Abstract EN
Economic dispatch (ED) is of cardinal significance for the power system operation.
It is mathematically a typical complex nonlinear multivariable strongly coupled optimization problem with equality and inequality constraints, especially considering the valve-point effects.
In order to effectively solve the problem, a simple yet very young and efficient population-based algorithm named across neighborhood search (ANS) is implemented in this paper.
In ANS, a group of individuals collaboratively navigate through the search space for obtaining the optimal solution by simultaneously searching the neighborhoods of multiple superior solutions.
Four benchmark test cases with diverse complexities and characteristics are firstly employed to comprehensively verify the feasibility and effectiveness of ANS.
The experimental and comparison results fully demonstrate the superiority of ANS in terms of the final solution quality, convergence speed, robustness, and statistics.
In addition, the sensitivities of ANS to variations of population size and across-search degree are studied.
Furthermore, ANS is applied to a practical provincial power grid of China.
All the comparison results consistently indicate that ANS is highly competitive and can be used as a promising alternative for ED problems.
