Adaptive Virtual Impedance Consensus Control for Reactive Power Sharing
2020 IEEE Kansas Power and Energy Conference (KPEC), 2020This paper presents a new control method to ensure effective reactive power sharing in islanded microgrids with multiple distributed generator units (DG units) under mismatched feeder line conditions. A detailed mathematical model of primary and secondary control levels of a hierarchical control are designed to ensure accurate active and reactive power

Control method of islanded microgrid to improve reactive power sharing and power quality
2016 China International Conference on Electricity Distribution (CICED), 2016Due to the influence of feeder impedance, reactive power supplied by distributed generation (DG) based on traditional droop control could not be shared according to their droop gains. This paper proposes a control strategy which is based on virtual impedance, frequency/voltage and reactive power regulation for islanded microgrid.

Proportional reactive power sharing algorithm in Islanded AC microgrid
2015 First Workshop on Smart Grid and Renewable Energy (SGRE), 2015A microgrid (MG) is a local energy system consisting a number of energy sources (e.g. wind turbine or solar panels), energy storage units and loads that operate connected to the main electrical grid or autonomously. MGs require complex management and advanced control.

Accurate Reactive Power Sharing in Renewable-Prioritized Islanded Microgrids
2019 21st European Conference on Power Electronics and Applications (EPE '19 ECCE Europe), 2019An accurate reactive power sharing scheme aiming to prioritize renewable sources is proposed and implemented under modified droop control in islanded microgrids. In order to improve reactive power sharing accuracy, an interfacing inductor and grid voltage estimation strategy is used. Simulation and experimental results show the efficacy of the approach.

A harmonic and reactive power sharing control strategy for islanded microgrids
2015 Chinese Automation Congress (CAC), 2015For an islanded microgrid with local linear loads and public nonlinear loads, this paper proposes a control strategy to achieve better reactive power sharing and harmonic current sharing based on second-order general integrator (SOGI) model and virtual impedance. First, the SOGI alternative structure filters out fundamental current and harmonic current

Decentralized Reactive Power Sharing and Frequency Restoration in Islanded Microgrid
IEEE Transactions on Power Systems, 2017P-f and Q-V droop methods are the most common decentralized control methods in islanded microgrid. Although with the P-f droop method, an accurate active power sharing can be achieved among distributed energy resources (DERs), by Q-V droop, the reactive power sharing among DERs often deteriorates due to its highly dependence on the power line ...
