Accurate Reactive Power Sharing
, 2021 For microgrid in islanded operation, due to the effects of mismatched line impedance, the reactive power could not be shared accurately with the conventional droop method. To improve the reactive power sharing accuracy, this chapter introduces an improved droop control method.

ITER Reactive Power Compensation Systems: analysis on reactive power sharing strategies
2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019 The goal of nuclear fusion is one of the most important challenges in contemporary research and technological development. Its achievability will completely change the energy scenario and reduce the dependence on fossil fuels in the production of electricity. ITER project is focusing the efforts of many countries and researchers in the demonstration of

A Practical Structure and Control for Reactive Power Sharing in Microgrid
IEEE Transactions on Smart Grid, 2019Due to the uncertainty of feeder impedance, conventional droop control-based power sharing scheme presents poor reactive power sharing accuracy in microgrid. As microgrid configuration becomes more and more complicated, reactive power sharing between various distributed generation (DG) equipment is very challenging. To achieve proper power sharing with

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.

A Reactive Power Sharing Strategy of VSG Based on Virtual Capacitor Algorithm
IEEE Transactions on Industrial Electronics, 2017In the islanded microgrid, distributed generators are controlled with virtual synchronous generator (VSG) strategy to simulate rotor inertia and droop characteristics of synchronous generators, in order to enhance the voltage and frequency support capabilities. Since the capacity and location distribution of each VSG is random, the VSG output impedance,

A review of reactive power sharing control techniques for islanded microgrids
Renewable and Sustainable Energy Reviews, 2021Abstract The paper presents a review of the approaches developed to solve the problem of primary voltage control and reactive power sharing (Q/V primary control) among converter interfaced production units present in a microgrid. First of all, a general survey of the methods is proposed with specific focus on communication-less methods that are ...

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
