In this article, a novel cooperative secondary voltage/frequency control considering time-varying delays and noises in fading channels is presented for an autonomous alternating current (AC) voltage sourced-based converter (VSC)-based microgrid (MG), including inverter-interfaced distributed generations (DGs). Fading phenomenon makes complex random fluctuations on the voltage and frequency of every DG received from its neighbor DGs. In multi-agent cooperative systems, in addition to the total additive noise and time-variant delay, a multiplicative complex random variable is considered to model the main received signal and its replicas due to multipath propagation. The proposed consensus-based controller is designed by considering fading effects and examines mean square average-consensus considering time-varying delays and uncertainties of the communication system to regulate the voltage and frequency of autonomous AC MGs and provide an accurate real power-sharing. Therefore, by using the proposed protocols, the system sensitivity to fading is decreased, and consequently, the system reliability is increased. Several simulation case studies, such as comparison of the proposed method with previous methods, validate the robustness of our approach against the fading effect.

衰落信道上自治微电网的电压和频率可及性

在本文中，针对基于自主交流（AC）电压源的基于转换器（VSC）的微电网（MG），其中包括逆变器，提出了一种考虑时变延迟和衰落信道中噪声的新型协作二次电压/频率控制。接口的分布式世代（DG）。衰落现象会使从其相邻DG接收到的每个DG的电压和频率产生复杂的随机波动。在多主体协作系统中，除了总的累加噪声和时变延迟之外，还考虑了乘性复数随机变量来建模主要接收信号及其由于多径传播而产生的副本。提出的基于共识的控制器是通过考虑衰落效应而设计的，并考虑时变延迟和通信系统的不确定性来检验均方均值，以调节自主AC MG的电压和频率并提供准确的实际功率共享。因此，通过使用所提出的协议，降低了对衰落的系统敏感性，因此，提高了系统可靠性。若干仿真案例研究，例如将建议的方法与以前的方法进行比较，验证了我们的方法对衰落效应的鲁棒性。系统可靠性提高。若干仿真案例研究，例如将建议的方法与以前的方法进行比较，验证了我们的方法对衰落效应的鲁棒性。系统可靠性提高。若干仿真案例研究，例如将建议的方法与以前的方法进行比较，验证了我们的方法对衰落效应的鲁棒性。
