Unit Commitment Including Economic Dispatch with Network Constraints

Abstract

In this paper it is presented the development of an algorithm to solve two complex power systems problems at once. The algorithm carry out two steps: solve the Unit Commitment problem using a meta-heuristic with Constraint Oriented Neighborhoods and promote the base to the Economic Dispatch problem, which consists on the optimization of operating costs under the general constraints to the power system, which is solved through the use of linear programming. The algorithm was applied with success to the Mozambique electric power system, achieving good results and less execution timing consuming.
