Adding a flag to enable time series form of transferLoss for transfer links. Changing the order of node and node_ in several places in the constraints that used p_gnn(grid, node, node, 'transferLoss').

Adding two new parameters under param_policy: reserve_activation_duration and reserve_reactivation_time. The parameters are now included in q_stateUpwardLimit, q_stateDownwardLimit and q_boundStateMaxDiff. Default value for both parameters is 1 (hour) and reserve_reactivation_time should be greater than or equal to reserve_activation_duration.

Issue #129.

Issue #137

Adding domain checking for a few parameters and sets. Removing p_gnPolicy and p_groupPolicy3D, and adding p_groupPolicyEmission and p_groupPolicyUnit. Affects input files. Issue #121.

Updating the right hand side of q_unitEqualityConstraint and q_unitGreaterThanConstraint (issue #124). p_unitConstraint should take into account the size of one sub-unit as it will be multiplied by the number of online sub-units (or 1 if the unit does not have an online variable).

new parameters added to p_groupPolicy to allow for selection of static and/or dynamic inertia constraints

One gnu_input/output fix in the constraints and updating start-up emission cost and total emission calculations (issue #107).

Taking into account reserve reliability and reserve demand feasibility dummy variables in q_inertiaMin (see issue #103).

1) Updating 1e_scenChanges.gms according to the new inputs, 2) adding a new constraint q_unitGreaterThanConstraint, and 3) fixing a few constraints to work with the invest model as well.

Removing the 'tSolveFirst = mSettings(m, 't_start')' conditions from two equations so that they would work also with the myopic invest model version. Issue #119.

Re-implementing dynamic generation portfolios (see issue #119). Unit investment variables still have the 't' dimension, although it is kind of redundant. Units have technical lifetimes (given in ut set) but links are assumed to stay in the system forever after they have been built. Cost discounting and multi-year horizons are considered in the objective function but not in the results outputting yet.

First working commit for the new inputs and outputs system. Probably buggy... In Google Drive there is 8unit system excel that works with this (vInputOutput.xlsx).

Removing q_resDemandLargestInfeedTransferUp and q_resDemandLargestInfeedTransferDown, as q_resDemandLargestInfeedTransfer can handle both.

Added new parameter `ts_energy_(s)` to which total energy is
calculated. This parameter has the sample dimension last, as required
by the SCENRED2 tool. This allowed changing all other time series
to have indices `s, f, t` instead of previous `f, t, s` and dropping
the set `fts` completely.

Fixes #105

Adding the grid dimension to the reserve parameters and variables. Changes required to the input files. Removing the obsolete nuft set. Issue #69.

Updating constraints for maximum share of reserve provision, ROCOF limit, as well as reserve demand caused by largest unit infeed and largest transfer link import/export. Testing one constraint for reserve demand caused by largest transfer link import/export (instead of two separate constraints).

First tests, disabling all reserve requirement constraints except q_resDemand. Adding some new parameters and sets (df_reservesGroup, restypeDirectionGroup, restypeDirectionGridNodeGroup) and changing the dimensions of some other parameters, sets and variables.

Updating the two ROCOF constraints so that they apply to a group of nodes instead of individual nodes.

The transfer ROCOF constraint considers failures of interconnectors with one end inside the group and one end outside the group. 'DefaultFrequency' and 'ROCOF' are now p_groupPolicy parameters instead of p_gn parameters.

First try to fix issue #97.
