Abstract: |
In this paper a combined optimization of a
coupled electricity and gas system is presented. For the
electricity network a unit commitment problem with optimization
of energy and reserves under a power pool, considering
all system operational and unit technical
constraints is solved. The gas network subproblem is a
medium-scale mixed-integer nonconvex and nonlinear
programming problem. The coupling constraints between
the two networks are nonlinear as well. The resulting
mixed-integer nonlinear program is linearized with the
extended incremental method and an outer approximation
technique. The resulting model is evaluated using the
Greek power and gas system comprising fourteen gas-fired
units under four different approximation accuracy levels.
The results indicate the efficiency of the proposed mixedinteger
linear program model and the interplay between
computational requirements and accuracy. |
