摘要: |
传统配电网规划通常是先规划再进行可靠性的校核,难以将可靠性校核结果反馈以有效修正网架规划方案,因此需要建立考虑配电网可靠性的规划方法。而随着配电网发展,移动和固定式储能得到广泛应用。通过多类型储能的优化配置,可在故障发生时维持关键负荷的供电,提高城市配电网可靠性。首先,采用了一种基于故障时序逻辑的可靠性指标解析表达方法,将可靠性指标约束嵌入传统配电网规划模型。然后,在运行约束中考虑移动储能车以及固定式储能参与恢复供电的故障时序逻辑,建立改进的配电网规划模型。该模型实现了计及移动和固定储能对可靠性影响的配电网规划,可采用混合整数线性规划求解器求解。最后,通过24节点实际配电网算例证明了所提方法的有效性。 |

Abstract: |
Traditional distribution network planning usually first plans and then checks reliability. It is difficult to feed back the reliability check results to effectively correct the grid planning scheme. Therefore, it is necessary to establish a planning method considering the reliability of the distribution network. As the distribution network develops, mobile and fixed energy storage are widely used. Through the optimal configuration of multiple types of energy storage, the power supply of key loads can be maintained when faults occur, and the reliability of the urban distribution network can be improved. Therefore, this paper first adopts an analytical expression method for a reliability index based on fault timing logic. It embeds the reliability index constraint into the traditional distribution network planning model. Then, an improved planning model is established by considering the fault timing logic of mobile energy storage vehicles and fixed energy storage participating in the restoration of power supply in the operational constraints. The model realizes the distribution network planning considering the influence of mobile and fixed energy storage on reliability. It can be solved by a mixed integer linear programming solver. Finally, the effectiveness of the proposed method is proved by a 24-node actual distribution network example. |
