This study proposes a secondary frequency and voltage control scheme for islanded microgrid based on a fully decentralised control framework with no need of communication links,
In this paper, multi-agent cooperative control strategies have been applied to design a fully-distributed, robust and adaptive secondary voltage and frequency control (SVFC) scheme for
In this sense, the secondary control becomes essential in the system''s resilience, since it is responsible for restoring the frequency and voltage within acceptable values. This study proposes
Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor communication to collectively perform secondary control actions.
First, the article introduces the model used for controller design. Then, utilizing the model predictive control algorithm, it optimizes the objective function by designing constraints that reflect
This paper proposes a nonuniform delay-dependent robust secondary voltage control strategy with a finite-time voltage reference observer for an islanded microgrid.
Compared to some published works, the single-integrator dynamics eliminates the need to compute the derivative of the output voltage. Furthermore, DMPC has been used for all DG units as
Abstract: An adaptive distributed optimal control secondary control scheme under dynamic self-triggered rules is proposed in this paper for AC islanded microgrid to achieve the
Abstract—Secondary control architectures for islanded direct-current microgrids are getting interest since they are necessary to manage the voltage references in order to properly distribute the time
Finally, two structures, i.e., single busbar structure and meshy structure, were utilized to verify the proposed control algorithm, and both effectiveness and universality of the proposed control strategy
