隨著基於可再生能源的發電裝置(Renewable energy based gener-ators, REBG)連接於主電網的需求增加，電力硬體迴路(Power hardware in the loop, PHIL)辦演了一個不可或缺的角色。電力硬體迴路模擬是一種即時模擬架構，可比傳統的模擬達到更貼近實際情形，因此可以透過電力硬體迴路模擬準確的預測可再生能源發電裝置對電網造成的影響。然而在PHIL中，電壓電流訊號在即時模擬器與硬體間的傳輸和疊代的過程中需要一段時間的處理，因此在本文中除了會進行交流電網的PHIL設置外，還會將Nelder-Mead演算法帶入到PHIL的設置當中。

With the increasing demand for renewable energy based generator (REBGs) to
be connected to the main grid, Power-hardware-in-the-loop simulation has played
an indispensable role. PHIL simulation is a real-time simulation framework that can
simulate a much more realistic phenomenon than traditional simulation, so it can
accurately predict the impact of renewable energy power generation devices on the
grid.
However, in PHIL, the voltage and current signals need to be processed for a period
of time for data transmission via iteration between the real simulator and the
hardware. Therefore, in this paper, the Nelder-Mead algorithms are carried over to
speed up this process.
