Optimization of Energy Management in Office Buildings Equipment with Photovoltaic Generation and Storage Systems during Power Outages Considering BCP Levels

Japan, a country prone to disasters, frequently experiences large-scale power outages caused that disrupts business operations. As a result, resilient office buildings equipped with photovoltaic power generation and storage batteries are gaining attention for their potential to enhance business continuity. To support advance planning of business continuity plans (BCPs), numerous mathematical models have been developed to optimize building operations during power outages. However, accuracy can lead to operational failures during actual disasters, resulting in extensive damage. Therefore, it is essential that these models incorporate economic viability, realistic operational strategies, and disaster-related uncertainties. Despite this need, no existing model integrates all of these factors. This study proposes an operational optimization model for office buildings during power outages that accounts for economic usefulness, realistic operation, and disaster uncertainty. The effectiveness of the proposed model will be evaluated based on its economic benefits and the practicality of its operational plans.
