A Study on Design of Electricity Procurement Plan

Abstract

In 2016, the retail of electricity sales has been completely liberalized in Japan. It has been getting more important for retailers to predict the energy consumption of customers. However, it is very complex to predict the energy consumption accurately because there are uncertainties and many factors to be considered. This paper proposes a methodology to design of electricity procurement plan considering uncertainties of energy consumption. Using K-Means clustering methodology, we found that there are some patterns in electricity consumption. In this methodology, electricity consumptions are classified into these patterns with temperature data. In a case study, we evaluate the usefulness of the methodology for design of procurement plan.
