▪ Increased Reliability

▪ Reduced Energy Costs

▪ Improved Grid Resilience

▪ Lower Emissions

▪ Enhanced Control

▪ Financed Solutions



Decentralized Energy systems and Microgrids have 3 major value

propositions to be quantified and monetized

$ Local generation

Island able

Storage integration

Controllable loads

Economic & Energy efficiency▪ Capex vs Opex

▪ Distributed generator control

▪ Load / storage control

Sustainability▪ Generation / load forecast

▪ Dynamic grid constraint consideration using

state estimator function

Reliability, resilience▪ Black start

▪ Network synchronization

▪ Online Control via HMI / Grid Monitoring and

Control

▪ Enhanced SCADA functionality



Solution for grid/load problems

E.g. Loading of E-cars in semipublic areas/park houses

Local generation

Storage integration

(Controllable loads)

Load Profile with EVs

Peak shaving function with an Electrical Storage System



Microgrid Application for E-Mobility

E-Car OC

AC

DC

Monitoring and control of

decentral power generation

via communication interface

Management of battery

storage via communication

to BMS

Monitoring of available

power and power quality

from the grid

Monitoring and control of

power consumption (e.g.

load shedding)

Monitoring and collection of

charge data of EV-Charging

stations

DC and AC Charging Stations can be controlled

by via communication interface (if available) or

via circuit breaker (emergency)

Control of EV-Charging

stations via OCPP

Checking of availability

reservation of charging

stations and charge status

via App
