Abstract A multiobjective optimal service restoration model for integrated ship power system is proposed. The evaluating indicators of service restoration are normalized based on linear pattern membership functions, and integrated into a single objective function by using a weighted product functional operator. An analytic hierarchy process is adopted to solve the weight of each index which is more convenient to be apprehended and operated by decision-maker. To test the multiobjective optimal model, it is applied to an improved simulated annealing genetic algorithm based on two-dimension encoding method for service restoration of integrated power system. The test results on a typical integrated power system show that the model can balance each objective to avoid extreme results, and achieve the restoration power regulation of large loads, which make restoration schemes more practical.
