|Solution concept||Partial equilibrium (price elastic demand)|
|Solution method||Linear optimisation|
(Stochastic and myopic runs are also possible)
The model base year is 2005 with data taken from IEA Energy Balances.
The model time horizon is 95 years (2005-2100) with 5 year time steps up to 2070 and with 10 year time steps beyond. Each year is divided to six time slices + an additional peaking constraint.
Demand fractions (see Table 1.2) determine the fraction of service demand to be met during a specific period of the day in a given season (or timeslice).
The temporal resolution is determined by three seasons, summer, winter and intermediate. Each of the seasons accounts for a third of the whole year or 4 month. These timeslices are again split into night and day, where day represents 16 hours and night 8 hours (Table 1-2).
Therefore there a six timeslice possibilities of:
- intermediary day,
Table 1.2: Fraction of energy-service demands
|Time slice||Month share||Day share||Fraction|
|ID||0.333 (4 months)||0.666 (16 hours)||0.223|
|IN||0.333 (8 hours)||0.111|
The model is generally run with perfect foresight but can be run as myopic or stochastic though this is generally not the case.
