In original opf.py there is something related to start_up_cost and shut_down_cost:
## Start up cost
rhs = LExpression(
[
(suc, network.model.generator_status[gen, sn]),
(-suc, network.model.generator_status[gen, snapshots[i - 1]]),
]
)
lhs = LExpression([(1, network.model.generator_start_up_cost[gen, sn])])
sucs[gen, sn] = LConstraint(lhs, ">=", rhs)
l_constraint(network.model, "generator_start_up", sucs, list(suc_gens), snapshots)
# Shut down cost
rhs = LExpression(
[
(-sdc, network.model.generator_status[gen, sn]),
(sdc, network.model.generator_status[gen, snapshots[i - 1]]),
]
)
lhs = LExpression([(1, network.model.generator_shut_down_cost[gen, sn])])
sdcs[gen, sn] = LConstraint(lhs, ">=", rhs)
l_constraint(network.model, "generator_shut_down", sdcs, list(sdc_gens), snapshots)
## objective
def define_linear_objective(network, snapshots):
objective.variables.extend(
[
(1, model.generator_start_up_cost[gen, sn])
for gen in suc_gens_i
for sn in snapshots
]
)
objective.variables.extend(
[
(1, model.generator_shut_down_cost[gen, sn])
for gen in sdc_gens_i
for sn in snapshots
]
)But in linopf.py, there is no "start_up_cost" or "shut_down_cost" or related objectives.
It seems the two models (pyomo=True/False) will behave differently when it comes to UC problem.
By default we will assume linopf.py is just a rewrite/re-implentation of opf.py, with same constraints and objectives.
Error Message
If applicable, paste any terminal output to help illustrating your problem.
In some cases it may also be useful to share your list of installed packages: conda list.
