Protocols

The open smart grid platform supported protocols can be found in this section. Feel free to add your own protocol or improve an existing protocol adapter.

Protocol Adapters

Protocol Adapter components translate a message from domain adapter components into a protocol message for a smart device. Protocol Adapter components send the protocol message to a smart device using a network connection. The response from the smart device is translated into a domain response message which will be sent to the Core components (which will route it to the domain adapter which issued the request).

OSLP

For the OSLP implementation, 2 components are used. The first component is the protocol adapter for the protocol. It can translate message into the protocol message for SSLD's. Second there's the signing-server component. It is responsible for signing the protocol message using the private key of the platform. The components communicate using a queue-pair. The singing-server can handle multiple protocol adapter instances by utilizing a reply-to queue per protocol adapter instance. Since the protocol adapter component needs to be reachable from a network, it is a requirement that the private key may not be used by the protocol adapter directly. The singing-server component can be deployed in such a way that no network access is available to this component, as the only coupling needed are the queues / the message broker.

DLMS

The DLMS protocol is used for (mainly) smart metering.

IEC61850

The IEC61850 implementation is used for e.g. distribution automation, microgrids and public lighting.

MQTT

The MQTT implementation is used in distribution automation

Basic layout of a protocol adapter

The following diagram shows the basic structure of a protocol adapter. This however does not mean that all protocol adapters will be structured like this, but instead the diagram shows an example of how such a protocol adapter could be structured.
