PowerSystems.jl¶

PowerSystems.jl supports parsers for a few standard power system data formats:¶

MATPOWER
PSS(R)E v33 .raw and .dyr format
Tabular data (CSV)

`TimeSeriesData`¶

Any Device or Service can contain TimeSeriesData
TimeSeriesData data can describe any field in the Component, or can be arbitrary values
TimeSeriesData can represent forecast data or values with a unique set of timestamps

PowerSimulations.jl¶

PowerSimulations.jl supports a variety of optimization problems:¶

Unit Commitment (UC)
Economic Dispatch (ED)
Optimal Power Flow (ACOPF, DCOPF)
Area Control Error (ACE) & Automatic Generation Control (AGC)

A `Simulation` can be defined to enable a sequence of `DecisionModel`s with control over:¶

Problem specification
- Formulation
- Size
Problem sequencing
Information flow between problems
- Initial conditions
- Parameters

Define the template for the day-ahead and real-time problems¶

In [86]:

template_uc = template_unit_commitment()

Define the Models¶

In this case, we want to define two models with the templates and the Systems that we've already created.

Each model defines a JuMP model
The JuMP model gets updated to represent different time periods

In [88]:

models = SimulationModels(
    decision_models = [
        DecisionModel(template_uc, sys, optimizer = solver, name = "UC", optimizer_solve_log_print = true),
        DecisionModel(template_ed, sys_RT, optimizer = solver, name = "ED", optimizer_solve_log_print = true),
    ],
)

Out[88]:

Decision Models
Model Name	Model Type	Status	Output Directory
UC	GenericOpProblem	EMPTY	nothing
ED	GenericOpProblem	EMPTY	nothing

No Emulator Model Specified

`SimulationSequence` provides a template of how to execute a sequential set of operations problems¶

FeedForward: defines what information is passed
Chronologies: define where information is flowing

In [89]:

feedforward = Dict(
    "ED" => [
        SemiContinuousFeedforward(
            component_type = ThermalStandard,
            source = OnVariable,
            affected_values = [ActivePowerVariable],
        ),
    ],
)

Out[89]:

Dict{String, Vector{SemiContinuousFeedforward}} with 1 entry:
  "ED" => [SemiContinuousFeedforward(VariableKey{OnVariable, ThermalStandard}(""), PowerSimulations.VariableKey[VariableKey{ActivePowerVariable, ThermalStandard}("")])]

In [90]:

DA_RT_sequence = SimulationSequence(
    models = models,
    ini_cond_chronology = InterProblemChronology(),
    feedforwards = feedforward,
)

Out[90]:

Build a `Simulation` using the defined `SimulationSequence`¶

In [91]:

sim = Simulation(
    name = "rts-test",
    steps = 2,
    models = models,
    sequence = DA_RT_sequence,
    simulation_folder = mktempdir(".", cleanup = true),
)

Takeaways:¶

Produciton Cost Modeling has a variety of usages and requires a flexible framework to enable more than a single application
SIIP enables flexible definition of simulation sequencing (the hard part) and problem specifications
The Julia ecosystem allows us to build powerful and extensible modeling and analysis tools
Ultimately, SIIP has proven scalable and fast enough for applied studies, flexible enough to suport technology exploration, and extensible enough to support algorithmic development

PowerSystems.jl

PowerSimulations.jl

PowerSimulationsDynamics.jl

PowerGraphics.jl

SIIPExamples.jl

What's Next?¶

Performance improvements
Features: hybrid plants, demand response agents, outages, contingency analysis, etc.
Integrated workflows: PCM -> ACOPF -> CA -> Stability
Experiments (using PowerSimulations to execute scientifically rigerous analysis... and make it reproducable)
