Sliding-Mode and Lyapunov Function Based Control for a DC Microgrid with Renewable Generation a Solid Oxide Fuel Cell and Battery Storage

In this paper, we propose a sliding mode and Lyapunov Function based control for a DC microgrid. The microgrid involving renewable distributed generators (PV system and wind turbine), energy storage system (Battery), a solid oxide fuel cell a dump load (aqua_electrolyzer) connected to the same dc bus and an inverter connected to LCL filter which is connected to an AC load Fig. 1. The behavior of the whole system is represented by mathematical models derived from the different sources of the microgrid the dump load and the storage system are presented in Sect. 2. The decentralized control of the microgrid components are depicted with synoptic figures presented in Sect. 2. The energy management algorithm is adopted to ensure the power balance under variable power generation. Simulation results demonstrate that the proposed control method has acceptable performance, including robust tracking and a velvety transition under generation scenario and load power variation in the large range.
