| 摘要: |
| 动态风电穿透功率极限(DWPPL)代表黑启动过程中系统在不同恢复时段对风电的接纳能力，其成功求解可以指导风电在系统恢复过程中的有序接入，进而使系统依靠风电启动功率小、启动速度快的优势，加快系统恢复进程。为了更加准确地求解DWPPL，建立计及系统暂态安全约束的DWPPL非线性整数规划模型，该模型采用二元表的方式统一描述了各暂态安全约束；提出基于纵横交叉优化算法和PSD-BPA仿真的DWPPL求解方法。针对含风电的IEEE 39节点系统中某具体黑启动方案，求解了各时段的DWPPL并验证了算法的优越性；在PSD-BPA上仿真验证了所求DWPPL的正确性和考虑系统暂态安全的必要性。 |

| Abstract: |
| DWPPL(Dynamic Wind Power Penetration Limit) represents the maximum wind power accommodation capability of power system at different restoration periods in the process of black start, the solution of which can guide the ordered access of wind power in the process of system recovery, and thus accelerate the recovery process relying on the advantages of small startup power and fast startup speed of wind power. In order to solve the DWPPL more accurately, the nonlinear integer programming model of DWPPL with the consideration of system transient security constraints is established, which uses two element table to describe the transient security constraints. A method based on crisscross optimization algorithm and PSD-BPA simulation is proposed for solving DWPPL. Aiming at a specific blackstart scheme of the IEEE 39-bus system with wind power, the DWPPL of each period is solved and the superiority of the algorithm is verified. The correctness of the obtained DWPPL and the necessity of considering the system transient safety are verified by the simulation on PSD-BPA. |
