This paper presents the use of the improved harmony search method for solving economic load dispatch problems. The harmony search method mimics a jazz improvisation process by musicians in order to seek a fantastic state of harmony. To assess the searching performance of the proposed method, a six-unit thermal generating system acquired from the standard IEEE 30-bus test system was challenged. ...

Allocation of optimum active power is a backbone of power system generation planning and its high impact contribution is the need of current electrical utilities and power engineers need to browse this area in short and long term planning scenarios. Power demand requirements mapped to economic feasible solutions matching voltage profile, power demand, minimization of losses, voltage stability a...

Economic Load Dispatch (ELD) belongs to a non-convex optimization problem that aims reduce total power generation cost by satisfying demand constraints. However, solving the ELD is challenging task, because of its parity and disparity The Pigeon-Inspired Optimizer (PIO) recently proposed algorithm, which family swarm intelligence algorithms. PIO algorithm has benefit conceptual simplicity, prov...

This paper presents a review of the achievements of the optimal power dynamic dispatch problem since its inception to the present. There exist two formulations for this problem in the literature. The first formulation is the optimal control dynamic dispatch (OCDD), where the power system generation has been modelled as a control system and optimization is done in the optimal control setting wit...

In this paper we have proposed a control technique for the automatic generation control of multi generating power unit of the interconnected power system. This technique established the relationship between the economic load dispatch and load forecasting mechanism to the classical concepts of the load frequency control (LFC). The LFC system monitors to keep the power system frequency at nominal...

The Economic Load Dispatch problem concerns the determination of the optimal combination of power generators’ outputs with the lowest generation cost for a defined level of load. The problem arises from the fact that there are rated limits of generators’ power output, fuel costs of power plants are different, energy should be balanced, and plants are not located at the same distance from load c...

The paper investigates the performance of proposed search technique for different kinds of economic dispatch problems by searching generation pattern of committed units in polar coordinate system being projection of phasor on real axis with respect to its displacement. A slack generator is introduced to meet the demand constraint while generation pattern is searched within operating limits of g...
