The Load Management Control block is responsible for regulating the flow of the load (active power) through the Point of Common Coupling (PCC), when the microgrid is connected to an external AC-grid, by allowing the user to adjust the active power settings.

Mask and Parameters

The Load Management Controller block contains the following configuration mask:

Name	Unit	Description
Sampling time	s	Time step for the simulation
Diesel minimum power	pu	Minimum values for Diesel generation
Diesel maximum power	pu	Maximum values for Diesel generation
BESS maximum power	pu	Maximum values available for BESS
Load shedding maximum reduction	pu	Maximum values of Load shedding reduction

Inputs, Outputs and Signals Available for Monitoring

Inputs

Name	Unit	Description
RER_Pref_in	pu	Combined reference powers for all Renewable Energy Resources (RERs) (WT+PV)
Load_Tot_Pref_in	pu	Combined reference powers for all loads (DR, Sheddable, Critical and PHIL)
Lshed_Pref_in	pu	User-defined power reference for sheddable load
Load_red_Pref_in	pu	Excess load within the Microgrid (greater than 0 means load must be reduced)
LDR_Pref_in	pu	User-defined power reference for Demand Response (DR) load
islanded	-	Specifies whether the Microgrid is islanded/Grid connected (0 = Grid connected, 1 = islanded)
disp_mode	-	Internal mode of the real-power (dispatch) controller

Outputs

Name	Unit	Description
Tot_L_Reduction	pu	Total amount of load reduction used to adjust the BESS's power reference.
LDR_Pref	pu	Power reference sent to the demand response load
LDR_reduced	-	Status of the demand response load (0= load is not reduced, 1 = load is reduced)
Lshed_Pref	pu	Power reference sent to the sheddable load
Load_shedded	-	Status of the sheddable load (0 = load is not shedded, 1= load is shedded)
