摘要: | 本論文提出一主動式電力調節器具有實虛功補償功能,並將其應用在微電網運轉與控制,本研究建立之模擬平台包括數個以分散式電源組成之微電網,兩微電網間以主動式電力調節器連接,實虛功補償策略則以垂降控制(Droop control method)為基礎,並加入磁滯區間以減少開關切換次數,另外還要對實虛功補償策略以及控制器進行穩定度分析,最後對於多微電網補償進行分析,討論如何分配補償比例,以達到頻率變動最小化,本文用 MATLAB/Simulink套裝軟體來模擬驗證,由模擬結果評估微電網控制之成效。 This thesis presents a novel active power conditioner, which has active and reactive power compensation functions, applied in micro-grid operation and control. In this study, the simulation micro-grids assumes consisting of a number of distributed genertaors. We apply the active power conditioner to connect two micro-grids. The active and reactive power compensation sceme is based on the droop control method and the hysteresis loop is added to reduce the number of count of switching. We also analyze the stability of the proposed controller and droop control compensation scheme. Finally,we discuss more microgrids compensation.Analysis how to allocate compensation ratio to achieve frequency variation is minimized.The performance evaluation of assumed micro-grid and the control schemes are conducted with a popular software package, MATLAB/Simulink. Some engineering insights from simulation results are obtained in this Thesis. |
