摘要 从波动平抑效果与平抑成本两个角度,对3种用于风功率波动平抑的电池储能系统(BESS)运行策略进行了对比分析。3种运行策略分别为:BESS统一运行、充放电状态随机切换;BESS分组运行、充放电状态同步切换与BESS分组运行、充放电状态异步切换。在考虑风功率预测误差随机特性的基础上,采用序贯蒙特卡洛模拟技术对上述3种策略下的BESS运行进行了模拟。基于模拟结果,在对波动平抑效果进行评估的同时,依据BESS总投资成本和电池循环寿命损耗对波动平抑成本进行估算。对比分析表明:BESS分组运行、充放电状态异步切换策略可实现波动平抑效果与平抑成本间的有效折衷,显著优于其它策略。 From the angles of both mitigating wind power fluctuations and operation costs,we comparatively analyzed the operational strategies of battery energy storage systems(BESS)which are designed to mitigate wind power fluctuations.Three different operational strategies for the BESS are as follows:(a)operating in whole and alternating charging/discharging state stochastically,(b)operating independently and alternating charging/discharging states synchronously,(c)operating independently and alternating charging/discharging states asynchronously.The Sequential Monte Carlo simulation technology(SMCST)was adopted to simulate operations of the BESS in different strategies with considerations of random predicting errors on wind power.Based on simulation results,performances on mitigating wind power fluctuations were evaluated.In addition,costs of the BESS consumed for mitigating wind power fluctuations were estimated according to investment costs and circle lift depletion of the BESS.Comparative analyses indicate that the strategy of operating independently and alternating charging/discharging states asynchronously is the best as it can compromise the mitigating performances of wind power fluctuation and mitigating costs.
