Bad request for query_imbalace_prices about entsoe-py HOT 6 CLOSED

Hi Philipp,
If I'm not wrong, psr_type should correspond to a key in entsoe.mappings.PSRTYPE_MAPPINGS
See https://github.com/EnergieID/entsoe-py#psr-type
Best,

from entsoe-py.

The query_imbalance_prices does its lookup of the country code in DOMAIN_MAPPINGS. Germany is a weird case, because it has country code 'DE' ('10Y1001A1001A83F'), and bidding zones 'DE-AT-LU' ('10Y1001A1001A63L') up until October '18 and bidding zone 'DE-LU' ('10Y1001A1001A82H') starting October '18.

Please try your request with country_code='DE-AT-LU', I think that should work.

This issue is also discussed in part in #9, but I think the whole country/domain/bidding zone thing could be implemented better, I just don't have an elegant idea in mind right now.

I tried it with country_code = 'DE-AT-LU' but it still doesn't work. Also, I tried out several psr_types, document types and BSN types:

psr_types = {'B01': 'Biomass','B02': 'Fossil Brown coal/Lignite','B03': 'Fossil Coal-derived gas','B04': 'Fossil Gas',
    'B05': 'Fossil Hard coal','B06': 'Fossil Oil', 'B07': 'Fossil Oil shale', 'B08': 'Fossil Peat', 'B09': 'Geothermal',
    'B10': 'Hydro Pumped Storage', 'B11': 'Hydro Run-of-river and poundage', 'B12': 'Hydro Water Reservoir',
    'B13': 'Marine', 'B14': 'Nuclear', 'B15': 'Other renewable', 'B16': 'Solar','B17': 'Waste',
    'B18': 'Wind Offshore', 'B19': 'Wind Onshore',}

balance_params = {'A81': 'Contracted reserves',
                'A82': 'Accepted offers',
                'A83': 'Activated balancing quantities',
                'A84': 'Activated balancing prices',
                'A85': 'Imbalance prices',
                'A86': 'Imbalance volume',
                 'A88': 'Cross border balancing',
                'A89': 'Contracted reserve prices',
                'A95': 'Frequency containment reserve',
           'A96': 'Automatic frequency restoration reserve',
           'A97': 'Manual frequency restoration reserve',
           'A98': 'Replacement reserve'}

I always get a HTTP 400 Error response.

Are you guys getting information on Frequency Reserve Prices, quantities and volumes ?
The information that I am looking for should look like this:

Maybe the query_imbalance_prices function is not the correct one to use ?

from entsoe-py.

I tried this call

client = EntsoePandasClient(api_key=settings.api_key)

start = pd.Timestamp('20190101', tz='Europe/Berlin')
end = pd.Timestamp('20190102', tz='Europe/Berlin')

client.query_imbalance_prices(country_code='DE-LU', start=start, end=end)

and it works fine for me:

I tried it with some PSR Types though, and couldn't get it to work. Although the API-docs say that PSR type is an optional parameter for imbalance prices.

That being said:
What you show in your screenshot are not the Imbalance Prices! It is the Price of Reserved Balancing Reserve.
I didn't immediately find it in the API docs, but the API does have "Prices of Procured Balancing Reserves", and "Prices of Activated Balancing Energy".

These methods have not been implemented in the Python Client yet.

I tried Prices of Procured Balancing Reserves as a raw request:

params = {
    'documentType': 'A89',
    'controlArea_Domain': '10YCZ-CEPS-----N',
    'type_MarketAgreement.Type': 'A01',
    'businessType': 'A96'
}
response = client.base_request(params=params, start=start, end=end)
response.raise_for_status()
print(response.text)

That worked fine!

Feel free to implement additional requests from the API and create a pull request if you'd like.

from entsoe-py.

I think I will try to work with the raw requests :) If I'm free I can try to implement it in the entso-e client.

Thank you for your help!
