論文概要:The energy transition is essential for achieving carbon neutrality. However, integrating renewable energy poses several technical and economic challenges, including ensuring economic viability and balancing the interests of supply and demand stakeholders. This study systematically addresses these challenges by examining the potential of green power purchase agreements (PPAs) to support power sector decarbonization. By designing a PPAs framework, focusing on both supply and demand-side perspectives, this research aims to establish a flexible, low-risk, and high-revenue strategy for the energy transition.
Chapter 1: Research Background and Purpose of This Study. This chapter established the context and highlights the potential of PPAs and innovative market-based solutions to power decarbonization.
Chapter 2: Literature Review. This chapter reviewes research on PPAs, optimization models, and machine learning in energy systems.
Chapter 3: Methodology. This chapter primarily introduces the construction of a financial model integrating PPAs, including energy optimization models and an energy market forecasting model.
Chapter 4: Techno-economic Analysis of Green Power Trading Model. The feasibility of a third-party ownership (TPO) model for rooftop PV adoption is evaluated.
Chapter 5: Develop A Forecasting Model for Short and Long-term Electricity Market. A Bayesian Optimization-based Convolutional Neural Network and Long Short-Term Memory (BO-CNN-LSTM) model is proposed for short and long-term electricity market forecasting, offering improved accuracy and insights into price drivers like demand and fuel costs.
Chapter 6: Analysis of Long-term RE100 Procurement Strategies for Typical Large Users. An innovative hybrid procurement strategy combining PPAs with Battery Energy Storage Systems (BESS) is introduced. The strategy optimized RES procurement for large users in long-term.
Chapter 7: Analysis of Urban-scale Power Decarbonization for Planners and Investors. This chapter proposed an optimized framework for urban-scale decarbonization, integrating RES, green hydrogen, and CCS.
Chapter 8: Conclusions and Prospect.
