Reactive Power Management in Islanded Microgrid—Proportional Power Sharing in Hierarchical Droop Control [PDF]
IEEE Transactions on Smart Grid, 2015 A microgrid (MG) is a local energy system consisting a number of energy sources (e.g. wind turbine or solar panels among others), energy storage units and loads that operate connected to the main electrical grid or autonomously. MGs provide flexibility, reduce the main electricity grid dependence and contribute to change the large centralized ...

Frontiers in Energy Research, 2022 The microgrid (MG) ensures a reliable power supply as it can work in a grid-independent mode. This mode requires a coordinated control strategy among distributed generators (DGs). One major challenge in a grid-independent MG is the reactive power-sharing

Proportional reactive power sharing for islanded microgrids [PDF]
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016 In this paper, droop-based automatic control schemes are presented to control parallel inverter-interfaced distributed generators (DG) in a way that proportional reactive power sharing is possible in islanded microgrids under different structures. This paper modifies the conventional reactive power-voltage (Q-V) droop control strategy used in inductive

Reactive power sharing in microgrid using virtual voltage
International Journal of Electrical and Computer Engineering (IJECE), 2021 The traditional droop control strategy has been applied previously in microgrids (MGs) to share accurately the active power. However, in some cases the result obtained when sharing reactive power is not the best, because of the parameters related to the distances from distributed generators (DGs) to the loads and the power variations.

Distributed secondary controller to ensure proportional sharing of reactive power in AC microgrid
Energy Reports, 2022 In an ac microgrid, reactive power sharing accuracy is affected due to unequal values of interconnecting cable impedances. To resolve this issue, secondary controllers are used to compensate the effect of cable impedances.

Data-Driven Distributed Reactive Power Sharing in Microgrids [PDF]
2019 IEEE 58th Conference on Decision and Control (CDC), 2019 In this paper, reactive power sharing for Photovoltaic (PV) units in islanded microgrids has been formulated as a robust control design problem and is solved using convex optimization method. In addition to reactive power sharing, the disturbance rejection for voltage and active power have been formulated using infinity-norm constraints on the ...

A neural network-based adaptive power-sharing strategy for hybrid frame inverters in a microgrid
Frontiers in Energy Research, 2023 The capacitive-coupling inverter (CCI) is more cost-effective in reactive power conditioning and enhanced reactive power regulation ability when compared with the inductive-coupling inverter (ICI).
