Example OPC UA server for local Energy Management Systems (EMS)

Description

This code can be used to create any OPC UA Server, that emulates a local Energy Management System according to the MEMAP data model (https://memap-project.de). Therefore the file createBuildings_MemapDatamodel.py contains the following general methods

• create_Server_Basics
• create_Namespace

as well as the follwoing methods according to the device classes defined in the data model:

• add_General (EMS)
• add_Demand (DEMND)
• add_Producer (CPROD)
• add_VolatileProducer (VPROD)
• add_Coupler (COUPL)
• add_Storage (STRGE)

These functions will add the according devices with all necessary input parameters to the namespace of the OPC UA Server of this mocked EMS.

2 building example

By starting 2Houses_MinimalMemapDatamodel.py two example Mock-EMS are parametrized and two OPC UA servers launched at opc.tcp://localhost:4880 and opc.tcp://localhost:4890. The Servers are simulating current demand and generation according to standard load profiles (CSV-files in data folder), which is updated at the respective node (demand/generation forecasts) every 15 seconds.

The code can run on any device like e.g. raspberry pi, to test or browse the OPC UA Servers with any client - or to simulate any building and virtually connected it to a MEMAP instance (click below).
