The subject of the contract includes the application of an innovative EMS energy management system. This system aims to manage electrical energy from the PV installations. It will be based on a self-learning algorithm that recognizes situations in which energy is fed into the grid from the PV installation and reacts to overproduction by enabling additional loads in the facility. The system will have the capability to: measure energy consumed and fed into the power grid, connect loads in the facility that, in the case of overproduction, can be activated to consume electricity in the facility, block the outflow of energy to the power grid. Self-learning algorithms, also known as machine learning algorithms, will significantly support the operation of photovoltaic installations in private homes in several key areas: - Energy Production Forecasting: The algorithm can analyze historical weather data and current forecasts to more accurately predict the amount of energy that photovoltaic panels will be able to generate on a given day or week. - Monitoring and Fault Detection: The algorithm can monitor the performance of each panel and detect anomalies, such as power drops, that may indicate the need for maintenance or repair. - Energy Storage Optimization: For homes with energy storage, the self-learning algorithm predicts when it is best to charge and discharge batteries based on projected energy demand and solar energy production. - Energy Consumption Optimization: By collaborating with a smart home management system, the algorithm can learn residents' energy consumption patterns and propose solutions to minimize energy consumption at times when production is low.
