Abstract:-Dynamic Economic Load Dispatch (DELD) is a critical optimization problem in modern power
systems, aiming to schedule generator outputs over multiple time periods at minimum cost while obeying
operational constraints. This review examines recent developments in applying Artificial Neural Networks
(ANN) to solve the DELD problem. We first outline the DELD formulation and its dynamic constraints (like
generator ramp limits). We then discuss ANN-based solution techniques, highlighting their strengths (such as
handling nonlinearity and fast computation) and limitations (such as training data requirements and
constraint enforcement). A comparative analysis is presented between ANN approaches and other AI-based
methods – notably Genetic Algorithms (GA), Particle Swarm Optimization (PSO), and hybrid techniques – to
underscore performance differences in convergence speed, accuracy, and practicality. Also explore
applications of ANN-driven DELD in smart grids, including integration of renewable energy sources and
electric vehicles, where ANN models facilitate real-time dispatch under uncertainty. Recent simulation
studies (primarily in MATLAB) are reviewed to demonstrate the effectiveness of ANN models, and key
challenges (convergence reliability, solution accuracy, real-time performance) are identified alongside
trends from current literature. The paper is organized into sections covering introduction, literature survey
of ANN in DELD, comparative analysis with other methods, simulation tools and case studies, and
conclusions.
