ABSTRACT:
This paper addresses
the problem of reducing CO2 emissions by applying convex optimal power
flow model to the combined economic and emission dispatch problem. The large amount
of CO2 emissions in the power industry is a major source of global warming
effect. An efficient and economic approach to reduce CO2 emissions is
to formulate the emission reduction problem as emission dispatch problem and combined
with power system economic dispatch (ED). Because the traditional optimal power
flow (OPF) model used by the economic dispatch is nonlinear and nonconvex, current
nonlinear solvers are not able to find the global optimal solutions. In this paper,
we use the convex optimal power flow model to formulate the combined economic and
emission dispatch problem. The advantage of using convex power flow model is that
global optimal solutions can be obtained by using mature industrial strength nonlinear
solvers such as MOSEK. Numerical results of various IEEE power network test cases
confirm the feasibility and advantage of convex combined economic and emission dispatch
(CCEED).
