Distributed Reactive Power Sharing Control for Microgrids With Event-Triggered Communication
IEEE Transactions on Control Systems Technology, 2017Due to the inherently distributed and heterogeneous nature of the microgrids, distributed control can be a promising approach to improve the stability, reliability, and scalability of the microgrids compared with centralized control strategies. This paper studies the distributed reactive power sharing problem for a microgrid with connected ac inverters.

An Enhanced Islanding Microgrid Reactive Power, Imbalance Power, and Harmonic Power Sharing Scheme
IEEE Transactions on Power Electronics, 2015 To address inaccurate power sharing problems in autonomous islanding microgrids, an enhanced droop control method through online virtual impedance adjustment is proposed. First, a term associated with DG reactive power, imbalance power, or harmonic power is added to the conventional real power-frequency droop control.

Enhanced Active and Reactive Power Sharing in Islanded Microgrids
IEEE Systems Journal, 2020The intermittency of renewable energy makes the control of islanded microgrids more difficult than that of the grid-connected mode. In conventional methods, the controller is designed to regulate the system frequency and voltage only based on the droop control theory.

An Improved Reactive Power Sharing Method for an Islanded Microgrid
IEEE Transactions on Industry Applications, 2019Conventional droop control is traditionally used for achieving proportional power sharing in an islanded microgrid. Active power-sharing becomes proportional to the ratings of the inverters by applying the conventional droop control. However, reactive power-sharing is not proportional because of unequal line impedances and asymmetric load distribution ...

Advanced localized reactive power sharing in microgrids
Electric Power Systems Research, 2017Abstract The droop characteristics have gained much attention for controlling the distributed generation (DG) units in an islanded microgrid, since they obviate the requirements for communication infrastructure and have relatively fast response time.

An improved controller for reactive power sharing in islanded microgrid
Electrical Engineering, 2021The control to stabilize the frequency and voltage is the main goal of controlling the islanded microgrid. The microgrid can include different inverters, which are connected in parallel to each other by lines that have different impedances. The loads in the microgrid include local and public loads. With the different line impedances and local loads, it

Sharing of Active Power Supply and Reactive Power Compensation for Parallel Inverters
2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition, 2009A control technique is developed for parallel operating inverters with no control interconnections in microgrid. This technique uses only locally measurable feedback signals to allow some independent inverters to share the active power for loads, while the others to provide reactive power compensation for loads, both in proportional to their capacities.

Cost Sharing Mechanism for Reactive Power Management Amidst P2P Energy Sharing
2020 IEEE Power & Energy Society General Meeting (PESGM), 2020With the increasing penetration of distributed energy resources (DERs) at the demand side, power quality in the distribution network has become a critical problem. Currently, the operator/utility would pay for the cost increment caused by out-of-order DERs.

Active and Reactive Power Sharing in Parallel Operated Inverters
MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference, 2006Active and reactive power sharing of parallel operating inverters has been investigated in this paper. The power sharing is achieved by adjusting the frequency and voltage amplitude of each unit. Each unit has its own controller and these controllers make sure that the total active and reactive power is shared by each unit in proportion with their ...

Reactive Power Sharing Analysis in Islanded AC Microgrids
2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019Primary regulation of islanded Microgrids is one of the most relevant topics in an academic and industrial world. IEEE Std 1547-2018 defines the functionalities of GridSupporting inverters and one of the control goals is the correct reactive power sharing.
