Water Evaporation Optimization Algorithm for Solving Dynamic Economic Dispatch

This paper presents an efficient Water Evaporation Optimization algorithm (WEO) is proposed to solve a Dynamic Economic Dispatch problem (DED). The dynamic dispatch problem differs from the static economic dispatch problem by incorporating generator spinning reserve, ramp rate limits, and valve point loading and transmission losses. The proposed water evaporation optimization algorithm is based on the evaporation of a tiny amount of water molecules on the solid surfaces with different wettability which can be studied by molecular dynamics simulations. The performance of the WEO algorithm is tested on five unit system with spinning reserve and ten unit systems. The comparison of the simulation results prove that the proposed WEO algorithm have a better performance than the existing methods.
