A procedure for operating an electrical energy system in a building includes a step for collecting a variety of consumption data on the electrical active energy drawn. This active energy is drawn from the public electricity grid and / or from existing energy generators within the building's energy system via a grid connection point. A load profile is determined based on the consumption data. This load profile describes the expected or historical trend of the active energy drawn over a given period. A backup generator for generating and / or supplying electrical energy is then selected based on the load profile. The backup generator is intended to operate instead of, or in addition to, existing energy generators within the building's energy system and / or to reduce the amount of active energy drawn from the public grid.

This invention relates to the field of automatic management technology for ship power plants, specifically to an automatic management system and method for ship power plants based on load prediction. The system includes a load prediction module that receives multi-source data acquired by a data acquisition and fusion module and outputs a predicted load curve for the ship using a pre-trained load prediction model. An optimization decision module dynamically calculates the ship's safety margin based on the predicted load curve obtained by the load prediction module and dynamically generates start-up, shutdown, paralleling, and disconnection control commands for the ship's generator sets. By predicting the future load curve of the ship, this invention can start standby generator sets in advance before the predicted overload risk point, ensuring that paralleling and load transfer are completed before the peak load arrives. This effectively avoids the risk of overload tripping due to generator start-up delays and greatly enhances the robustness of the ship power plant.
