PowerDynamics.jl - v5.0.0

PowerDynamics v5.0.0

Version 5.0.0 Changelog

Two themes: the ecosystem move that comes down from
NetworkDynamics v1.0/v1.1
(ModelingToolkit v11, the reworked initialization pipeline, SciML v3), and a per-unit
overhaul that turns base values from per-device constructor arguments into a property of
the bus and line.

The library saw a broad naming and unit cleanup in the process. Renamed parameters fail
loudly at construction, so the practical upgrade path is to build your models and follow
the errors — check the docstrings for anything that no longer takes the argument you
pass it. The parts that change numbers rather than names are called out explicitly
below.

Breaking: ecosystem

All NetworkDynamics v1.0 breaking changes apply unchanged. PowerDynamics
@reexports NetworkDynamics, so its API is part of the PowerDynamics API — most
notably set_mtk_defaults! → non-mutating set_mtk_defaults, symbolic expressions as a
guess now error in favour of initf/guessf, find_fixpoint takes an NWState, and
MTK models are no longer simplified by mtkcompile. See the
NetworkDynamics release notes
for the details and the rewrites. NetworkDynamics ≥ 1.1.0 is required.
ModelingToolkit → ModelingToolkitBase + SciCompDSL
(#261). MTK v11 split into
ModelingToolkitBase (MIT) and ModelingToolkit (AGPL); PowerDynamics depends only on
the MIT half, and @mtkmodel moved out into SciCompDSL. Along with it: Symbolics ≥7,
SciMLBase ≥3 and the OrdinaryDiffEq* subpackages ≥2.
The Bus(...)/Line(...) deprecations are removed; use compile_bus/compile_line.

Breaking: per-unit system

Base values are now part of the model structure rather than something you pass to each
device. There is a new documentation chapter, "Per-Unit Systems", that explains the
whole scheme; the short version:

Global bases with accessors: a system power base (100 MVA), frequency base (2π·50
rad/s) and fallback voltage base, set through the new exported set_Sbase!,
set_ωbase!/set_fbase! and set_Vbase! (plus get_* counterparts). They are read at
model construction, so set them before building anything.
New SystemBase component carries the global quantities (Sbase, ωbase, ωframe).
Exactly one instance named systembase sits at the top level of every bus and line;
MTKBus/MTKLine/compile_bus/compile_line place it for you.
BusBar and LineEnd carry Vbase, the one genuinely local base, along with derived
Ibase/Zbase/Ybase and SI observables (u_kV, P_MW, Q_MVAr, i_kA). Sbase is a
three-phase power and Vbase line-to-line, hence Ibase = Sbase/(√3·Vbase) — the exported
helper Ibase(S, V) changed accordingly.
Devices inherit their bases and no longer take S_b/V_b/ω_b. Drop those arguments
at the call site: set the power/frequency base globally and the per-bus voltage base with
the new MTKBus(…; Vbase=…) / compile_bus(…; Vbase=…) keyword. Vbase propagates
outward from there — a line end inherits from the bus it connects to (a transformer is
just a line whose two ends resolve differently, ratio included), and a satellite/injector
bus inherits from its hub. An explicitly set value always wins.
Sn/Vn are now optional, weakly defaulting to the bus base, so a machine running on
the system base needs no rating at all.
LineEnd requires a side keyword (:src/:dst) — it selects which bus the end
inherits from. MTKLine passes it automatically; hand-rolled line models must be updated.
New check_base_consistency(s::NWState), run automatically by initialize_from_pf[!]
(check=:error by default, :warn/:none to downgrade), verifying that the global bases
agree everywhere and that every line end and satellite bus matches the bus it hangs off.

Breaking: naming and units in the library

Setpoints are spelled …set (Pset, Qset, Vset, ωset, …); n/nom is reserved
for genuine nameplate ratings (Sn, Vn). Models ported from elsewhere keep their
source's names so they can still be checked against the original — the AVRs' vref and
the governors' ω_ref/p_ref are unchanged.
EMT components name parameters for what they hold: reactance X and susceptance B
instead of L and C, which stored reactance/susceptance values all along. The topology
is in the model name, so there is no ambiguity.

Frequency vocabulary is split three ways. One symbol used to do three unrelated jobs:

symbol	kind	unit	meaning
`ωbase`	unit	rad/s	converts SI time ↔ pu; the frequency at which `X = ωbase·L`, `B = ωbase·C` were evaluated
`ωframe`	gauge	pu	speed of the global dq frame; pinned to `1`
`ωset`	setpoint	pu	frequency a droop/damping law is commanded to hold

Consequences throughout the library: an ω0 = 2π*50 keyword on the dynamic shunts,
branches and ComposableInverter models is gone (they take ωbase from the bus instead),
every place where the reference frame was an invisible literal 1 now writes ωframe,
and the dq cross-coupling terms of the EMT components gained the ωframe factor they were
missing. Since ωframe == 1 these are all algebraically identical to before — the OpenIPSL
comparison tests pass unchanged.

