Optimal Operation Planning of a Storage Battery System Based on Comprehensive Scenario Analysis Concerning Uncertainty of Solar Radiation Time Series

—Towards Effective Use of Solar Power Generation for Peak Load Reduction—

Abstract

Significant amount of solar power and other renewable energies will be exploited in the future low-carbon society. But the weather-dependent instability of renewable energy production makes it difficult for energy management systems to use those types of energies in accordance with varying demands. This paper proposes a method for managing a hybrid system of solar power and storage batteries, which has been developed to cope with the unpredictable change of solar power production so that the peak consumption of utility power is effectively reduced, and evaluates that method using experimental data obtained through a microgrid system at the Fujitsu Kawasaki Research & Manufacturing Facilities.
