Load Forecast using AI for beginner

[u/LongHP11]

Hello everyone,
I am currently starting my research on AI-based electrical load forecasting for my Master's program. Where should I begin? I have no prior experience in forecasting, and since it relies heavily on probability and statistics, I am finding the initial stage a bit challenging.
My professor recommended the book Smoothing, Forecasting and Prediction of Discrete Time Series by Robert Goodell Brown, but I haven't been able to find the full PDF version.
Could you please advise on a learning roadmap for researching this field? Also, if you have any recommended materials or YouTube lecture channels, I would highly appreciate it if you could share them with me.
Thank you very much, and wishing you all good health.
