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 in microgrids: An information-theoretical approach
2017 IEEE 3rd Colombian Conference on Automatic Control (CCAC), 2017In this work, we use a multi-agent learning framework based on information theory concepts such as maximum entropy and rate distortion theory in order to control the reactive power sharing in an islanded microgrid. The distortion between each agent (distributed generator) and the environment behavior determines a fitness function that is used as a ...

Distributed-based reactive power sharing in islanded microgrid
2017 Chinese Automation Congress (CAC), 2017This paper proposed an adaptive impedance control method in multi-bus distributed islanded micrigrid to share reactive power accurately and suppress circulating current. The multi-bus distributed microgrid is more complicated than one-bus because of its different bus voltages and variable structure.

An Enhanced Islanding Microgrid Reactive Power, Imbalance Power, and Harmonic Power Sharing Scheme
IEEE Transactions on Power Electronics, 2015To 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.

Microgrid reactive and harmonic power sharing using enhanced virtual impedance
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013To address the load sharing problem in islanding microgrids, this paper proposes an improved approach which regulates the distributed generation (DG) unit interfacing virtual impedance at fundamental and selected harmonic frequencies. In contrast to the conventional virtual impedance control where only a line current feed-forward term is added to the ...
