As the power control medium of the network

intelligent multi-terminal flexible distribution switch（FDS）plays a huge application in achieving active and reactive power coordination and optimizing operation condition. In this paper

the expansion of multi-terminal FDS is considered

the constraint limits and position vectors of FDS access is defined and the economic cost optimization configuration model of ADN with FDS is proposed. The planning goal pursues the minimum economic cost of the operating cycle

and comprehensively considers such cost factors as equipment operation

connection loss

network interaction and capacity configuration to configure the FDS access location and port capacity. Furthermore

a hybrid algorithm based on improved genetic algorithm and second-order cone programming is used for the solution.Finally the test is carried out in the feeder group system relying on the actual smart distribution network demonstration project. It is shown by the result that the proposed method can guarantee the reasonable control of comprehensive economic cost

explores the function of active and reactive power coordinated control when using FDS and reactive power compensation and the algorithm is stable and efficient.
