Simulation

In order to set up a simulation in openems with

• The electrial load is read from a CSV-file

• PV production is read from a CSV-file

• correctly running controller ess balancing

Implement the following configurations

Configuration	Relevant parameters
controller ess balancing	Component-ID = ctrlBalancing0 Ess-ID = ess0 Grid-Meter-ID = gridmeter
Scheduler All Alphabetically	Component-ID = scheduler0
Simulator Datasource	Component-ID = datasource0 Factor = 1000 Source = H0_HOUSEHOLD_SUMMER_WEEKDAY_STANDARD_LOAD_PROFILE
Simulator Datasource	Component-ID = datasource1 Factor = 1 Source = H0_HOUSEHOLD_SUMMER_WEEKDAY_PV PRODUCTION
Simulator EssSymmetric Reacting	Component-ID = ess0
Simulator GridMeter Reacting	Component-ID = gridmeter0
Simulator NRCMeter Acting	Component-ID = meterCons0 Datasource-ID = datasource0
Simulator PV-Inverter	Component-ID = meter2 Datasource-ID = datasource1

Controller logic (Priorities)

See:

• OpenEMS / architecture / scheduler

• OpenEMS / architecture / cycle

Controller Hierarchy

• The first controller wins.

• All the following controllers cannot overwrite the predecessors.

• Exception: PV-limiters are handled differently: there the last limiter wins.

• The writing only happens in the output phase, i.e., after all controllers have been processed.
