本文探討由太陽能、風渦輪機與燃料電池混合發電系統建立而成之微電網及其運轉性能，此系統包含太陽能發電系統、風力發電系統、燃料電池發電系統、靜態虛功補償器以及智慧型控制器。風機和太陽能為提供給系統的主要能源，而燃料電池電解槽作為提供給系統的備份能源且為一長期的儲存裝置。本文利用MATLAB/Simulink來建立微電網控制的混合發電系統並模擬分析，及應用靜態虛功補償器提供系統無效功率，來調整混合發電系統的電壓。為了使混合發電系統皆可操作在最大功率點以及系統實功率快速達到穩定的響應，本文提出的智慧型控制器，包含廣義迴歸類神經網路(General Regression Neural Network, GRNN)與徑向基底類神經網路-滑模控制(Radial Basis Function Network-Sliding Mode Control, RBFNSMC)，將其應用於風力發電系統與太陽能發電系統之最大功率追蹤。其中風力發電系統之葉片旋角控制器是利用徑向基底類神經網路-滑模控制器，由控制器輸出的旋角，來控制風力渦輪機的輸出功率及發電機輸出功率，以達到最大功率追蹤。而太陽能發電系統則利用廣義迴歸類神經網路控制器，由控制器輸出信號來控制直流/直流控昇壓器，以達到最大功率輸出。

This thesis discusses the modeling of a micro-grid with photovoltaic (PV)-wind-fuel cell (FC) hybrid energy system and its operations. The system consists of the PV power, wind power, FC power, static var compensator (SVC) and an intelligent power controller. Wind and PV are primary power sources of the system, and an FC-electrolyzer combination is used as a backup and a long-term storage system. A simulation model for the micro-grid control of hybrid energy system has been developed using MATLAB/Simulink. A SVC was used to supply reactive power and regulate the voltage of the hybrid system. To achieve a fast and stable response for the real power control, the intelligent controller consists of a Radial Basis Function Network-Sliding Mode Control (RBFNSM) and a General Regression Neural Network (GRNN) for maximum power point tracking (MPPT). The pitch angle of wind turbine is controlled by RBFNSM, and the PV system uses GRNN, where the output signal is used to control the DC/DC boost converters to achieve the MPPT.
