Abstract：Firstly, this paper establishes the grid’s security hierarchy standard considering transmission margin. With the constraint of network loss, a multi-objective model is built which consists of the power generation cost and the balance degree of the power grid. Secondly, nodal net injection uncertainty is simulated by random numbers obeying normal distribution. Then the improved multi-objective bacterial colony chemotaxis (MOBCC) optimization algorithm is used to obtain the Pareto optimal solutions. The optimal solutions form the optimal economic operation curves with zero difference curres. Then according to the sate level demand for security and economy of power grid, the farther point pair to define the initiate enclosing disk of incremental algorithm (FIIA) is adopcled to obtain the optimal security economic region. The evaluation indexes of security and economy are defined to refect the security and economy positions in the whole intervals. Finally the results show that both security and economy can be obtained by the proposed method. The improvement of economy under the premise of network security is of practical significance to realize the safe and economic operation of power grid.
