由於太陽光電發電併網滲透率在未來將增加，為避免因大量太陽光電發電併網後，造成配電饋線電壓劇烈變動及發生負載潮流過載。本論文應用配電系統模擬(DSS)分析軟體，模擬分析各種太陽光電併網情境，在不違反電壓變動率限制條件下，評估太陽光電發電系統最大併網容量。為評估太陽光電可併網之最大容量，選擇電力公司一條配電饋線，進行衝擊模擬分析。藉由配電監控及資料擷取(SCADA)系統，獲得太陽光電系統每日發電量紀錄；配電饋線匯流排負載資料，亦可由配電自動化系統(DAS)獲得。太陽光電發電系統注入電網之實功，配電饋線線路阻抗，將應用於DSS模擬分析，進行配電饋線責任分界點(PCC)電壓變動率計算。數值分析結果顯示，依據太陽能發電系統發電量變動與配電饋線尖離峰負載變化，藉由執行DSS衝擊分析，將可獲得太陽光電併網之最大容量及故障電流。

For the penetration of PV power generation into distribution systems will be increased dramatically in the future, the impact analysis of distribution feeders is important for avoiding voltage dramatic fluctuation and mitigating power flow overloading due to large amounts photovoltaic (PV) power generation incorporate with distribution systems. In this thesis, a distribution system simulator (DSS) is applied for evaluation the amount of PV power generation in various scenarios condition so that the maximum amount PV power generation incorporate with distribution systems under non-violation constrain can be obtained. To incorporate PV power generation in maximum amount, a Taipower distribution feeder with large PV installation is selected for computer simulation. Daily loading unbalance is determined by analyzing PV power generation recorded by the SCADA system and by constructing daily power load profiles based on distribution automation system (DAS) data. The injection real power of PV system and the line impedance of distribution feeders are used to simulate the voltage fluctuation in the point of common coupling (PCC) of test feeder. Computer simulations showed that the maximum value of PV power generation and fault current can be obtained in distribution feeders with large capacity of PV installation by executing DSS according to the variation of solar energy and power loading of study feeders.
