功率硬體迴路(Power Hardware In the Loop, PHIL)模擬是一種即時模擬，允許實際的功率設備交互於模擬的電源系統。隨著基於可再生能源的發電裝置(REBG)連接到主電網的需求不斷的增加，使功率硬體迴路模擬獲得高度的關注，因為其可以達到貼近實際的因素。因此，可以透過功率硬體迴路模擬準確預測可再生能源的發電裝置(REBG)對電網的影響。
本文的功率硬體迴路設置為與直流微電網對接的光伏系統，且使用的配置不同於常規的功率硬體迴路配置:
1. 在功率硬體迴路中的放大器使用的演算法是基於無差拍控制，其可以實現快速的動態響應，從而使功率硬體迴路模擬更接近真實的情況。
2. 功率裝置與模擬系統之間為諾頓-戴維寧電路的介面模型，而不是電壓-電流的介面模型，更適合實際的應用。
功率硬體迴路的結果與離線模擬結果相比，非常的吻合，證明了該方法的有效性。

Power hardware in the loop simulation (PHIL) is a real-time simulation allowing a real power device to interact with a simulated power system. With ever increase demand of interfacing renewable energy based generators (REBG) to the main grid, PHIL simulation has gained high attention as to the close-to-real phoneoma can be achieved. Hence, the impact of REBGs on the grid can be accurately predicted via PHIL.
In the thesis, a PHIL setup for a PV system interfacing a DC microgrid is carried out. The PHIL configuration used in this thesis has the attributes different from the conventional PHIL:
1. The control algorithm employed in the amplifier of the PHIL is based on dead-beat control. This allows fast dynamic response, .10312 PHIL simulation closer to the real phoneoma.
2. The interfacing algorithm between power device and simulated system is Norton-Thevenin circuit rather then voltage-current circuit, which is more suitable for practical implementation.
The PHIL results are in close agreement with those of offline simulation, justifying the validity of the proposed method.
