The mathematical model of switch optimization and the solution method based on immune algorithm are given. The calculation methods of switch investment, operation and maintenance cost and power loss are analyzed, and the switch optimal allocation model is established based on the annual value method. The model is a constrained, non-differentiable, non-continuous combinatorial optimization model. The algorithm of solving the model is given based on immune algorithm. Through the model calculation to determine the optimal configuration of the switch the number and location, and get the system reliability, investment costs and power loss and so on. The calculation example shows that the proposed model and algorithm have strong engineering practicability, immune algorithm has better global convergence and faster convergence speed
