Information technology - Home Electronic System (HES) application model - Part 3: Model of an energy management system for HES

ISO/IEC 15067-3:2024 focuses on a model of a system in homes and buildings that can manage energy consumption and generation of electricity by devices on premises dynamically in response to electricity availability from:

– sources within the home or building such as solar panels, wind turbines, or storage (stationary or mobile),

– neighbourhood microgrids,

– transactive energy,

– energy aggregators, and

– public utilities.

This document specifies a model including a framework and methods for energy management consisting of interconnected elements that can be configured to support various methods for a Home Electronic System (HES) energy management system. The methods specified are intended to be generic and representative of a wide range of situations. This document applies to the customer grid-edge portion of the electricity grid (within a home or building) and applies even if the consumer has sufficient local power generation to operate without connecting to a public utility.

This document includes an energy management model that balances power supplied from internal and external sources with demand from appliances and electric vehicle chargers. The model offers flexibilit
