| 摘要: |
| 同时计及分时电价、经逆变器接入配电网的分布式电源有功与无功调节能力、调节设备动作代价及电缆对地分布电容电流，以购电与调节设备动作总费用最小为目标函数，考虑运行约束，基于支路潮流方程构建电缆配电网有功、无功多时段二阶段混合整数二阶锥鲁棒优化模型，并提出一种基于割平面的主、次问题交替迭代求解方法。不同于现有列与约束生成算法，利用所提方法求解主问题时无需增加新的变量与约束条件，利用所提方法求解次问题时只需针对每个时段进行求解，极大降低了求解复杂度与所需计算机内存。4节点、IEEE 33节点与P&G 69节点配电网算例仿真结果验证了所提方法的性能。 |

| Abstract: |
| Simultaneously considering the time-of-use price, the active and reactive power regulation capabi-lity of distributed generators accessed to distribution network with inverters, the action cost of regulation equipment and the distributed capacitive current of cables to ground, a multi-period two-stage mixed-integer second-order conic programming robust optimal model of active and reactive power for distribution network is built based on branch power flow equations, which takes the minimum total cost of power purchase and regulation equipment action as the objective function and considers the operation constraints. An alternative iteration solution method of primary and secondary problems based on cutting plane is proposed. Different from the existing column and constraint generation algorithm, the proposed method does not need to add new variables and constraints when solving the primary problem, and only needs to solve in each period when solving the secondary problem, which extremely reduces the solution complexity and computer memory required. The case simulative results of 4-bus, IEEE 33-bus and P&G 69-bus systems verify the performance of the proposed method. |
