Bobby NoelteandGitHub ba76087db9 feat: electricity fee provider framework and generic providers (#1235)
Add new provider class for electricity fees providers.

Add the generic providers:
- ElecFeeFixed
- ElecFeeImport

The providers provide predictions for:

- elecfee_consumption_amt_wh:
  Total fixed fee for consumed energy per Wh [amount/Wh]. This is the accumulation of all
  fixed per-Wh fees payable on "consumed energy - such as network charge, concession fee,
  and electricity charge - into a single amount.
- elecfee_consumption_percent_amt:
  Total fixed surcharge on consumed energy, given as a percentage of the monetary amount
  already charged for that energy [%]. This is the accumulation of all percentage-based
  surcharges payable on top of the consumed-energy fee - such as VAT - into a single
  percentage. This is a percentage of the fee amount, not a per-Wh rate.
- elecfee_feedin_amt_wh:
  Total fixed deduction from feed-in energy per Wh [amount/Wh]. This is the accumulation of
  all fixed per-Wh charges deducted from feed-in energy - such as metering fees or
  grid-operator handling "charges - into a single amount. Applied after the percentage-based
  deduction, i.e. it reduces the price by a flat amount per Wh rather than by a share of the
  raw price.
- elecfee_feedin_percent_amt:
  Total percentage deducted from the raw feed-in price (spot price) [%]. This is the
  accumulation of all percentage-based deductions payable on the feed-in tariff - such as a
  marketing or balancing fee retained by the aggregator - into a single percentage. It is
  applied as `raw_price * (100 - percent) / 100`, i.e. it scales down the raw price rather
  than adding a surcharge to it.

A new _apply_fee() method is added to the base class for ElecPrice and FeedInTariff to be used to
add the fees in a consistent way. Fees are taken from the active ElecFee provider and applied
to the raw prices given to the _apply_fee() method.

The optional application of fees is added to:

- ElecPriceAkkudoktor
- ElecPriceFixed
- ElecPriceEnergyCharts
- ElecPriceSMARD
- FeedInTariffEnergyCharts
- FeedInTariffFixed
- FeedInTariffSMARD

The import providers ElecPriceImport and FeedInTariffImport do not apply fees by intentention.

The following providers currently do not handle fees defined by ElecFee:

- ElecPriceTibber
- FeedInTariffAkkudoktor
- FeedInTariffDvhubOnline
- FeedInTariffTibber

The tests for this feature are either added or existing tests are extended.

The documentation was extended for the electricity fee provider settings.

Besides this feature further improvements are added:

* feat: add SMARD quarter-hour electricty price and feed-in tariff provider

* feat: to_series method for TimeWindows and ValueTimeWindows

  Additional to to_array the time window sequence can now also produce a pandas series.
  Test have been extended to cover the series generation.

* feat: use time windows in fixed feedin tariff provider

  Feedin tariff can now be configured by time windows - not a single value.

* feat: EOSdash select for PVLib inverters and modules

  Provide PVLib inverter and module names in config selection.

* feat: EOSdash lazy select for big option sets

  Add a new form for lazy selection of big option sets. Filtering and
  generation of the option set is done server-side.

* fix: use raw data for ETS/ median prediction

  Use to raw time series data for ETS/ median prediction to avoid interference
  by e.g. dynamic grid charges.

* fix: EOSdash config drops by type only on details resolve

  Drop configuration by type and path. Prevents dropping of configuration items
  with same type and level but different path.

* fix: EOSdash configuration section closes on update

  Open section if searching or if last update touched this category — including
  updates on deeply nested sub-fields.

* chore: make elecfeefixed, elecpricefixed and feedintarifffixed warn about no windows and default to 0

  Missining configuration creates default 0 value and a warning instead of an exception.

* fix: test setup for providers

  Reset db state on each test run.

* chore: improve config option naming for elecpricefixed.

* chore: adapt elecpricefixed test to changed time_windows naming

* chore: factorized common price provider helpers to priceabc.py

  Factorized common price provider helpers to priceabc.py. Add tests for these helpers.
  Reduce/ change testing of elecpriceabc.py and feedintariffabc.py to cover
  only specifics. Rest of testing is already covered by test_priceabc.py.

* chore: update version

Bobby NoelteandGitHub 894790f577 feat: add pvlib pv forecast provider (#1214)
Add a PV forecast provider that calculates the forecast using a PVLib system model
and weather forecast from the EOS weather forecast provider.

Additional module and inverter models can be easily added as the database
is build from PVLib and SAM databases and a bundled csv file.

The module model and inververt model names are provided by new endpoints
to be used in configuration.

The provider is based on the fantastic work of EMHASS. See
https://github.com/davidusb-geek/emhass/blob/master/src/emhass/forecast.py

A short description of the provider is added to the documentation.

Besides the new features there are the fixes and improvements:

* feat: improve EOSdash config page

* fix: kex_to_series for start_datetime

  Make key_to_series always start the series at start_datetime.

* fix: default provider for GENETIC and GENETIC0 optimization

  To make the default less dependent on internet servers (with API changes and
  availability issues) the default for PVForecast is set to PVForecastPVLib
  and for ElecPrice to ElecPriceFixed. The default weather provider is changed
  to OpenMeteo.

* fix: EOSdash display resampled prediction values

  Make EOSdash display resampled prediction values where  resampling fits to
  the prediction value type. Use bar width that fits to 15 minutes value samples.

* chore: add a UI hints system to EOSdash

  The UI hints system eases the definition of forms for configuration items.
  There are also forms for items in maps and lists. These forms allow to add and delete
  items to/ from  maps and lists. The forms ensure that all required fields of newly
  added items are filled.

* chore: Create an enum for valid optimization algorithms

* chore. Make config also provide the available energy management modes.

  Used for configuration hints.

* chore: Randomize default device id in configuration
