應用即時模擬技術於直流微電網模擬之分析

近年來隨著環保意識的抬頭，加上再生能源發電的技術逐漸成熟，使得再生能源占發電的比例日益增高，目前常見的再生能源多為太陽能和風力發電。再生能源結合附近的負載可以構成一個微型電網，而微電網可提供特殊地區用電，或是當市電發生故障時可以持續供電。電腦模擬對於電力系統相關規畫與研究是必要的步驟，由於電力系統在建構及成本上往往需要長時間和大量金錢，因此若能在系統建立之前，先藉由模擬得知可能發生的狀況而對設計做修正，則能避免日後對實際系統造成重大損失。因此這對於微電網的相關控制是相當重要的，像:綠能源件模型設置與驗證、微電網在各情況下的運轉情形控制與驗證或實際應用於微電網的硬體測試。本論文主要為架設一直流380-V的微電網進行相關模擬，其中包含光電系統3.78 kW、風力發電2.5kW、燃料電池 5kW，以及48V 500Ah之電池儲能系統。此外，結合即時模擬技術，克服離線模擬相關限制(如：計算時間過長、數值震盪與缺乏與硬體互動能力)，並比較即時模擬和離線模擬的精確性和計算時間。

Along with the environmental concern and the advance of technology of renewable energy generation, the proportion of renewable energy in energy power systems is increasing. The most commonly seen renewable energy resources are photovoltaic(PV) and wind turbines.Microgrid studies have attracted much attention in recent yeays. Microgirds consist of several renewable sources (or distributed generations) and local loads, which provide the solution to provide premium quality of power to remote or specified area. It is necessary to perform computer simulation for power system planning and study. Establishing the electrical power systems takes long time and costly money. Therefore, before the actual system is built, all possible responses of the system should be known and then the design can be modified to avoid negative impact of the system. As a result, computer simulation is important for the development and study of the micogrid, such as modeling and verification of renewable energy resources, testing under possible scenario, or testing the real hardware. The main purposes of the thesis are that building models of renewable energy sources, optimal operation strategy and energy management system. Moreover, in order to overcome limitations of off-line simulations (such as: time-consuming jobs, numerical oscillation, and lack the capability of interfacing with real devices), real-time simulation techniques are needed. Then, compartions between the computed-time and accuracy of off-line simulations with these of real-time simulations are performed.
