Applications for statistical theory and remote metering infrastructure in research load profile building

Abstract

In a power system, the load has the same operating rules constitutinge a kind of load is called the load components., Eeach component loads can be divided into many different groups loads. The objective of the load research is to build an electricity load profile of load components and, load groups. Based on the probability and statistics theory, the authors studiyes direct estimation method, ratio estimation method and stratification estimator to build the load profile of load components, load group in the power system of Da Nang Power Company based on load samples. Also, the authors build program to give the results by the Microsoft Access connect remote metering infrastructure and customer management information system (CMIS).
Key words: load research; ratio estimator; direct estimator; stratification estimator; load profile; statistics.