Three models genuinely change behaviour and their parameter sets do not carry over:
- Swing and IdealDroopInverter had no ωbase at all, so with ω in pu the
  angle advanced ~314× too slowly. Both now use Dt(θ) ~ ωbase*(ω - ωframe). Swing's
  M is the inertia M = 2H in seconds (default 6.0, i.e. H = 3 s) and D a damping
  power coefficient in pu/pu (default 2.0); IdealDroopInverter's Kp is a pu droop
  (default 0.05). Retune existing parameter sets against these units. A physically sized
  machine is lightly damped, so call sites that want a quickly settling transient now pass
  a D well above the default.
- DroopOuter/DroopInverter: ω is now pu rather than rad/s, making Kp a
  dimensionless droop (default 0.05). Convert an existing value with
  Kp_new = Kp_old/ωbase — with that substitution the rewrite is an exact identity, and
  the linearization is unchanged.
IdealDroopInverter and DroopInverter now also share the same droop defaults
Kp = Kq = 0.05; they previously disagreed on Kq, so swapping one model for the other
silently changed the voltage stiffness.
Smaller renames in the same spirit — VoltageDependentLoad's Vn → Vset,
PSSE_GENCLS's output port ωout → SPEED_out, and unified state/output names on the
two PLLs. Consult the docstrings.

Initialization

Backward initialization through nested components. NetworkDynamics' new
initf/guessf metadata lets each model carry its own init recipe; composed together
they chain into a DAG that can fix every free variable from the powerflow alone, with no
nonlinear solve at all. The new tutorial "Backward Initialization of Nested Models" builds
a full generator bus that initializes to "No free variables!", and a new "Advanced
Initialization" documentation chapter covers the mechanics.
@pfinitconstraint/@pfinitformula hygiene fixed: both macros mishandled escaping, so
a constraint could not close over local runtime variables. They now capture locals
correctly and show prints the macro form you wrote.
initialize_from_pf no longer ignores pfs0 — the supplied start state was
overwritten with the powerflow network, so a hand-tuned guess had no effect. tol/nwtol
are now forwarded to the residual check.

Library

Optional stator dynamics in SauerPaiMachine via SauerPaiMachine(; stator_dynamics=true).
compile_bus/compile_line accept a bare injector/branch, wrapping it in
MTKBus/MTKLine automatically instead of erroring.
New mtkcompile keyword on compile_bus/compile_line, forwarded to
VertexModel/EdgeModel.
Bug fixes: ClassicalMachine's Park transform applied the current base ratio upside down
(wrong currents whenever Sn ≠ Sbase); a disconnected ComposableInverter kept driving
its LCL filter and wound up to ≈70 pu internally; limited-integrator callbacks now resolve
the integrator state through the observed-alias chain instead of assuming a name survives
compilation (visible in PSSE_HYGOV); TurbineGovTypeI could not be constructed at all
(it is constructible now, but remains untested — there is no reference trajectory for it).
Saturation functions (QUAD_SE, EXP_SE, PSSE_ESST4B's FEX_function) are AD-safe and
use NaNMath, so a slightly out-of-range argument no longer throws a DomainError
mid-initialization.

Documentation

New chapters: "Per-Unit Systems" and "Advanced Initialization" (see above).
New "Getting Started with Julia" section
(#276): the setup page was
rewritten and joined by "Environment Management" and an opinionated "How to Structure
Research Projects" guide, aimed at users who arrive at PowerDynamics before they arrive at
Julia.
New tutorial "Backward Initialization of Nested Models"; the EMT toymodel example was
overhauled, and the initialization and modeling-concepts chapters were reworked for v5.

PowerDynamics v4.0.0

Diff since v3.1.6

Major Breaking Release
In Q2 2024, we began a complete rewrite of PowerDynamics.jl, bringing it much closer in alignment with the modern SciML stack. This rewrite heavily leverages ModelingToolkit.jl for equation-based models and includes a vastly modernized version of our backend, NetworkDynamics.jl.

The 4.0.0 update incorporates all of these changes. We consider the modeling concepts and simulation tools stable enough for release. The library, however, is marked as experimental for now and may change in upcoming minor versions — but you can copy the model definitions into your own code if you rely on an “old” model.

The new version has improved significantly in terms of modeling, initialization, and solution analysis. However, some models and tools previously available are not yet available. If you want to continue using the (unmaintained) old version, stick with PowerDynamics@v3.
