Solving the Model

fix_integers(jump_model::Model)

This function fixes the iteger variables ones the model has been solved in order to calculate approximations of dual variables.

Arguments

• jump_model::Model: a model object containing that has been previously solved.

Returns

nothing (modifies an existing-solved model in the memory). solve() must be run again to solve and getdual veriables

solve_model(EP::Model, setup::Dict)

Description: Solves and extracts solution variables for later processing

Arguments

• EP::Model: a JuMP model representing the energy optimization problem
• setup::Dict: a Dict containing GenX setup flags

Returns

• EP::Model: the solved JuMP model
• solver_time::Float64: time taken to solve the model
