OpenEMS Energy

Implementations and Services for OpenEMS Energy Schedules.

To understand the functionality and terms used in this implementation, its helpful to refer to the Jenetics manual available at https://jenetics.io/.

Terms

Following terms and relations to Jenetics are used:

Mode

The Mode refers to a predefined operation mode of a OpenEMS Controller. A Mode is represented in Jenetics as a Gene.

Period

The Period refers to a space in time. A Period holds one Mode per OpenEMS Controller to define its operation mode within this period of time. A Period is represented in Jenetics as an index within a Genotype of Chromosome s.

Schedule

A Schedule refers to a set of multiple Periods. A Schedule is represented in Jenetics as a Genotype.

Optimization

A Optimization consists of multiple Schedules that are typically simulated within a 15-minutes period. A Optimization is represented in Jenetics as a Population.

Context and their Scopes

Energy Scheduler uses Context objects that hold information that is relevant to a certain Scope of an Optimization run.

OpenEMS Controllers use delegation to EnergyScheduleHandler objects to handle requirements of the Energy Scheduler.

GlobalOptimizationContext (goc)

The GlobalOptimizationContext - commonly abbreviated as goc - is a Context that is valid throughout an entire Optimization. It’s typically recreated once per 15-minutes.

Example data: - Prediction of Production and Consumption - List of all Energy Schedulers - Global Limits like a limited Grid power - …​

GlobalScheduleContext (gsc)

The GlobalScheduleContext - commonly abbreviated as gsc - is a Context that is valid for simulation of one Schedule. It’s typically recreated multiple times per second.

Example data: - Initial Energy of an ESS at the start of a Period.

ControllerOptimizationContext (coc)

The ControllerOptimizationContext - commonly abbreviated as coc - is a Context that is valid throughout an entire Optimization for one Controller/EnergyScheduleHandler. It’s typically recreated once per 15-minutes.

ControllerScheduleContext (csc)

The ControllerScheduleContext - commonly abbreviated as csc - is a Context that is valid for simulation of one Schedule of one Controller/EnergyScheduleHandler. It’s typically recreated multiple times per second.
