区块链架构下风光储电站超短期功率预测方法
Fusion Method for Blockchain-based Cyber-physical System of Wind-solar-storage Power Stations and Ultra-short-term Power Prediction
摘要
Abstract
The power prediction of wind-solar-storage power stations is fundamental to both the dispatch of the stations themselves and the dispatch of the larger power grid.To ensure the prediction process,the cyber-physical system(CPS)that underpins this pro-cess requires stronger security.Power forecasts to meet dispatch requirements need to ensure high accuracy,high-frequency up-dates,short time scales,and multiple time scales.In this paper,a blockchain-based ultra-short-term power prediction method for wind-solar-storage power stations is proposed.The blockchain-based two-layer architecture of wind-solar-storage power station cyber-physical system can weaken the dependence on the physical topology of the storage power station and eliminate the vulnerability when responding to attacks.The improved spatiotemporal graph convolutional network algorithm can increase parameter scale flexi-bility and inter-parameter correlation to improve prediction accuracy.Combining these two in a blockchain smart contract,forming a blockchain-based ultra-short-term power prediction method for wind-solar-storage power stations,ensures the security of the predic-tion process and the prediction results.At the end,the proposed method is validated through case studies,demonstrating its effec-tiveness.The average error in electricity load forecasting is reduced by at least 1.22%,the average error in heat load forecasting is reduced by at least 4.70%,the average error in cooling load forecasting is reduced by at least 1.60%,and the average absolute error in renewable energy output forecasting is reduced by at least 2.17%.关键词
