Abstract

The increasing global demand for renewable energy necessitates accurate forecasting methods to optimize wind energy production, particularly in regions with varying climatic conditions. This study addresses this need by utilizing advanced deep learning techniques and Geographical Information Systems (GIS) to estimate the energy output of wind turbines. Specifically, it focuses on predicting the energy production of both horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs) using a combination of Markov and Cellular Automata-Markov (CA-Markov) models, alongside deep learning methods such as long short-term memory (LSTM), LSTM-Wavelet, and Support Vector Regression (SVR). Additionally, the study evaluates the energy output of each turbine type, factoring in their construction costs within the study area. The analysis reveals significant variations in energy output over time, with maximum values increasing from 85,017 Wh in 2000 to 166,050 Wh in 2020 in the northern region, while minimum outputs also rose significantly. Projections for 2030 suggest that approximately 17% of the northern region experience a substantial increase in wind power potential. Among the forecasting methods, the LSTM-Wavelet hybrid model demonstrated superior accuracy, surpassing the 90% threshold, primarily due to its effective handling of data instability and noise reduction. This study underscores the potential of using sophisticated modeling techniques to enhance wind energy forecasting, contributing to more efficient energy management in regions with high energy demand and limited resources.

利用 GIS 中的深度学习方法预测风力涡轮机的发电量:关于 HAWT 和 VAWT 的研究
全球对可再生能源的需求与日俱增,因此有必要采用精确的预测方法来优化风能生产,尤其是在气候条件各不相同的地区。本研究利用先进的深度学习技术和地理信息系统(GIS)来估算风力涡轮机的能量输出,从而满足了这一需求。具体来说,研究重点是利用马尔可夫模型和蜂窝自动机-马尔可夫(CA-Markov)模型,以及长短期记忆(LSTM)、LSTM-Wavelet 和支持向量回归(SVR)等深度学习方法,预测水平轴风力涡轮机(HAWT)和垂直轴风力涡轮机(VAWT)的发电量。此外,该研究还评估了每种涡轮机类型的能量输出,并将其在研究区域内的建造成本考虑在内。分析表明,随着时间的推移,能量输出有很大的变化,北部地区的最大值从 2000 年的 85,017 Wh 增加到 2020 年的 166,050 Wh,而最小输出也显著增加。对 2030 年的预测表明,北部地区约有 17% 的地区风力发电潜力将大幅增加。在各种预测方法中,LSTM-Wavelet 混合模型的准确率较高,超过了 90% 的临界值,这主要归功于它对数据不稳定性的有效处理和噪声的降低。这项研究强调了利用复杂建模技术加强风能预测的潜力,有助于在能源需求高而资源有限的地区进行更有效的能源管理。
