發電自用太陽能系統研發

Abstract

本研究旨在研發不回售市電的太陽能光電系統，簡化舊有大瓦數型控制器，降低成本並改良系統控制與通訊軟硬體，提高系統穩定性與可靠度。搭配電力調度控制器以互聯的方式將個體戶多餘電力賣電至其他個體戶，提升整體太陽能發電效益。另改以使用雙向併網型逆變器與搭配防逆送電技術，以電熱器做為儲熱裝置，研發具有尖載放電與智能供熱功能的雙儲能併網型系統。

The research focuses on the development of solar PV system for self-consumption without selling electricity back to grid. We simplify the hardware of old controller, lower the cost and improve the software and hardware of control and communication, to enhance the system stability. Combined with CCU, one system can support its electricity for another system in binary-connection, to improve the power generating efficiency of the overall system. Besides, we use microinverter with anti-reverse-current technology and electric water heater to develop the on-grid PV system with dual-energy sources, having the advantage of peak-load discharge and intelligent supply of hot water.
