On the basis of considering following factors such as the leveling of peak and load simultaneity of interconnected system, the tie\|line capacity and its availability, the capacity and energy constraint of each system, a new model and corresponding algorithm for evaluating the reliability benefits of interconnected power systems is put forward. In this algorithm the leveling of peak and load simultaneity of interconnected system are accurately simulated by hourly calculation, the tie\|line capacity and its availability can be perceived in the reliability calculation of systems in series, the capacity and energy constraint of each system are determined by random simulation. A practical interconnected system is calculated by presented model and algorithm, the interconnection benefits is analyzed in detail, the correctness and effectiveness of the algorithm are tested and verified.
