| 摘要: |
| 电池储能系统(BESS)平滑功率波动问题是一个高维度、多约束的非线性规划问题。为了更好地求解该问题，提出了一种基于非线性互补牛顿算法的BESS平滑策略。将储能系统平滑问题中的最优性条件转化为非线性方程组，进而将求解原问题转化为求解非线性方程组，并采用牛顿法进行求解。算例结果表明，该方法能够有效地追踪目标函数，从而平滑风功率波动，且具备连续平滑能力。 |

| Abstract: |
| Smoothing power fluctuations using a battery energy storage system is a nonlinear programming problem with huge dimensions and multiple constraints. To obtain a more tractable optimal solution, a smoothing strategy of battery energy storage system based on nonlinear complementary Newton method is proposed, in which the optimality conditions of smoothing problem are transformed into nonlinear equations. As a result, the original problem is reformulated as a set of nonlinear equations, which can be solved by Newton method. The case results demonstrate that the proposed method is effective in smoothing wind power fluctuations and is capable of continuous smoothing. |
