Data-Driven Control for Interlinked AC/DC Micro grids Via Model-Free Adaptive Control and Dual-Droop Control - 2017

PROJECT TITLE :

Data-Driven Control for Interlinked AC/DC Micro grids Via Model-Free Adaptive Control and Dual-Droop Control - 2017

ABSTRACT:

This paper investigates the coordinated power sharing problems of interlinked ac/dc microgrids. An appropriate management strategy is developed to regulate the interlinking converter (IC) to understand proportional power sharing between ac and dc microgrids. The proposed strategy mainly includes two components: one) the primary outer-loop twin-droop control technique together with secondary control; and 2) the inner-loop knowledge-driven model-free adaptive voltage control. Using the proposed scheme, the IC, simply just like the hierarchical controlled distributed generator units, will have the flexibility to manage and restore the dc terminal voltage and ac frequency. Moreover, the design of the controller is only based mostly on input/output measurement knowledge, but not the model any additional, and also the system stability will be guaranteed by the Lyapunov methodology. The detailed system architecture and proposed control methods are presented in this paper. Simulation and experimental results are given to verify the proposed power sharing strategy.
