Energy Storage

System controller

(ESS)

Battery Management

System (BMS)

• Planning of optimal use of ESS and other generation assets through

reduction of energy costs or/and increase of revenues according to

storage internal data (technical cost criteria, state of charge), states of

other connected assets, and external drivers (grid tariffs, demand

management requests)

Energy Management

System

Enabling SW components for complex applications:

• Renewable integration subject to

ramp up/down, call-power

constraints (e.g. regulations in

French islands)

• Balancing group optimization/

forecast accuracy increase

• Micro-grid with conventional and

renewable generation resources

and storage devices

• Demand Charge Reduction

Monthly Bill = Energy Cost +

Demand Charges

Optimized power commands to be implemented by ESS and other

energy resources based on forecasts and measurements

Objective: “grid friendly” operation of the micro grid

Minimize grid energy purchase (maximize self-consumption)

Minimize grid power purchase spikes

Minimize grid power feed-in spikes

Bosch Solution: Model Predictive Control (MPC)

Use forecasts for PV(and other RES), Load and in future CHP

Stochastic optimization to control Storage and CHP

Self learning algorithms improve forecasts over time
