摘要

智能软开关（SOP）具有较强的潮流控制能力，在配电网正常运行场景下和故障环境中均能有效发挥作用，在规划层面应兼顾其对于配电网供电可靠性与运行经济性提升所带来的综合收益。文中综合考虑了SOP接入对配电网供电可靠性和运行经济性的影响，建立了智能软开关规划模型；采用快速搜索和发现密度峰聚类方法对年负荷数据进行聚类，生成配电网典型运行场景以计算其对运行经济性的提升收益；采用基于关联约束的支路故障率计算方法，考虑线路电流负载率、节点电压以及线路长度对支路故障率的影响，生成动态预想故障集以计算供电可靠性收益；采用模拟退火与二阶锥规划相结合的混合算法对上述规划模型进行求解，最后，在PG&E 69节点算例上验证了所提规划模型的有效性。结果表明，面向配电网可靠性与经济性的SOP规划方法能够有效降低配电网综合成本，实现投资效益的最大化。

Abstract

Soft open points (SOPs)

which have powerful capability of power flow control

can make positive contribution under normal operation and fault conditions of distribution network. The benefits both from the improvement of power supply reliability and operation economy should be taken into account at the planning stage. Planning model of SOPs is proposed in this paper considering the effect of connecting SOP on supply reliability and operation economy in distribution network. The fast-search and the method of finding density peaks clustering are used to aggregate the annual load data

and the typical operation scenarios in distribution network are generated to calculate the improvement cost of operation economy. The calculation method of branch failure rate based on related constraints is adopted

considering the influences of load rate of line current

node voltage and length of line on branch failure rate

the dynamic prediction failure set is generated to calculate the benefits of power supply reliability. A hybrid optimization algorithm

which combines the simulated annealing method with the second-order cone programming

is used to solve the planning model mentioned above. Finally

the effectiveness of the proposed planning model is verified by the modified PG&E 69-node test system. The results show that the SOP planning method facing reliability and economy in distribution network can effectively reduce the comprehensive cost of distribution network and maximize the investment benefits.
