Abstract

Due to ever increasing energy consumption, rising public awareness of environmental protection, and steady progress in power deregulation, alternative (i.e., renewable and fuel cell based) distributed generation (DG) systems have attracted increased interest. Wind and photovoltaic (PV) power generation are two of the most promising renewable energy technologies. Fuel cell (FC) systems also show great potential in DG applications of the future due to their fast technology development and many merits they have, such as high efficiency, zero or low emission (of pollutant gases) and flexible modular structure. The modeling and control of a hybrid wind/PV/FC based DG system is addressed in this dissertation. Different energy sources in the system are connected to a common dc link bus. Dynamic models for the main system components, namely, wind energy conversion system (WECS), PV energy conversion system (PVECS), fuel cell, power electronic interfacing circuits, battery are developed. The type of fuel cell that have been modeled in this dissertation: proton exchange membrane fuel cell (PEMFC). Power control/load mitigation control of a stand-alone FC system, the maximum power point tracking (MPPT) control for PVECS and wind system SOC of battery addressed in the dissertation. Based on the dynamic component models, a simulation model for the proposed hybrid energy system has been developed using MATLAB/Simulink. The overall power management strategy for coordinating the power flows among the different energy sources is presented in the dissertation. Simulation studies have been carried out to verify the system performance under different scenarios using conventional and fuzzy logic control. The results show that the overall power management strategy is effective and the power flows among the different energy sources and the load demand is balanced successfully.
