Final answer:
The AC SHED ESS and DC SHED ESS buses are automatically shed by the system when certain conditions are met, such as an overload or fault condition, to maintain stability and protect the power system.
Step-by-step explanation:
The AC SHED ESS and DC SHED ESS buses are automatically shed by the system when certain conditions are met.
For example, in a power system, if there is an overload or fault condition, the system may shed non-essential loads to prevent a complete blackout or damage to critical equipment.
This shedding of AC and DC buses helps maintain stability and protect the integrity of the power system.
