Package: PowerOperationsOpenAPIModels · Source: Operations/StaticInjection/HybridSystem.json

A hybrid system co-locating a thermal unit, electric load, storage, and/or renewable unit behind a single grid interconnection.

Properties

Property	Type	Required	Unit	Description
id	integer	yes	—	Unique integer identifier for this component.
name	string	yes	—	Name of the component. Components of the same type (e.g., PowerLoad) must have unique names, but components of different types (e.g., PowerLoad and ACBus) can have the same name.
available	boolean	yes	—	Indicator of whether the component is connected and online (true) or disconnected, offline, or down (false). Unavailable components are excluded during simulations.
status	string (OperationalStates)	yes	—	Operating state of the unit at the start of a simulation.
bus	integer	yes	—	ID of the bus that this component is connected to.
active_power	number	yes	MW / pu (by power_units)	Initial active power set point of the unit. For power flow, this is the steady state operating point of the system. For production cost modeling, this may or may not be used as the initial starting point for the solver, depending on the solver used. Units: per power_units — NATURAL_UNITS: MW, COMPONENT_BASE: pu .
reactive_power	number	yes	MVAr / pu (by power_units)	Initial reactive power set point of the unit. Units: per power_units — NATURAL_UNITS: MVAr, COMPONENT_BASE: pu .
base_power	number	yes	MVA	Base power of the unit for per unitization, which is commonly the same as interconnection_rating. Units: MVA.
power_units	string (UnitSystem)	yes	—	Unit basis for this component’s power-family fields (active/reactive/apparent power, ratings, limits, ramp rates). COMPONENT_BASE: per unit on this component’s own base_power. NATURAL_UNITS: the field’s physical unit.
operation_cost	MarketBidCost	yes	—	MarketBidCost of operating the hybrid system.
thermal_unit	integer or null	—	—	ID of a thermal generator with supertype ThermalGen, if any.
electric_load	integer or null	—	—	ID of a load with supertype ElectricLoad, if any.
storage	integer or null	—	—	ID of an energy storage system with supertype Storage, if any.
renewable_unit	integer or null	—	—	ID of a renewable generator with supertype RenewableGen, if any.
interconnection_impedance	ComplexNumber	—	pu	Impedance between the hybrid system and the grid interconnection. Per-unit on base_power. Units: pu.
interconnection_rating	number or null	—	MVA / pu (by power_units)	Maximum rating of the hybrid system’s interconnection with the transmission network. Set to null if not applicable. Units: per power_units — NATURAL_UNITS: MVA, COMPONENT_BASE: pu .
input_active_power_limits	MinMax	—	MW / pu (by power_units)	Minimum and maximum stable input active power levels. Set to null if not applicable. Units: per power_units — NATURAL_UNITS: MW, COMPONENT_BASE: pu .
output_active_power_limits	MinMax	—	MW / pu (by power_units)	Minimum and maximum stable output active power levels. Set to null if not applicable. Units: per power_units — NATURAL_UNITS: MW, COMPONENT_BASE: pu .
reactive_power_limits	MinMax	—	MVAr / pu (by power_units)	Minimum and maximum reactive power limits. Set to null if not applicable. Units: per power_units — NATURAL_UNITS: MVAr, COMPONENT_BASE: pu .
interconnection_efficiency	InOut	—	—	Efficiency [0, 1.0] at the grid interconnection to model losses in and out of the common DC-side conversion. Set to null if not applicable.
dynamic_injector	integer or null	—	—	ID of the corresponding dynamic injection device, if any.
