摘  要:智能软开关(soft normally open point,SNOP)是一种取代传统联络开关的新型智能配电装置,SNOP的应用将极大地提高配电系统运行的灵活性和可控性。但考虑到接入和运行成本,未来的配电系统运行可能要面临同时考虑SNOP和联络开关的情形。首先,研究联络开关和SNOP并存时配电网运行的时序优化模型,该问题在数学上属于混合整数非线性优化问题;进而提出一种基于模拟退火(simulated annealing,SA)和锥优化(conic programming,CP)的混合优化算法进行求解,算法利用SA实现开关状态的快速求解,利用CP实现SNOP传输功率的准确计算,能够实现大规模混合整数非线性优化问题的快速、准确求解,并满足时序优化问题的计算需求。最后,在IEEE 33节点算例上,对所提出的运行优化模型和求解算法进行分析和验证。Soft normally open point (SNOP) refers to a novel type power electronic device installed in place of a normally-open point, also called tie switch, in a medium- voltage distribution network. The ap, plication of SNOP will greatly promote the flexibility and controllability of the distribution network. Considering the higher investment and operation cost of SNOP, both tie switch and SNOP should be taken into account as a whole in the operation optimization problem of distribution system in the future. Firstly, the time-series optimization model of distribution network operation with SNOP and tie switch was proposed, which belongs to a mixed integer nonlinear problem. Secondly, combining the simulated annealing method with the conic programming, this paper proposed a hybrid optimization algorithm, which used simulated annealing method to solve the switch states and conic programming to solve the power of SNOP. The hybrid optimization algorithm can solve large-scale mixed-integer nonlinear optimization problem accurately and rapidly, which also satisfies the demand of time-series optimization problems. Finally, the optimization model and the hybrid optimization algorithm were analyzed and verified on IEEE 33-node test feeder.
