Consideration of Dual-layer Hybrid Energy Storage Capacity Configuration Accounting for Photovoltaic Forecasting Errors and Grid Fluctuation Rates
摘要
Abstract
To meet grid connection requirements and ensure robust operation of the power system,a two-layer opti-mization model was proposed with objectives of reducing PV prediction errors,smoothing grid-connected power fluc-tuations,and minimizing annual equivalent costs.The upper-layer planning aimed to minimize annual equivalent costs,which included system investment,equipment replacement,maintenance costs,and carbon emission benefit costs.To improve system economic efficiency,a fuzzy genetic particle swarm algorithm was developed to optimize and analyze the model.In the lower-layer planning,the model aimed to minimize prediction errors and grid connec-tion volatility.Based on distinct characteristics of supercapacitors and batteries,a charging-discharging power allo-cation strategy was constructed to enhance system response speed and extend battery cycle life.A solver was em-ployed for control implementation to achieve PV prediction error compensation and PV output fluctuation smoot-hing.Finally,a model evaluation index function was established based on the proposed framework,with a PV pow-er plant serving as a case study.Results demonstrated that the proposed algorithm exhibited faster convergence speed and superior optimization capability in this model.The RMSE and MAPE of prediction errors were reduced by 99.95%and 99.97%respectively,while the maximum grid connection fluctuation rate decreased by 96.08%after optimization.These findings verified the effectiveness and practicality of the proposed strategy.关键词
