Accurate Reactive Power Sharing for Microgrid Using Distributed Adaptive Virtual Impedance

2020 IEEE 29th International Symposium on Industrial Electronics (ISIE), 2020
Distributed generators (DGs) are usually dispersed along with the microgrids, which may spread out in a wide area, the impedances of transmission lines between every two DGs may be different. Therefore, uneven distribution of reactive power among parallel DG inverters with fixed virtual impedance would be induced eventually, which not only results in ...

An enhanced power sharing strategy for islanded microgrids using adaptive virtual impedances

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
In this paper, an enhanced power sharing strategy employing adaptive virtual impedances for Q-ω and P-V droop-based islanded microgrids (MGs) is proposed. The proposed scheme improves the performance of dynamic response and system stability while accurate power sharing is obtained. The low-bandwidth communication is utilized to send the power commands.

Improving Reactive Power Sharing in Microgrids by Adaptive Virtual Impedance Approach

2020 IEEE/IAS 56th Industrial and Commercial Power Systems Technical Conference (I&CPS), 2020
As a new emerging approach, Virtual Synchronous Generator (VSG) control for interfacing inverters in renewable energy-based microgrids has attracted significant research interest. However, VSG control cannot ensure proportional reactive power sharing among distributed generation (DG) units when unequal transmission line impedances are involved ...

A New Adaptive Virtual Impedance based Fault Current Limiter for Converters

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
Fault current limiter (FCL) can be used to prevent converters from being damaged and miscoordination of the protective relays. FCL must be designed to have high efficiency, fast response, and low implementation cost. Accordingly, this paper proposes an adaptive virtual impedance (VI) based FCL for a four-wire system.

Virtual Synchronous Generator Stability Enhancement and Power Oscillation Suppression with Adaptive Virtual Impedance Control

IEEE Journal of Emerging and Selected Topics in Power Electronics
With the rapid growth of renewable power generation (RPG), grid inertia gradually decreases. Therefore, the virtual synchronous generator (VSG) is proposed to enhance the inertia and damping of the power system. High-penetration RPG, characterized by intermittency, stochasticity, and output volatility, could cause grid impedance variations, thereby ...
