This paper discusses the modeling and analysis of Networked Control Systems (NCSs) where sensors, actuators, and controllers are distributed and interconnected by a common communication medium. Therefore, multiple distributed communication delays as well as multiple inputs and multiple outputs are considered in the modeling algorithm. In addition, the asynchronous sampling mechanisms of distrib...

This paper presents an online two-stage Q-learning based multi-agent (MA) controller for load frequency control (LFC) in an interconnected multi-area multi-source power system integrated with distributed energy resources (DERs). The proposed control strategy consists of two stages. The first stage is employed a PID controller which its parameters are designed using sine cosine optimization (SCO...

We consider the problem of optimal distributed controller design of semidecentralized controllers for a special class of spatially distributed systems. This class includes spatially invariant and distributed systems with an inherent temporal delay in the interaction of distant sites. We consider the problem of optimal design of distributed controllers where controller information passing is as ...

Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...

In this paper, a distributed generation including diesel generators, wind turbines, and microturbines are introduced, and their mathematical model is described using the Taylor expansion method. With the goal of computational complexity eliminating, the reduced order model (ROM) of microgrid components is considered. The results of the ‌‌studies indicate that the microgrid frequency is unstable...

When designing distributed controllers for large-scale systems, the actuation, sensing and communication architectures of the controller can no longer be taken as given. In particular, distributed optimal controllers implemented using more complicated architectures typically outperform distributed controllers implemented using simpler ones – however, it is also desirable from an economic standp...

This paper is concerned with the optimal distributed control problem for linear discrete-time deterministic and stochastic systems. The objective is to design a stabilizing static distributed controller whose performance is close to that of the optimal centralized controller. To this end, a necessary and sufficient condition is derived to guarantee the existence of a distributed controller that...
