Stand-alone system for optimal control and management of energy flows in positive-energy buildings

Abstract

The invention concerns an autonomous, connected and mobile system for managing and controlling active and reactive energy flows from energy sources, the storage system and loads in a building. This system enables users to reduce their energy bills, their carbon footprint and improve their comfort, while offering services to the main network such as reducing energy losses, consumption peaks responsible for additional costs, harmonics and phase imbalance, while improving the power factor. The innovation offers a complete, mobile and ready-to-use solution, integrating communication, energy conversion, supervision and diagnostic interfaces. The system optimizes the distribution of active and reactive power from different distributed energy sources, such as photovoltaic and / or wind panels and energy storage systems. The system also provides intelligent management of the building's electrical loads (heating, appliances, etc.), adjusting their operation according to energy needs, weather conditions, occupant preferences and electricity tariffs. The energy management system integrates connected acquisition, optimization and intelligent control systems featuring advanced artificial intelligence algorithms, capable of measuring, estimating and predicting key parameters such as active and reactive power consumption, weather conditions and energy production. This data is used to optimize energy consumption and production over the long term (30 days) and in real time, reducing the impact of forecast uncertainties on energy management efficiency.
