An efficient Unit Commitment (UC) plays an important role in the economic operation of a power system. The generation planning mainly concerns with the short-term generation scheduling, i.e. unit commitment, which determines the optimal set of generating units to be used over a time horizon of a day or a week. The UC problem has commonly been formulated as a nonlinear, large-scale, mixed-intege...

In this paper, a dynamic generation scheduling model is formulated, aiming at minimizing the costs of power generation and taking into account the constraints of thermal power units and spinning reserve in wind power integrated systems. A dynamic solving method blended with particle swarm optimization algorithm is proposed. In this method, the solution space of the states of unit commitment is ...

this paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. a modified objective function associated with a new start-up cost term is introduced in this paper. the proposed method is used to solve generating scheduling problem satisfying srr, minimum up and down time as well as ramp rate constraints. two case studies are conducted to implem...

In this paper, a conventional thermal power plant with single stage reheat turbine is taken into consideration. It is equipped with AVR, IEEE type dual input PSS3B and integral controlled AGC loop. A hybrid distributed generation (DG) system consisting of wind turbine generators, aqua electrolyzer, fuel cells, diesel engine generator, flywheel energy storage system and battery energy storage sy...

The generation of electricity from solar thermal source has continued to garner more attention due to the very attractive environmental performance, the applicability to small distributed users and as alternative to the fossil fuels power generation. Indeed, solar thermal energy, through the coupling with ORC systems, becomes fit for electric power generation as well and, with a proper thermal ...

The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained. The temperature distributions along certain parts of the plate, which was subjected to heat generation and constant thermal conductivity condit...
