摘要:
      为适应未来配电网可能出现的交直流混合拓扑形态,提出了基于二阶锥规划的交直流主动配电网多时段日前优化调度模型。该模型以购电费用和弃光弃风惩罚费用之和最小作为目标函数,通过分布式电源有功无功调节、容抗器投切、储能充放电功率调节、电压源换流器无功调节及配电网动态重构等多种主动管理措施实现主动配电网有功-无功联合优化,消除潮流及电压越限,解决高比例分布式电源接入交直流主动配电网后的日前优化调度问题。修正50节点算例的分析验证了所提模型的正确性。
Abstract:
      In order to meet the possible appearance of AC-DC hybrid topology in the future distribution network, this article proposes a multi-period optimal scheduling model for AC-DC active distribution network which based on second-order cone programming. Taking the minimum cost of power purchase and the penalty of DGs curtailment as the objective function, the proposed model aims at realizing the joint optimization of active-reactive power through various active management measures, such as the adjustment of DG, CB, ESS and VSC and dynamic reconfiguration of distribution network. In addition, it overcomes over-limit voltage and power flow and solves the optimal scheduling problem in AC-DC active distribution network with high penetration of DGs. Finally, the correctness of the proposed model is verified by a 50-bus case.
