DC microgrids are constructed from inverter-based distributed generations (DG) to achieve a various range of applications. Such configuration eliminated DC/AC conversion and simplified the control objectives design, being DC-grid voltage regulation and curretn sharing. This paper develops a stochastic distributed washout filter-based control scheme that can achieve current sharing of DGs and voltage restoration of DC bus in mean square subject to additive noises and time delays over fading networks. Since the cyber channels are exposed to inherent additive noises and time delays, the information exchange among multiple and cooperative DGs may be disturbed in fading communication networks, where fading may either be due to noises, delays, and shadowing from obstacles affecting the wave propagation. As a results, fading makes every DG receives incomplete/imprecise information from its neighbors. To dispel the adverse influences of noises and time delays over fading networks, a washout filter-based distributed noise-resiliency control algorithm is developed for DC microgrids, in which only the current state variable is exchanged among DGs with the local decentralized voltage controller. By introducing stochastic theory and Lyapunov stability function, the criteria for the stability analysis and delays boundedness considering noise interferences is derived to ensure the stability operation of the whole closed-loop DC network. The obtained results show the effectiveness of the proposed strategy by a tested DC microgrid in OPAL-RT real-time simulator.
