Unnecessary term in N-1 reserve constraint
The following lines are already in q_resDemand so they should not appear anymore in q_resDemand_Infeed:
// Reserve demand increase because of units
+ sum(nuft(node, unit, f, t)${p_nuReserves(node, unit, restype, 'reserve_increase_ratio')}, // Could be better to have 'reserve_increase_ratio' separately for up and down directions
+ sum(gnu(grid, node, unit), v_gen(grid, node, unit, f, t)) // Reserve sets and variables are currently lacking the grid dimension...
* p_nuReserves(node, unit, restype, 'reserve_increase_ratio')
) // END sum(nuft)
