This paper proposes a heuristic algorithm for transmission line expansion planning based on mixed-integer linear programming(MILP),aiming at addressing nonlinear and nonconvex problems in the planning of transmission lines con-taining pumped storage plants.First the exact solution of the MILP transmission expansion planning(TEP)model is com-bined with the random solution of the metaheuristic algorithm.Second a MILP-based heuristic algorithm(MBH)is intro-duced to solve the problems encountered in linear approximation and metaheuristic processes.Finally the effectiveness of the proposed algorithm is validated on both single-stage TEP using the IEEE RTS-24 node test system.
