The network-induced delays have a great impact on microgrid performance and stability. In this paper, we proposed distributed cooperative secondary control with stochastic Markov time-varying delays, by which both output voltage/frequency restoration active power sharing can be obtained. A new small-signal model of the system is developed, model-based information Kalman observer introduced to acquire estimated state vector. Then, global closed-loop accommodated derived, corresponding...
This article proposes an optimal distributed secondary voltage control method based on coordinated reinforcement learning (DCRL) algorithm in the time-delayed microgrid. First, a protocol through sparse communication network is designed using consensus-based and Lyapunov–Krasovskii theory. Then, by combining consensus with together, novel DCRL utilized to dynamically adjust controller gains. Since online intelligent algorithm, it can adaptively improve performance presence of various...
The hierarchical networked control has attracted many attentions in the field of islanded microgrid (MG). However, how to reduce effects caused by random packet loss communication is still need be studied. In this study, authors proposed a fully distributed cooperative secondary optimal for both frequency and voltage restoration. A consensus Kalman filter based estimator (DCKF‐estimator) introduced obtain estimation output state with loss. Then, incorporating DCKF‐estimator into...
Abstract The network sampling rate is important in the overhead transmission line monitoring system. A larger can provide more available monitored data to be transmitted, which effectively improve response speed emergency events of Considering harsh environment wireless network, quality‐of‐service (QoS) requirement becomes an issue for multi‐hop transmission. Thus, this paper, end‐to‐end delay optimisation algorithm string‐topology proposed, by maximum packet arrival and allowable obtained...
Pre-whitened space-time adaptive processing (STAP) can obtain fast convergence rate and achieve better clutter suppression performance in heterogeneous environment. However, pre-whitened STAP shows significantly degradation the presence of array errors. To solve this problem, we propose a novel method based on echo to calibrate errors online. Firstly, are represented as orientation-dependent gain-phase errors; Then, main-lobe every direction will be used calibration source, corresponding...
