    Topic: Indicators plus LaggedValue slowing down calculations and codingSubscribe | Previous | Next
  • Johannes Eckstein 3/5/2021

    Dear all,

    I am experiencing problems when using indicators and laggedvalue. Concretely, I am trying to implement the eurostat RES-E method, which requires using values 14 years prior to a year in question. LEAP returns zero when referencing a result variable prior to the base year, so some lines of code are required to catch this.

    It seems that using LaggedValue in the indicators slows down LEAP. When I submit such a line of code, cpu heavy background calculations start and I have to wait until these finish. These background calculations also start when I click on such an indicator in the analysis view. Before using the If( Year >= BaseYear+8; -clauses, these expressions also seemed to keep LEAP from completing calculations for results.

    Including the If( Year >= BaseYear+8; -clauses reduced the calculation time. What else could I do to reduced this?

    EDIT:
    I've now moved the creation of the lagged timeseries to a set of other variables and exchanged the calls to LaggedValue with subsequent calls to prevYearValue (one year lag using prevyearvalue on the original, two year lag using prevyearvalue on the one year lagged, etc). So I now longer called laggedvalue and the number of calculations is possible reduced while the number of variables grows. This reduces background calculation time further but working with the indicators is still rather tedious due to the calculations that start each time I try to edit the relevant indicators.

    Many thanks in advance for considering to support.

    Best regards,
    Johannes

    This is the main indicator referencing others. It is again referenced by an indicator to calculate RES-E shares, which is again used to calculate other indicators.

    Transformation\Electricity Production\Processes\Hydro:Capacity[MW] *
    If(
    year > BaseYear+14; Indicators\RES E time hydro\avg 14:Indicator[kh] ;
    year > BaseYear+13; Indicators\RES E time hydro\avg 13:Indicator[kh] ;
    year > BaseYear+12; Indicators\RES E time hydro\avg 12:Indicator[kh] ;
    year > BaseYear+11; Indicators\RES E time hydro\avg 11:Indicator[kh] ;
    year > BaseYear+10; Indicators\RES E time hydro\avg 10:Indicator[kh] ;
    year > BaseYear+9; indicators\res e time hydro\avg 9:indicator ;
    year > BaseYear+8; indicators\res e time hydro\avg 8:indicator ;
    Transformation\Electricity Production\Processes\Hydro:Capacity[MW] > 0; Indicators\RES E time hydro\avg 00:Indicator[kh] ;
    0) / Demand:Energy Demand Final Units[GWh| Fuel=Electricity] * 100

    This is one of the indicators referenced above (indicators\res e time hydro\avg 8):

    If( Year >= BaseYear+8;
    If(LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 8) > 0; (Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh; Fuel=Electricity] / Transformation\Electricity Production\Processes\Hydro:Capacity[MW] +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 1) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 1) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 2) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 2) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 3) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 3) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 4) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 4) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 5) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 5) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 6) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 6) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 7) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 7) +
    LaggedValue(Transformation\Electricity Production\Processes\Hydro:Outputs by Output Fuel[GWh| Fuel=Electricity]; 8) / LaggedValue(Transformation\Electricity Production\Processes\Hydro:Capacity[MW]; 8) ) / 9;
    0);
    0)
