Maximum Power Consumption Excess Forecast Alert for Large-Scale Power Consumers

Abstract

Large-scale power consumers, such as buildings and factories, make high-voltage power contracts with the Japanese electric power companies. The basic fee for high-voltage power contracts is based on the maximum power consumption in the past year. If the power consumption in the present month does not exceed the maximum power consumption in the past year, large-scale power consumers can suppress the basic fee. In this research, we consider the characteristics of each industry's power consumption. As a result, we have improved the accuracy of excess forecasts and contributed to effective alerts to many large-scale power consumers.
