Effects of clock deviations on the performance of microgrids based on virtual synchronous generators
IET Power Electronics, 2021 An inverter‐based microgrid is a small‐scale power network governed by a distributed control system. In this system, the nodes are the digital controllers of the power inverters, normally located at separate points within the microgrid.

Optimal Control of Nonlinear Multivariable Systems [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2009 This paper concerns a study on the optimal control for nonlinear systems. An appropriate alternative in order to alleviate the nonlinearity of a system is the exact linearization approach.

Collective Large-scale Wind Farm Multivariate Power Output Control Based on Hierarchical Communication Multi-Agent Proximal Policy Optimization [PDF]
arXiv, 2023 Wind power is becoming an increasingly important source of renewable energy worldwide. However, wind farm power control faces significant challenges due to the high system complexity inherent in these farms. A novel communication-based multi-agent deep reinforcement learning large-scale wind farm multivariate control is proposed to handle this ...

Topological equivalence canonical forms for linear multivariable systems without control [PDF]
arXiv, 2022 In this paper, we discuss the classification problem for linear time-invariant multivariable systems without control. It turns out that the observability and stability are invariant for topological equivalent systems. Abstract results concerning system decomposition according to eigenvalues and observability are obtained. Finally, as concrete examples,

Augmentation of Generalized Multivariable Grid-Forming Control for Power Converters with Cascaded Controllers [PDF]
, 2022 The classic design of grid-forming control strategies for power converters rely on the stringent assumption of the timescale separation between DC and AC states and their corresponding control loops, e.g., AC and DC loops, power and cascaded voltage and current loops, etc.
