Abstract
In present work, the MOALO applied to solve dynamic economic dispatch problems with valve point effect and with and without loss of transmission. The proposed method repository in first used to search for optimal solutions of the generated powers and then calculate the cost function. The dynamic problem of economic distribution (DEDP) is a major problem in power systems. This consists of a valve point effect, a load, a power balance and generator constraints. This method was applied to two test systems with 5 and 10 generators with different constraints. The results obtained are compared to those found in the literature. All simulations are performed on the MATLAB-Simulink platform.
