Power Quality Enhancement in Islanded Microgrids Via Closed

The high proportion of nonlinear and unbalanced loads results in power quality issues in islanded microgrids. This paper presents a novel control strategy for harmonic and unbalanced power allocation among distributed generators (DGs) in microgrids. Different from the existing sharing strategies that allocate the harmonic and unbalanced power according to the rated capacities

Abstract: The high proportion of nonlinear and unbalanced loads results in power quality issues in islanded microgrids. This paper presents a novel control strategy for harmonic and unbalanced

Improving the Power Quality of Island Microgrid With Voltage

Processes, 2019. The islanded mode of the microgrid (MG) operation faces more power quality challenges as compared to grid-tied mode. Unlike the grid-tied MG operation, where the voltage magnitude and frequency of the power system are regulated by the utility grid, islanded mode does not share any connection with the utility grid.

A Novel Approach for Power Quality Improvement in

distribution and transmission scenario. The objective of power quality improvement has enforced the introduction of susceptible and complex devices in the vicinity of electrical infrastructure. Nonstandard voltage, disturbing power, and frequency are a few of the power quality-related problems. This power quality problem results in

Control of Interlinking Converter for Power Quality Improvement

This article deals with control of a hybrid ac/dc microgrid (MG) comprising photovoltaic array (PV), battery energy storage (ES), small hydroelectric (SH) generator, and wind energy conversion system (WECS). WECS is connected via static power electronic switch (SPES). The notion of ac/dc MG has emerged due to progress in both ac- and dc-based

Power quality enhancement in microgrid

Microgrid becomes one of the key spot in research on distributed energy system. Since the definition of the microgrid is paradigm by the first time, investigation in this area is growing continuously and there are numerous research projects in this moment over the world. The main objective of this paper is to make a comprehensive survey focused on the power quality

Reinventing power quality enhancement: deep reinforcement

A pioneering technique for optimizing the functionality of a Photovoltaic-Unified Power Quality Conditioner (PV-UPQC) is proposed in this work by replacing conventional synchronous reference frame (SRF)-based control with deep reinforcement learning (DRL). The PV-UPQC is integrated with a microgrid to improve power quality and system efficiency. In this
