the paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. some mathematical vector models were obtained for control system multicriterion quality indices with due ...

Unified Power Flow Controller (UPFC) is one of the most efficient FACTS devices that can be individually or combinatorial on all effective parameters in the transmission power of the transmission lines. With the flexibility of effective parameters in power passage, the power system operation can be improved. in this study, the optimization algorithm based on location and optimal capacity of UPF...

In this paper, the integrated unit commitment problem and gas network operation in which in the presence of renewable wind and solar power plants is modeled. Both wind and solar energy are variable sources of energy, but because solar energy is only available at certain times of the day, it has caused the load curve behavior to change. This change in load curve, known as the "duck curve, has ra...

To improve the stability of the power system, the design of a PSS and STATCOM controller parameters using ABC is presented as an optimization problem in this paper. The ABC is a collective intelligence based on the optimization algorithm and inspired by the bee feeding behavior in finding food. Fast convergence and high accuracy are the capabilities of this algorithm. The effectiveness and robu...
