本研究旨在開發小區域互助式太陽光發電系統(HyPV-net)的聯網技術。本研究以混合式太陽光發電系統(HyPV, Hybrid PV system)個體戶為基礎,藉由互助式電網結構與聯網控制技術,透過中央控制系統(CCU, Central Control Unit)與HyPV溝通,進行交流電力輸出的互相調度,當某一HyPV個體戶有多餘太陽電力時,便支援其他HyPV個體戶,以提升太陽光發電系統之整體性能與經濟效益。本研究開發小區域互助式太陽光發電系統模擬分析軟體,進行長期性能分析以及系統設計探討,並實地架設一個二元互助式系統進行實地聯網測試驗證。
A networking technique for solar PV power co-sharing in a micro-grid composed of several hybrid solar PV systems (HyPVs) with limited battery storage, called “HyPV-net”, was developed. A power switching control was used to distribute the solar PV power between individual HyPVs. Excess solar PV power in an individual HyPV at low load power consumption will be transmitted to its neighbor HyPV through a central control unit (CCU) via ac power line. This will increase the PV power generation of the grid and improve the economy of the system. A long-term system performance simulation of HyPV-net for system design was carried out. A HyPV-net with two HyPVs was built and tested to measure its performance and verify the simulation results.
