基于新能源气候响应能力分析的交直流混联电网优化设计
Hybrid AC/DC transmission network optimization design based on climate response analysis of renewable energy
摘要
Abstract
Long-term climate variability increases the uncertainty of renewable energy output fluctuations in future power systems with high renewable penetration,leading to risks of sustained supply-demand imbalances.Addressing the current insufficiency in grid design practices where climate factors are rarely incorporated,this study first develops a long short-term memory(LSTM)neural network model to capture the response characteristics of renewable energy to meteorologi-cal conditions,utilizing historical generation data and high-resolution weather datasets.On this basis,a mathematical optimization model tailored for regional hybrid alternating current(AC)/direct current(DC)grid design is constructed to evaluate transmission expansion strategies over multi-year time horizons.Furthermore,climate scenario data from the Coupled Model Intercomparison Project Phase 6(CMIP6)are employed to test the methodology through case studies.The results show that under low-emission scenarios,the demand for new transmission corridors to maintain supply-demand balance is relatively limited.In contrast,high-emission scenarios require more intra-and inter-provincial trans-mission expansion to alleviate renewable energy shortfalls during certain critical periods.关键词
