In recent years, the Web service composition technology has developed rapidly, as a result, the energy consumption problem is also increasingly prominent. Faced with this situation, the paper firstly gives out the power model of single service; then derives the model of service composition according to its characteristics, and gives out the corresponding QoS constraints at the same time. After finishing the model, the paper talks about the allocation of feasible path, which is one of the problem in model calculation. The author introduces a graph-plan based searching algorithm, and uses the concept of hierarchical search to solve the problem. At last, the experimental results show that compared with traditional methods, the approach in this paper can not only satisfy the user requests with QoS restricted, but also reduce the energy consumption of service composition effectively.
