Energy management; consecutive steps :

• Battery SOC 60% to 90% => Normal “Operation modes”: Low priority users or limited in time or refused by the system.

/ “ ll ”

Overproduction

• Battery SOC = +/‐ 90% =>“Full power mode”: No time constraints on individual users.

• Battery SOC (State of Charge) => +/‐ 100% + “Full power mode”: “useful dump loads” (snowmelter, heating etc.)

• Further increase in energy => frequency shift (going higher) to slow down electric production.
