Abstract

See full text

In a method of determining reliability in an electric power system, various data including data representing generated energy and load amount and connecting status of the power system, is inputted, and a series of cyclic processes including a calculation regarding Jacobian are executed for the reliability decision. If variation of the generated energy and load is less than a predetermined value and the connecting status is not varied, the calculation process regarding the Jacobian is not executed but the previous processing result is used, while if the connecting status is varied, the previous processing result is partially corrected.
