基于风电功率预测的复合储能超前优化控制策略
An Optimal Look-ahead Control Strategy for Hybrid Energy Storage System Based on Wind Power Prediction
摘要
Abstract
With continuously increased accuracy and reliability,wind power prediction is introduced into the control process of hybrid energy storage system (HESS),and an optimal look-ahead control strategy for HESS is proposed.Firstly,the section length of predicted information is confirmed according to the probability distribution of contiguous charge and discharge time section length,and then the look-ahead time section is determined.Secondly,considering the dominant factors that influence the HESS efficiency,an efficient charge and discharge strategy for HESS is developed.Based on this,an optimization model under the synchronous starting of storage media of HESS is constructed,taking minimum-variance of state of charge (SOC) offset as objective function and considers the constraint conditions on charge/discharge power and HESS capacity,then the coordinated control model for next look-ahead time section is determined.Finally,the steps of algorithm solution are given. The analysis of actual wind farm power data shows that the method proposed is efficient in the HESS control with practical application value.关键词
