Bernstein global optimization approach for distributed optimal power flow problem incorporating emission costs

This paper proposes a distributed architecture for solving the optimal power flow (OPF) problem i n power systems operation. Specifically, a centralized solution approach (to solve single optimization problem) presented in the literature is posed as solving different local optimization problems. The Bernstein global optimization approach is used to solve these local optimization problems in a co-ordinated and distributed fashion. The proposed approach is implemented on a typical 3-bus power system, wherein the cost of CO2 emissions is also considered. The overall results obtained are satisfactory.
