Abstract: The current optimal goal for units start-up during power system restoration is usually a single pursuit, which ignores the safe and stable operation of the system, the importance and distribution of the units. That’s still not enough to ensure a reliable and effective power system restoration in the actual situation. Through establishing the objective function of combination of voltage safety index, importance of unit and unit generating capacity, the optimization problem can be abstracted as a multi-objective combinatorial optimization knapsack problem. After the unit preliminary election by constraint condition, it can solve out the optimization model Pareto optimal solution set by the bat algorithm. Through the example simulation in many aspects compared with other algorithms, it can illustrate the rationality and validity of bat algorithm on solving the multi-objective decision problem.
