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.
