Slope Control Method with Variable Coefficients of Battery Energy Storage System for Smoothing Photovoltaic Power Fluctuation
摘要
Abstract
In order to improve the ability of battery energy storage system BESS to smooth photovoltaic PV power fluctuation a slope control method with variable coefficients based on ultra-short term power prediction is proposed.On the basis of the slope control method two parameters for controlling the partition of state of charge SOC and four charge and discharge power regulation parameters are proposed.Then a smoothing strategy containing the above six variable coefficients and able to regulate SOC automatically is developed.The obj ective function is developed based on the ultra-short term PV power prediction.And a self-adaptive chaos particle swarm optimization algorithm is used to optimize the coefficients in real time realizing the coordinated optimization between the smoothing performance and SOC.Compared with the method with fixed coefficients the simulation results show that the control strategy is able to reduce the charge and discharge depth of BESS on the premise of ensured smoothing of power fluctuation.关键词
