A thermal generator, such as a fossil fuel or nuclear generator, that can start-up again from a hot, warm, or cold state.

ThermalMultiStart has a detailed representation of the start-up process based on the time elapsed since the last shut down, as well as a detailed shut-down process. The model is based on "Tight and Compact MILP Formulation for the Thermal Unit Commitment Problem.". For a simplified representation of the start-up and shut-down processes, see ThermalStandard

Arguments

  • name::String: 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::Bool: Indicator of whether the component is connected and online (true) or disconnected, offline, or down (false). Unavailable components are excluded during simulations
  • status::Bool: Initial commitment condition at the start of a simulation (true = on or false = off)
  • bus::ACBus: Bus that this component is connected to
  • active_power::Float64: Initial active power set point of the unit in MW. 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, validation range: active_power_limits
  • reactive_power::Float64: Initial reactive power set point of the unit (MVAR), validation range: reactive_power_limits
  • rating::Float64: Maximum AC side output power rating of the unit. Stored in per unit of the device and not to be confused with base_power, validation range: (0, nothing)
  • prime_mover_type::PrimeMovers: Prime mover technology according to EIA 923. Options are listed here
  • fuel::ThermalFuels: Prime mover fuel according to EIA 923. Options are listed here
  • active_power_limits::MinMax: Minimum and maximum stable active power levels (MW)
  • reactive_power_limits::Union{Nothing, MinMax}: Minimum and maximum reactive power limits. Set to Nothing if not applicable
  • ramp_limits::Union{Nothing, UpDown}:, validation range: (0, nothing)
  • power_trajectory::Union{Nothing, StartUpShutDown}: Power trajectory the unit will take during the start-up and shut-down ramp process, validation range: (0, nothing)
  • time_limits::Union{Nothing, UpDown}: Minimum up and Minimum down time limits in hours, validation range: (0, nothing)
  • start_time_limits::Union{Nothing, StartUpStages}: Time limits for start-up based on turbine temperature in hours
  • start_types::Int: Number of start-up based on turbine temperature, where 1 = hot, 2 = warm, and 3 = cold, validation range: (1, 3)
  • operation_cost::Union{ThermalGenerationCost, MarketBidCost}: OperationalCost of generation
  • base_power::Float64: Base power of the unit (MVA) for per unitization, validation range: (0.0001, nothing)
  • services::Vector{Service}: (default: Device[]) Services that this device contributes to
  • time_at_status::Float64: (default: INFINITE_TIME) Time (e.g., Hours(6)) the generator has been on or off, as indicated by status
  • must_run::Bool: (default: false) Set to true if the unit is must run
  • dynamic_injector::Union{Nothing, DynamicInjection}: (default: nothing) corresponding dynamic injection device
  • ext::Dict{String, Any}: (default: Dict{String, Any}()) An extra dictionary for users to add metadata that are not used in simulation.
  • internal::InfrastructureSystemsInternal: (Do not modify.) PowerSystems.jl internal reference
