Modeling & control of hybrid AC/DC micro-grid micro components
摘要
Abstract
With the increasing of DC loads, the traditional AC micro-grids can not meet the demands of system load diversity and economy. Hybrid AC/DC micro-grid gradually becomes a research hotspot. In the simulation study, the random, time-varying and nonlinear characteristics of the Distributed Generation (DG) make the DG modeling, algorithm realization and the coordination and cooperation between DG and energy storage relatively complex in hybrid micro-grid. Based on engineering application requirements, a hybrid AC/DC micro-grid system containing the DC distribution grid is built. Furthermore, the physical models and control strategies of the corresponding micro components are proposed. Finally, this paper mainly focuses on the simulation of micro components under different working conditions. The simulation results show that the proposed hybrid AC/DC micro-grid structure is reasonable, and the control strategies and performance of the components are good. The whole system has fast response speed, and can well satisfy the requirements of system security and stability.关键词
