Reactive Power Management in Islanded Microgrid—Proportional Power Sharing in Hierarchical Droop Control [PDF]
IEEE Transactions on Smart Grid, 2015 A microgrid (MG) is a local energy system consisting a number of energy sources (e.g. wind turbine or solar panels among others), energy storage units and loads that operate connected to the main electrical grid or autonomously. MGs provide flexibility, reduce the main electricity grid dependence and contribute to change the large centralized ...

A neural network-based adaptive power-sharing strategy for hybrid frame inverters in a microgrid
Frontiers in Energy Research, 2023 The capacitive-coupling inverter (CCI) is more cost-effective in reactive power conditioning and enhanced reactive power regulation ability when compared with the inductive-coupling inverter (ICI).

A consensus-based distributed voltage control for reactive power sharing in microgrids [PDF]
2014 European Control Conference (ECC), 2014 We propose a consensus-based distributed voltage control (DVC), which solves the problem of reactive power sharing in autonomous meshed inverter-based microgrids with inductive power lines. Opposed to other control strategies available thus far, the DVC does guarantee reactive power sharing in steady-state while only requiring distributed communication

Control Strategy of Reactive Power Sharing in an Islanded Microgrids
Iraqi Journal for Electrical and Electronic Engineering, 2020 Precise power sharing considered is necessary for the effective operation of an Autonomous microgrid with droop controller especially when the total loads change periodically. In this paper, reactive power sharing control strategy that employs central controller is proposed to enhance the accuracy of fundamental reactive power sharing in an islanded ...

A Voltage-Droop-free Reactive Power Sharing Solution in Microgrids
, 2020 The proper active and reactive power sharing is one of the fundamental control targets for distributed generators in microgrids. Currently, the most common solution is to use the active power-frequency (P-f) and reactive power-voltage (Q-V) droop control.

Exponential-function-based droop control for islanded microgrids
Journal of Modern Power Systems and Clean Energy, 2019 An exponential-function-based droop control strategy for the distributed energy resources (DERs) is proposed to reduce the reactive power-sharing deviation, limit the minimum value of frequency/voltage, whilst improving the utilization rate of renewable ...
