摘要: | 本計畫為達成微電網智慧電能控制與管理之目與提升分散式發電系統使用效率,將設計一以工業級電腦(Industrial PC, IPC)為基礎之微電網控制器,並以RS485作為分散式發電系統,如風力發電機(Wind Turbine Generator, WTG)及儲能系統,與IPC間之資料傳輸。待電力資訊收集與處理完畢後將微電網控制器之資訊傳送至各微電網分散式發電系統系統作有效的能源分配與管理。同時本計畫將以數位信號處理器TMS230F28035發展磷酸鋰鐵電池儲能系統及採用TSK機率模糊類神經網路(TSK-Type Probabilistic Fuzzy Neural Network, TSKPFNN)控制器來提升充、放電性能,再者藉由取得電池的相關資料,來進行電池殘餘電量(State of Charge, SOC)估測;另外也藉由儲能系統儲存多餘電力,而當市電斷電,且分散式發電系統又無法提供足夠的電力時,利用儲能系統來提供適當的電量給負載,並且當饋線發生電壓驟降時,可提供虛功率至系統上,補償饋線所引起之電壓下降,以達到低電壓穿越(Low Voltage Ride Through, LVRT)的能力。此外,本計畫也將發展太陽能發電系統,在控制的部分,將加入最大功率點追蹤(Maximum Power Point Tracking, MPPT),提升太陽能的發電效率。微電網控制部分,本計畫將完成微渦輪發電機(Micro Turbine Generation, MTG)、風力發電機、儲能系統與負載併網、最大功率追蹤及電能管理等功能之驗證,並發展整合再生能源之電能管理系統(Energy Management System, EMS)。最後將藉由IEEE1547及UL1741所提供之測試方式以測試所發展之併網型分散式發電系統,使其具備孤島運轉之相關功能,並能符合相關之併聯標準與規範。 ; The objective of this project is to manage and control microgrid using intelligent technologies and to improve the efficiency of power management for the distributed generation systems (DGs). An industrial PC (IPC)-based microgrid controller will be designed and RS485 will be adopted for internal data transmission between the DGs (e.g. wind turbine generator (WTG) and storage system) and the IPC. After the power information is collected and managed completely, the data will be sent to the DGs for the efficient power management of the microgrid system. Moreover, in order to improve the charging/discharging efficiency, the LiFePO4 storage system based on TMS320F28035 digital signal processor (DSP) adopted TSK-type probabilistic fuzzy neural network (TSKPFNN) controller will be designed. Then, the state of charge (SOC) will be developed using the collected information of the storage system. Furthermore, when the grid is disconnected and the DGs can’t provide enough power, the storage system will provide electric power to the load. When voltage sag occurs in the grid, the storage system will also feed reactive power to the grid to compensate the voltage dip to achieve low voltage ride through (LVRT). In addition, in order to achieve the best efficiency of photovoltaic (PV) system, a new maximum power point tracking (MPPT) will be developed. Additionally, the energy management system (EMS) will be developed for the control of microturbine generation (MTG), WTG and storage system, and to verify the MPPT and power management functions for the microgrid system. Finally, in order to possessing the function of islanding and meeting the relevant interconnection standards, this project will verify the developed grid-connected DGs by using the offered test methodology in IEEE1547 and UL1741. ; 研究期間 10201 ~ 10212 |
