Live Demonstration

DEMO 1: Technical integration of Renewable Energy Resources

(e.g. PV)

• Challenge: renewable generation typically presents a high

variability depending on the weather conditions

• Solution: use energy storage system to smooth RES generation

– using power ramp-rate control:

• Definition of a max ramp-rate (e.g. 10% of the installed capacity

per min)

• Compute setpoints to the Energy Storage System in order to

guarantee max ramp-rate is not surpassed

IMAGEM 2

Live Demonstration

DEMO 2: Peak shaving enabling to flatten load profiles

• Challenge: the ever-growing DER integration (such as EVs) is increasing the volatility

of the load profiles and the peak consumptions

• Need to invest in the reinforcement of the electrical infrastructures, namely at the

secondary substation level

• Solution: use energy storage system to perform energy shifting from peak to valleyperiods

IMAGEM 2

Live Demonstration

DEMO 3: Grid following islanded operation – the frequency control is assured by the

main grid, but the microgrid is kept in a near to zero power flow at the secondarysubstation

• Challenge: ensure a smoother transition between grid-connected and islanded

modes, applicable when the transition is programmed.

• Solution: use energy storage system to ensure power flow control at the point of

common coupling (PCC)

Live Demonstration

DEMO 4: Islanded Operation of the Micro-grid

• Challenge: need to decouple the micro-grid from the main power system:

• due to technical constraints (e.g. disturbance in the upstream network)

• resulting from a decision of the management system (e.g. programmed maintenance)

• Solution: ensure frequency and voltage control at the level of the microgrid. Use

energy storage system to compensate voltage and frequency excursions derivedfrom other microgrid resources.

Live Demonstration

DEMO 5: Black Start

• Challenge: need to restore the energy service after a partial or complete shutdown

of the system.

• Solution: coordinate the micro-grid assets in order to carry out a phased reposition of

the service and bring back normal operation. The energy storage system is used in

first instance to start service restoration, ensuring frequency and voltage control at

the level of the microgrid.

DEMO 6: Economic Operation of the Micro-grid

• Challenge: technical-economic operation of the micro-grid driven by energy

procurement optimization based on energy market tariffs. Reduce energy

acquisition costs at the micro-grid level and increase self-consumption.

• Solution: compute an optimal operation plan, up to 24h ahead, for the micro-grid

assets based on forecasted conditions, such as generation and consumption.

• Use energy storage system as main source of flexibility to the micro-grid.
