Abstract: Economic load dispatch has used to evaluate minimum cost of power generated at the thermal plants. Economic load dispatch characteristic can be formulated in quadratic cost function, considered as linear function. The quadratic ELD cost function will be nonlinear in nature when involve the effect of valve loading. For optimization of linear as well as nonlinear cost function this work proposed a latest metaheuristic swarm based technique known as Elephant herding optimization (EHO) and modified EHO (MEHO). The EHO technique stimulated by the behavior of herding of elephant organization. EHO has the fast convergence rate due to the use of clan updating as well as separator operators. In general elephants live together under the leadership of a matriarch. According to behavior of elephants consider two type of operators namely clan updating operators and separating operators for optimization of the linear and nonlinear problems. In the present work results of MEHO is compare with EHO, ACO and PSO. The outcomes show that MEHO can find the higher values on maximum benchmark issues than the ones three meta heuristic algorithms.
