Abstract: With the continuous promotion of the construction of smart grid and the in-depth coupling between cyber system and distribution physical system, the degree of distribution automation is bound to be higher and higher, and the planning strategy of intelligent terminal becomes increasingly important in the development of distribution automation. Based on this, a bi-level planning model of distribution network intelligent terminal was established considering the influence of reliability and economy reconfiguration. The upper level is the comprehensive optimization of the comprehensive investment cost and operation cost of the system, so as to carry out the location planning modeling and type-selection planning modeling of the intelligent terminals as well as the optical cable laying planning modeling. Based on the results of the upper level planning, the lower level reliability reconfiguration part is based on the multi-scenario accident outage time decomposition method. Combined with the results of intelligent terminal configuration on the load-power transfer path of all kinds of transferable load, considering the influence of remote control on system reliability caused by whether the circuit breaker supports remote control or not, a quantitative model for reliability evaluation of distribution system was established. The lower level economy reconfiguration part took into account power flow constraints, security constraints, topology constraints and switching action constraints to establish a dynamic mixed integer linear model based on second order cone programming (SOCP) to analyze the economy of the planning results in the normal operation of the system. Finally, this bi-level model was optimized by discrete binary particle swarm optimization algorithm (BPSO), and the effectiveness of the planning method was verified based on an IEEE-33 system and a Bus-152 system.
