the major problem of wind turbines is the great variability of wind power production. the dynamic change of the wind speed returns the quantity of the power injected to networks. therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. in deregulated power systems, the scheduling problem has various objectives than i...

In this paper, a new nature inspired and efficient algorithm based on flower pollination is proposed for solving the optimal reactive power dispatch (ORPD) problem. The proposed algorithm is simple, easy to implement and with less number of parameter to be tuned. ORPD is an important power system optimization problem for improving the stability of the system. Loss minimization objective based O...

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...

The main purpose of this research is to determine the generation quantity of each generator in a power system. In this way, not only will the electricity demanded by the system be supplied, but the cost of fuel along with the level of pollution can be minimized. Obviously, calculation of the optimal layout of power plants with the aim of minimizing fuel costs and pollutants level contributes to...

In the practical power system, power plants are not at the same distance from the centre of load and their fuel costs are also different. Generally the power generation capacity is more than the total load demand and losses under normal operating conditions. Thus there is a need to find an effective real and reactive power scheduling to power plants to meet load demand as well as to minimize th...

This paper proposes a novel adaptive range composite differential evolution (ARCoDE) algorithm to efficiently and accurately solve optimal reactive power dispatch (ORPD) problem. Because of strategy for control parameters, the proposed ARCoDE possesses superior exploration exploitation capabilities that can handle ORPD problem involving complicated constraints discrete continuous variables. has...
