Flexible power distribution system interconnection switch optimization method and system

The invention discloses a flexible power distribution system interconnection switch optimization method and system, and relates to the technical field of power system planning, and the method comprises the following steps: setting a multiplexer, and building a reconfigurable E-FDSIS model according to a multiplexer state matrix; introducing a random variable model to describe the uncertainty of illumination intensity and the uncertainty of load; and constructing a constant volume model of the reconfigurable E-FDSIS model, and solving the constant volume model to obtain an optimization method. Through calculation, it can be known that the target function result of the method is the minimum, so that the representative power flow balance degree is the best, compared with an existing scheme, the effect of improving the equipment effect can be achieved, and compared with a traditional scheme, the method has the same return on investment expected value. 本发明公开了一种柔性配电系统互联开关优化方法及系统，涉及电力系统规划技术领域，包括以下步骤：设置多路器，根据多路器状态矩阵，
