About SmartGridready – Motivation and Association

SmartGridready is an independent association dedicated to advancing intelligent networking and communication within the power grid. In doing so, we make an important contribution to Switzerland’s energy transition.

SmartGridready is an initiative, which unites manufacturers, grid operators, technology providers, planners, and users. The association’s mission is to promote open, interoperable, and future-proof solutions for smart energy systems, supporting the digital transformation of the energy sector.

Why SmartGridready?

• Goals: Simplify and standardize integration and communication between energy management systems, devices, and the power grid—regardless of manufacturer. Foster innovation and accelerate the adoption of intelligent energy solutions.

• Benefits: Lower integration costs, greater flexibility, improved security of supply, and a sustainable foundation for digital energy services. All stakeholders benefit from standardized interfaces and a growing community.

• Stakeholders: Manufacturers, energy suppliers, grid operators, planners, architects, technology providers, and end users.

Smart Grids and Energy Management

A smart grid is a modern electricity network that optimizes energy flows using digital technologies, automation, and real-time data. It enables bidirectional energy flows, integration of renewable energy, and stable grid operation through automated load management.

Energy management in buildings and districts involves monitoring, controlling, and optimizing energy consumption. Intelligent systems read measurement data and control loads to reduce costs and increase efficiency. Buildings and districts interact with the grid by feeding in surplus energy or flexibly adjusting their consumption. Decentralized systems and microgrids increase resilience and independence.

The benefits: lower costs, reduced CO2 emissions, higher security of supply, and more control for users.

Table 3 Component Description

Component	Description
EMS	Energy management system for buildings, districts, or plants to optimize energy consumption.
Grid Interface	Interface to the distribution grid operator for feed-in and load management and tariff information.
Inverter (PV-Inverter)	Converts the direct current generated by PV systems into alternating current for households and the grid.
Load Management (EVSE)	Infrastructure for the safe charging of electric vehicles, including communication and safety.
Heat Pump	Efficient device for heating and cooling by transferring heat between the indoor and outdoor environment.

SmartGridready Concept

The goal of SmartGridready is to ensure seamless interoperability between energy management devices, energy consuming, energy producing and energy measuring devices, allowing an intelligent power management.

SmartGridready distinguishes between:

• Controlled devices referred to as Product

  Examples for Product devices are smart-meters, heat pumps, EVSE charging stations, PVA inverters.

• Controlling devices referred to as Communicator

  Examples for Communicator devices are Energy Management Systems (EMS) and Flexibility Manager devices operated by distribution system operators.

SmartGridready establishes an abstract common framework to enable interoperability between system components, allowing Communicator devices to communicate with Product devices in a unified manner, independent of the Product suppliers and their proprietary communication interfaces.

Interoperability is achieved by Functional Profile definitions and External Interface Definition (EID) files in XML that build the core of the SmartGridready specification. The External Interface Definition files define a set of Functional Profiles exposed by a specific Product and the rules to adapt the communication from the generic SmartGridready interface to the proprietary Product interface.

Table 4 Component descriptions

Component	Description
Flexibility Manager	Acts as a load manager in a power grid. Allows flexible power management by communicating with Energy Managers EMS within sub-networks, residential areas and buildings.
Communicator	Part of the Flexibility Manager or EMS that communicates with Product devices within the system. SmartGridready allows a communicator communicate with any Product device through standardized interface.
Functional Profile	The Functional Profile defines a set of standardized functionalities exposed by a Product device. The Functional Profile forms the core of the SmartGridready standard, enabling flawless communication with any Product device that conforms to the SmartGridready specification.
Energy Manager	Acts as a power manager within a building. Provides a Smart Grid Connection Point SGCP receiving commands from Flexibility Manager devices.
Heat pump, PVA inverter, EVSE charging station	Samples for Product devices
