含儲能系統住宅型太陽光電發電系統之分析及實例探討

本論文旨在分析及探討含蓄電池儲能系統之市電併聯型太陽光電發電系統，利用 HOMER Energy套裝軟體對小型智慧型電網模擬與實測驗證，針對台灣北部地區住家安裝4.88kWp太陽光電發電系統及2.4kWh儲能系統，採用HOMER Energy套裝軟體及其內建的氣象資料，探討一般家庭設置太陽光電發電系統加裝儲能系統，在正常情形下的購、售電分配及負載間之電能調度，藉以瞭解系統最佳配置之淨現值成本、每度電用電成本及投資成本所需之回收年限。本文之研究可提供民眾欲安裝住家型太陽光電發電系統時最佳配置及設計決策之參考。以桃園某住家為例，探討自用的發電系統，依現場環境估算可安裝的太陽光電發電系統及蓄電池容量，若市電停電，太陽光電及儲能系統仍可繼續運作，以達不斷電系統的功能。本文研究加入現行能源成本及環境參數，利用HOMER Energy套裝軟體實施模擬，可提供一般設置者參考。

This paper aims to analyze and case study of residential photovoltaic power generation system with battery energy storage system. For the installation of 4.88kWp photovoltaic power generation system and 2.4kWH energy storage system in northern Taiwan, the HOMER Energy software package and built-in meteorological data were used to explore the installation of energy storage system in the general residential photovoltaic power generation system. Under normal condition, taking a home in Taoyuan as an example, we discuss the self-use power generation system and estimate the installed solar photovoltaic power generation system and battery capacity according to the site environment. If the utility power is cut off, the photovoltaic energy and battery storage energy can continue to supply the series load to achieve the function of the uninterruptible power system. This paper studies the addition of current energy costs and environmental parameters, using the HOMER Energy software package to implement simulations, which can provide a general setter reference.
