6 FAQs about [Microgrid Secondary Voltage Control]
Is there a robust secondary voltage control strategy for a microgrid?
This paper proposes a nonuniform delay-dependent robust secondary voltage control strategy with a finite-time voltage reference observer for an islanded microgrid. A discrete-time consensus algorithm is introduced to track the output voltage. By model transformation, a closed-loop microgrid control system is obtained.
What is the control objective of a secondary controller for DC microgrids?
The control objective(9)of the secondary controller for DC microgrids, satisfyingAssumption 3, can be ensured with the proposed voltage controller(16), if and only if the matrix Γ in(27)is Schur stable, which implies all the eigenvalues of matrix Γ are within the unit circle.
Can a cooperative secondary voltage control scheme be compensated autonomously in microgrids?
This study proposes a cooperative secondary voltage control scheme in islanded microgrids, which can be seen as multi-agent systems with distributed generators being agents. Therefore, the voltage deviation caused by the primary control level can be compensated autonomously in a microgrid using a directed communication graph.
How to implement secondary voltage control of Islanded microgrid as a leader-follower consensus problem?
To implement secondary voltage control of the islanded microgrid as a leader–follower consensus problem, a virtual leader needs to be defined to provide the voltage reference. Also, only a portion of the agents can receive information from this virtual leader. As the result of the distributed control, all the agents can synchronise to the leader.
How can voltage deviation be compensated autonomously in a microgrid?
Therefore, the voltage deviation caused by the primary control level can be compensated autonomously in a microgrid using a directed communication graph. An auxiliary centralised event-triggered controller is designed to deal with feedback control law.
How a microgrid test system is used in a distributed secondary control strategy?
