报告题目：Meshed DC Microgrids and its Power Flow Controller
报告摘要：
Microgrids are currently being built throughout the world to meet local energy demands with low carbon emissions. The use of direct current (DC) in microgrids brings various advantages: It removes the problem of reactive power and skin effects. It increases power efficiency by reducing the number of power converters. Meshed microgrids are another research issue to enhance the reliability, modularity and efficiency of the system while reducing the amount of copper used. The Power flow controller (PFC) is a key element for meshed DC microgrids. Indeed, this device is able to balance the electric power between the lines of a node in the mesh, which is required to maintain stability and prevent the overloading of some lines. The primary control objective is to achieve power control on the line connected to each terminal of the PFC despite the uncertainty of the grid. The considered PFC is equipped with a reservoir capacitor. Voltage regulation of this capacitor is also addressed, as a secondary control objective. We propose modular state-space modeling for the chosen converter topology. As the system is nonlinear, a differential flatness-based nonlinear control is used to achieve the control objectives.

Prof. Xuefang Lin-Shi received the M.Sc. degree from Claude Bernard Lyon 1 University, France, in 1988. In 1992, she received Ph.D degree in applied computer science and control from INSA Lyon (Institut National des Sciences Appliquées de Lyon), France. Since 1993, she has been with the Electrical Engineering department of INSA Lyon, where she is currently a professor. She is now with Ampère Laboratory in Lyon, France. Her research interests concern control application for electrical drives and power electronics systems, with special emphasis on the stability analysis of DC/DC converters and design of controllers, optimization of high-performance digital control of high-frequency and low-power integrated switching power supplies, predictive control of power electronic hybrid systems, sensorless motor controls. In recent years, her research interests include DC microgrid converter control. She is the author of more than 180 papers (journal, book chapters, refereed conference proceeding papers…).
