Simultaneous siting and sizing of Soft Open Points and the allocation of tie switches in active distribution network considering network reconfiguration

Soft Open Points (SOPs) are power electronic devices and emerging flexible interconnections. The active reactive flow controllability of SOP facilitates to improve the performance characteristics networks. To evaluate contribution SOPs operational improvement, instead a fixed number an optimized configuration is necessary. In addition optimal siting sizing in distribution networks, considering smart switching capability compared conventional through tie switches important. This issue affects decision simultaneous investment for these types equipment. Existing studies have not considered coordinated presence candidate planning scheme allocating them simultaneously. Here, stochastic scenario-based model proposed determine sites sizes allocation simultaneously while obtaining operation strategy during network reconfiguration process. formulated using second-order cone programming approach. optimization problem solved renewable production scenarios different loading conditions. Finally, conducted on IEEE 33-bus 69-bus systems, results presented.
