Dynamic multi-period economic dispatch for large-scale power systems is considered. The formulation presented caters for loading and deloading rates, limits on generators outputs, spinning reserves requirements and group power import-export limits. It is also suitable for implementation within a constraint relaxation strategy. The solution algorithm is based on a Dantzig-Wolfe decomposition, which yields a capacitated transshipment subproblem along with a master problem solved by the Revised Simplex method.The computational efficiency of the algorithm renders it suitable for on-line dispatch.

The thermal Economic Dispatch (ED) consist of a complex optimization problem of power systems planning and operation that aims to minimize the overall generation cost. The realistic representation of the thermoelectric power units is modeled by practical constraints comprising valve-point eect, multiple fuels and Prohibited Operating Zones (POZ), which makes the ED a nonconvex and discontinuous mathematical programming problem. This paperis proposes an Enhanced Bat Algorithm (EBA) to solve the ED problem with its practical constraints. The EBA is developed to improve the exploration of the search space through some modications in the original Bat algorithm (BA), with the purpose of increasing the eciency in nding good solutions for large scale ED problems. Case studies with statistical analysis are performed to assess the proposed approach, involving a system with all practical constraintsrelated to the ED problem, which is a contribution of the present paper.
