Abstract

This paper analyzes the electrical parameters of areas that contain distributed generation facilities. It demonstrates the necessity of stricter requirements to the performance of energy system automated systems, especially in island operation. It is noted that implementing a special procedure for truncating the standard sequential analysis (Wald analysis) for automated decision-making is a time-consuming process. By ensuring the constancy of first- and second-kind errors at each step of the Wald analysis, one can generate adaptable settings. The paper uses evidence from an automated underfrequency load shedding unit to show that a modified sequential analysis algorithm performs twice as fast. The authors present guidelines on how to adopt this modified algorithm in existing or newly developed energy system automated systems.
