摘要:	我國政府設定2050淨零排放目標，電力部門去碳化為關鍵重點之一，也持續帶動再生能源快速發展及電網儲能設備增長。另一方面，交通和工業領域低碳化，促使負載型態變得多元且具隨機性。面對電網發、用電的高度不確定性，電力系統管理複雜性因而增加。電網的整合與調度除須結合先進的資通訊和數據技術，亦需仰賴多種時間長度的彈性資源支持，以提升系統的效率與穩定性。虛擬電廠可聚合各種分散式電源，利用先進的資通訊技術和最佳化演算法對分散式電源進行適當的協調和管理。在確保利害關係人的滿意度與最適利益的情況下，允許參與者因應市場價格訊號和/或電網運作狀況提供用戶側彈性資源，進而提高電力系統在淨零轉型過程中的可靠度與穩定度，被廣泛認為是電力系統脫碳所需的關鍵要素。本博士論文以單一電力用戶滿足自身用電目標為始，探討分散式電源投資評估與運轉排程最佳化模型與方法；接著分析虛擬電廠在國內現行與未來電力市場架構下的角色與定位，研究虛擬電廠個別用戶資源調查、組成評估、及參與各式電力市場與方案機制的操作模型及成效評估工具。共計發展三種虛擬電廠最佳化能源管理模型，並與其他四種已知模型進行比較分析。各模型皆選用通用性的數學方法與程式化軟體，並運用國內真實案例數據進行模擬研究，研究結果顯示可分別適用於解決相關對應問題。面對我國電力自由化發展仍處剛起步的階段，為加速市場交易的活絡及擴大電力經濟市場參與涵容性，期本博士論文可提供投資人與市場利害關係人一系列具有學術與實務價值的虛擬電廠操作工具，有助於加速虛擬電廠的推廣，擴大用戶側資源的調度與活用，並為政策制定者提供可行建議，提升市場運行效率，引領我國朝向穩健開放更多元的電力市場，順利達成2050淨零轉型目標。;In pursuit of the 2050 net-zero emissions target set by Taiwan, decarbonization of the energy department has emerged as a critical priority. This objective has driven the rapid development of renewable energy within the power grid. Concurrently, low-carbon transitions in the transportation and industrial sectors have introduced diverse and stochastic load patterns. As uncertainty in power generation and consumption increases, managing power systems has become increasingly complex. Addressing these challenges requires the integration of advanced information and communication technologies (ICT), data analytics, and flexible resources across varying timeframes to enhance system efficiency and stability. Virtual power plants (VPPs) represent a key solution by aggregating diverse distributed energy resources (DERs) and utilizing advanced ICT and optimization algorithms for their coordination and management. By ensuring stakeholder satisfaction and optimizing benefits, VPPs enable participants to respond effectively to market price signals and/or grid operating conditions, providing demand-side flexibility. This capability significantly enhances the reliability and stability of the power system during the net-zero transition and is widely recognized as a critical element of power system decarbonization. This dissertation begins with the exploration of investment evaluation and optimal scheduling models and methods for DERs, aimed at enabling an individual electricity user to meet their own energy consumption goals. Subsequently, the role and positioning of VPPs are analyzed under the current and future electricity market structures in Taiwan. The research investigates operational models and performance evaluation tools for resource surveys, composition assessment, and participation in various electricity markets and program mechanisms by individual users within a VPP. Three energy management optimization models for VPPs are developed and compared with four existing models. All models employ universal mathematical methods and programming software, utilizing real-world case data for simulation studies, and are tailored to address corresponding problems effectively. As Taiwan′s electricity market liberalization is still in its early stages, this dissertation aims to provide investors and market stakeholders with a series of VPP operational models and tools that hold both academic and practical value. These models and tools can help enhance the dispatch and utilization of demand-side resources, offering actionable insights for policymakers to improve market efficiency. Ultimately, this supports the smooth achievement of Taiwan′s 2050 net-zero transition goals.
