| 摘要: |
| 波动性电源的大规模接入，不仅造成电力系统运行调度困难，而且会影响其安全稳定运行。因此，通过配置储能装置来对并网功率进行平滑控制十分必要。基于一定配置容量的混合储能系统（HESS），提出一种用于大型风电场并网的最优控制方法。采用蓄电池和超级电容为储能介质，建立短期优化控制的动态模型，确立相应的控制目标和约束条件，并设计基于粒子群优化（PSO）的求解算法。仿真算例的结果表明该方法是正确、有效的。 |

| Abstract: |
| The large-scale integration of fluctuated power sources makes the operation and dispatch of power system difficult and impacts its secure and stable operation. Therefore the energy storage device is applied to smooth the grid-connecting power. An optimal control method is proposed for the grid-connected large-scale wind farm equipped with the HESS（Ｈybrid Ｅnergy Ｓtorage Ｓystem）. With the battery and super capacitor as the energy storage media，a dynamic model of short-term optimal control is built and the corresponding control objectives and constraints are determined. An algorithm based on PSO（Ｐarticle Ｓwarm Ｏptimization） is designed to solve the model. The result of a simulation case verifies the correctness and effectiveness of the proposed method. |
