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.

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 ...

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 ...

2013 IEEE Energy Conversion Congress and Exposition, 2013
To address inaccurate power sharing problems in autonomous islanding microgrids, an enhanced droop control method through adaptive 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.

Reactive power allocation in pool based power system utilizing proportional sharing method
2010 IEEE International Conference on Power and Energy, 2010This paper proposes an approach of reactive power allocation with considering the transmission losses, which is based on manipulation of proportional sharing principle. After power flow solution is computed, the equivalent transmission line model is introduced by integrating shunt admittances into nearby buses.

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.

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 ...

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 ...
