A key objective in the design of new aircraft systems is the continuous improvement of overall aircraft efficiency. To achieve this, multiple perspectives, e.g., inside the aircraft galley, are considered, such as process efficiency, weight efficiency, energy efficiency, operational efficiency, etc. Traditionally, aircraft manufacturers apply a top-down approach of electrical system design, where fixed power budgets are allocated to subsystems based on "worst-case" peak loads in specific flight phases. This this sum of nominal loads can lead to overfitted electrical distribution networks. Therefore, this paper presents a bottom-up design and the implementation of a thermal and electrical energy management system for galley operations. An advanced galley energy management approach based on thermal and electrical energy consumption and a decentralized active control within the galley is used. The proposed intelligent control strategy dynamically adjusts heating, cooling and galley inserts operation to maintain optimal power consumption for thermal systems and increase electrical energy efficiency without negative impact on service quality. Results demonstrate significant reduction of the peak in electrical energy consumption and make reductions of weight from electrical power supply system possible due to lower requirements of the maximum amplitude of power and current. This approach offers a potential solution to increasing efficiency in the galley, adapting the workflow of cabin crew, and contributing to future design of aircraft galleys.
