METHOD FOR EVALUATING SUPPLY RELIABILITY OF DISTRIBUTION SYSTEM

PROBLEM TO BE SOLVED: To provide a method for evaluating supply reliability useful to understand the feature of a system and to discuss a corresponding remedy by enabling the quantitative evaluation of the supply reliability by considering various types of indeterminant factors which exist in the distribution system. SOLUTION: The method for evaluating the supply reliability of the distribution system includes a step of forming a scenario by considering indeterminacy based on various assuming accidents and a load state (step S1). Then, the method includes a step of executing load accommodation, and a step of examining whether the load accommodation is possible or not for each scenario (S2). The method also includes a step of obtaining a plurality of supply reliability indexes for the respective scenarios from the load accommodation result (S3), and a step of conducting the above processes for all the scenarios (S4). Thereafter, the method includes a step of obtaining an evaluation value (average evaluation value, worst evaluation value) of the supply reliability index of each distribution line utility rate, and a step of obtaining a total evaluation value by normalizing, etc (S5).
