摘要: |
为解决风力发电直接并网所产生的功率波动问题,提出了一种基于改进阿基米德优化算法融合自适应噪声完全集合经验模态分解(complete ensemble EMD with adaptive noise, CEEMDAN)的容量配置方法。采用由限幅与滑动平均结合的加权滤波算法平滑风电出力,同时减小平滑结果的滞后性,得到风电并网功率和混合储能系统(hybrid energy storage system, HESS)参考功率。为了合理分配HESS的内部功率,借助CEEMDAN分解HESS的参考功率,得到高低频分量。综合考虑HESS功率和容量、荷电状态(state of charge, SOC)与负荷缺点率等因素,构建以年综合成本最小为目标的容量优化配置模型并采用改进阿基米德优化算法求解。基于实际算例进行仿真分析,结果表明,与原始风电并网相比,HESS配置方案将波动率减少了13.538%,平滑度提高了16.057%。相较于传统单一储能平抑效果更加明显,减少了容量配置。同时,对比传统阿基米德优化算法节省了15.325%的投资成本。 |

Abstract: |
To address the problem of power fluctuations caused by direct grid connection of wind power, this paper proposes a capacity optimization algorithm based on improved Archimedes optimization algorithm with complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN). A weighted filtering algorithm, combining amplitude limiting and moving average, is used to smooth wind power output and reduce the lag in the smoothed signal, thus generating the reference power for grid-connected wind power and the hybrid energy storage system (HESS). To allocate HESS’s internal power, the reference power is decomposed into high- and low-frequency components using CEEMDAN. Taking into account factors such as HESS power and capacity, state of charge (SOC), and load defect rate, a capacity optimization model aiming at the minimum annual comprehensive cost is constructed and solved by improved Archimedes optimization algorithm. Simulation analysis based on real case data shows that, compared with the original grid-connected wind power, the proposed HESS configuration scheme reduces power fluctuation by 13.538% and increases smoothness by 16.057%. Compared with the traditional single energy storage, the proposed method achieves better fluctuation mitigation and reduces the required capacity. Moreover, it lowers investment cost by 15.325% compared to the conventional Archimedes optimization algorithm. |
