Distributed Secondary Control for Islanded Microgrids—A Novel Approach [PDF]
IEEE Transactions on Power Electronics, 2014 This paper presents a novel approach to conceive the secondary control in droop-controlled MicroGrids. The conventional approach is based on restoring the frequency and amplitude deviations produced by the local droop controllers by using a MicroGrid Central Controller (MGCC).

Distributed Secondary Control for Islanded Microgrids Considering Communication Delays
IEEE AccessA distributed control of a Microgrid (MG) depends on the communication network for the exchange of information among the Distributed Generators (DGs). Most of the control schemes consider ideal communication among the DGs; however, in practical systems ...

Distributed Secondary Control Method for Islanded Microgrids With Communication Constraints
IEEE Access, 2018 In this paper, a two-layer model for islanded microgrids with communication constraints is proposed, where a key component of the model is a top layer communication network composed of agents over the bottom layer microgrid.

A Comprehensive Review of the State-of-the-Art of Secondary Control Strategies for Microgrids
IEEE Access, 2023 The proliferation of distributed energy resources in distribution systems has given rise to a new concept known as Microgrids (MGs). The effective control of MGs is a crucial aspect that needs to be prioritized before undertaking any implementation ...

An Enhanced Distributed State Feedback for Secondary Control in an Islanded Microgrid [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2022 This paper applies a new state feedback control to a distributed secondary voltage and frequency control in an islanded microgrid. The problem is focused on the output consensus of the multi-agent systems, which is converted to a first-order dynamic ...

Further results on distributed secondary control in microgrids [PDF]
52nd IEEE Conference on Decision and Control, 2013 This work presents several analysis and design results for primary droop control and secondary control in inductive microgrids. Building on our recent work, we study the problem of set point design in droop-controlled microgrids, and provide a choice of droop coefficients leading to the desired power flows.

Data-Driven Secondary Control of Distributed Energy Resources
CoRR, 2021 In this paper, we present a data-driven secondary controller for regulating to some desired values several variables of interest in a power system, namely, electrical frequency, voltage magnitudes at critical buses, and active power flows through critical lines. The power generation system is based on distributed energy resources (DERs) interfaced with
