, 2]. However, to utilize SE sources efficiently one needs to integrate them into the AC Power-Grid. To do so, interface electronic circuits are needed to connect SE sources to local loads or directly to the utility grid. These interfaces are known as the SE-Grid inverters. SE-Grid inverters convert direct current (DC) to alternating current (...
