6 FAQs about [Island Microgrid Secondary Voltage Control]

Can distributed controllers perform secondary frequency and voltage control in Islanded microgrids?

Abstract: In this paper, we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor communication to collectively perform secondary control actions.

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.

Is there an intelligent secondary controller for Islanded microgrids?

In this context, the present article proposes an intelligent secondary controller for islanded microgrids using the Deep Deterministic Policy Gradient (DDPG). The DDPG controller changes the output power of the storage elements to secure the voltage and frequency stability.

Is there a secondary control scheme for Islanded microgrid operation?

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.

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.
