Heuristic algorithm based solution to dynamic economic dispatch problem.

The krill herd (KH) approach is proposed in this article for tackling the dynamic economic dispatch (DED) issue with valve point loadings (VPL). The purpose of resolving the DED problem is to find the optimum feasible combinations of output powers of all committed generators within a given time period while simultaneously meeting dynamic operational constraints and satisfy the total load. With the addition of valve-points in the generator cost characteristics, the DED issue becomes an inherently non-linear and non-convex issue and the DED is going to be more complicated when losses are taken into account. KH is a swarm-inspired algorithm based on krill individual herding behaviour. KH employs two global and local tactics and these works in parallel, making KH an efficient evolutionary technique. The suggested technique was tested on DED systems with 6 and 15 units, and the findings showed that the KH is effective at solving DED issues. [ABSTRACT FROM AUTHOR]
