本計畫主要目標為利用Matlab\Simulink模擬分散型區域能源之調度能力與研究，為達此目的將依據核能所微電網系統為基礎建立模組，其微電網系統包含太陽能發電系統、儲能系統與負載。微電網控制法則採主從(Master/Slave)模式，儲能系統當成主要系統，在併網操作時控制其實、虛功率輸出，當市電故障時，儲能系統轉換成控制電壓、頻率控制以維持微電網電壓與頻率，而太陽能發電系統當成從系統，在併網或孤島運轉時皆控制其實、虛功率輸出。本計畫將分析市電電壓或頻率異常時，微電網系統整體之暫態響應，此外，將討量儲能系統在不同虛擬慣量下，探討微電網與市電間的保護電驛動作，分析微電網轉成孤島之電壓與頻率的響應。最後將提出再生能源機組之調頻能力及微電網之卸載建議。 ;The objective of this project is to research and analyze the energy dispatch of distributed area via Matlab\Simulink software. To achieve the purpose, the microgrid system of the institute of Nuclear Energy Research (INER), including PV system, storage system and loads, is adopted to established the simulation models. Moreover, the master/slave control algorithm is adopted in the microgrid. The storage system which is considered as the master unit and is adopted to control the active power and the reactive power outputs (P/Q control) in grid-connected mode and the voltage and the frequency of the microgrid (V/f control) in islanded mode. Furthermore, the PV system is considered as the slave unit to implement P/Q control in both grid-connected and islanded modes. In addition, when the power grid and frequency are abnormal, the transient responses of the microgrid system will be investigated in this project. Additionally, the action of the protection relay between the power grid and microgrid system, which the storage system is with different virtual inertia, will be studied. Finally, some suggestion for energy dispatch of distributed generators and the load shedding of microgrid will be provided.
