MaykThewessen · 2026-04-06T14:01:34Z

Summary

Implements the project roadmap items: dashboard-style analysis, component data browser, interactive map, saved views, network sharing, and run creation form.

Features

Custom analysis pipelines — 9 analysis types (dispatch area, line loading, price curves, cross-border flows, capacity mix, nodal balance, line flow snapshots) with Plotly, carrier colors, and Polars-accelerated aggregation
Component data browser — Sidebar listing all PyPSA component types, paginated data table with sorting, search, dtype-aware formatting, time-series metadata badges, and inline editing with batch save
Interactive network map — Leaflet + CartoDB Positron basemap with carrier/country-colored buses, capacity-scaled radius, cross-border highlighting, rich popups (generators, loads, storage per bus), collapsible legend with color mode toggle, and hover effects
Saved dashboard views — CRUD API + UI to save/load/delete current filter & tab configuration as named views (public or private)
Network sharing — Share networks with specific users beyond public/private visibility via network_shares join table, with user search and share management dialog
Run creation dialog — Self-service workflow submission with form validation, backend selection, git branch/tag, config file, snakemake args, and import networks

Backend changes

Area	Files
API routes	`components.py`, `map.py`, `views.py`, `analysis.py` (new); `networks.py`, `main.py` (modified)
Schemas	`components.py`, `views.py`, `analysis.py` (new); `network.py` (modified)
Services	`analysis.py` (new); `network.py` (modified)
Models	`SavedView`, `network_shares` table added
Migrations	`0003_add_saved_views.py`, `0004_add_network_shares.py`
Permissions	`can_access()` extended to check network shares
Utils	`carrier_colors.py`, enhanced `serializers.py`

Frontend changes

Component	Purpose
`ComponentBrowser.svelte`	Paginated component data table with sort/search/inline edit
`NetworkMap.svelte`	Leaflet map with carrier/country coloring, legend, rich popups
`SaveViewDialog.svelte`	Save current dashboard config as named view
`ViewSelector.svelte`	Load/delete saved views dropdown
`ShareDialog.svelte`	Share network with specific users
`CreateRunDialog.svelte`	Self-service workflow submission form

Bug fixes included

n.export() → n.export_to_netcdf() (correct PyPSA API)
ReDoS prevention in component search (regex=False)
Cache corruption fix (uncached load for writes, targeted eviction)
Non-admin user search for sharing (dedicated endpoint vs admin-only)
Path validation on network export
Frontend: double-fetch, stale search input, unmount cleanup, network switch state reset

Test plan

🤖 Generated with Claude Code

Port Script_MEE-style dashboard analyses to pypsa-app as a new analysis service layer alongside the existing PyPSA built-in statistics. Adds 7 analysis types (dispatch_area, line_loading_histogram/timeseries, price_duration_curve/timeseries, cross_border_flows, capacity_mix) with canonical carrier colors, dispatch ordering, and country color theming. Performance: orjson for faster JSON serialization in cache and serializer, 128KB file hash chunks, NaN/Inf sanitization in DataFrame serialization, optional Polars for vectorized aggregations on large networks.

Fix critical bugs in analysis service: - Replace unsafe n.buses.get("country", "") pattern that crashes on networks without a "country" column (ValueError on pandas >= 2.0) - Extract _get_bus_countries/_buses_in_country/_bus_country helpers for safe, consistent country lookups across all analysis functions - Add AC line cross-border flow detection (previously only HVDC links) - Handle NaN country values gracefully - Add .fillna(0) to capacity_mix reindex to prevent NaN bars - Refactor cross_border_flows to reduce cyclomatic complexity (PLR0912) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…yPSA#6) Add two new analysis types addressing GitHub issue PyPSA#6: - nodal_balance: per-bus generation vs load at a given snapshot, showing net injection as overlay bar chart (top-N by absolute injection) - line_flow_snapshot: per-line loading % and flow direction at a given snapshot, with color-coded congestion thresholds Both support snapshot_idx parameter for time-step navigation, enabling the frontend to build a "grid playback" tool.

Add full-stack component browser for viewing PyPSA network component data (buses, generators, lines, etc.) with pagination, sorting, search, and time-series metadata. Backend includes PATCH endpoint for editing component data with safe cache invalidation and path validation. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Edit mode with pencil toggle, batch save with yellow highlights for modified cells, confirm-on-discard for unsaved changes, and pagination/ sort disabled during editing to prevent data loss. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Users can save the current dashboard configuration (active tab, carrier/ country filters, individual plot mode) as named views, load them later, and share public views. Includes SavedView model, Alembic migration, CRUD API endpoints, and Save/Load UI in the network detail header. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Lightweight map visualization using Leaflet + OpenStreetMap tiles. Shows buses as circle markers and lines/links as colored polylines with capacity-based width. Popups show component details. Map auto-fits to network bounds and responds to carrier filter selection. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

for more information, see https://pre-commit.ci

Networks can now be shared with specific users beyond public/private visibility. Adds network_shares join table, extends can_access() to check shares, adds share/unshare API endpoints, and includes a Share dialog in the network detail header with user search. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Form with workflow URL, branch/tag, config file, backend selection, and advanced options (snakemake args, import networks, visibility). Validates inputs, submits to API, and navigates to run detail on success. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Fix n.export() -> n.export_to_netcdf() (PyPSA has no .export()) - Add GET /networks/users/search endpoint for non-admin user search - Fix ShareDialog to use new endpoint instead of admin-only listUsers - Remove deadlock risk by dropping explicit cache lock acquisition Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Buses colored by carrier or country (toggle in legend panel) - Bus radius scaled by generation capacity at that node - Per-bus popup shows generator count/capacity, carrier types, load count - Branches: cross-border lines highlighted amber, log-scale width - Hover effects on buses and branches - Collapsible legend with carrier/country color swatches and branch type key - CartoDB Positron basemap for cleaner data visualization - Click-to-filter callback support (onBusClick prop) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
