本論文研究電力市場與分析電業自由化，本研究使用Power World Simulator來建立IEEE 14-bus的測試系統，在此系統上進行測試和驗證，系統的負載設定為住宅、商業及工業用之典型全日負載，進行最佳的電力潮流分析，以最低的成本決定發電機的調度，同時滿足系統限制條件，藉由軟體的線性編程方法來尋找最佳求解方法，使參與者獲得最大利潤。其次，本論文將發電成本最小化為單一目標的傳統最佳電力潮流，修改為以社會福利最大化為目標，將售電業者與購電業者的利益同時加入到求解目標，可以提供電業市場更多的商機，營造出買賣方雙贏的局面。最後，本論文對社會福利最大化的競價結果進行穩定度分析，測試不同故障所造成的擾動對系統的影響，用以確保在系統規則改變後仍可保持系統穩定性。本論文的模擬結果將提供給台灣未來電力自由化擬定制度作為參考，提出自由市場機制及其擴充將可充分確保經濟最佳化原則、市場公平合理的運作及維持系統穩定調度的目標。

The power market is studied and the feasibility of power industry liberalization is analyzed in this thesis. Power World Simulator is used to build an IEEE 14-bus test system in this thesis. This system is also tested and verified. The system load is set to a typical full-day load for residential, commercial and industrial use. The optimal power flow (OPF) is performed and analyzed to determine generator dispatch at the lowest cost, and meet system constraints. The Linear Programming Optimal Power Flow (LP OPF) of the software is used to find the optimal solution method to maximize the profit of the power system. Next, this thesis minimizes the cost of generating electricity to a single target, the traditional optimal power flow, and revises it to maximize social welfare. The interests of both electricity sellers and electricity purchasers are added to the solution goal. It can provide more business opportunities in the power market and create a win-win situation for buyers and sellers. Finally, the stability of the social welfare optimal system analyzed in this thesis. The impact of the disturbance caused by different faults on the system is tested to ensure that the system stability can be maintained after the system rules are changed. The simulation results of this thesis will be provided to Taiwan's future power liberalization planning as a reference. Proposing a free market mechanism and its expansion will fully ensure the principle of economic optimization and fair and reasonable operation of the market. The goal of stable system scheduling is also maintained.
