The allocation of distributed generation and capacitor banks is critical for success in the planning power grids. A methodology developed optimal placement renewable (wind photovoltaic powers) based on technical economic parameters. In order to preserve horoseasonal stochastic dependence nature wind solar power, uses a model that integrates sequential Monte Carlo method diagonal band Copula mod...

Solving the capacitor Allocation problem means in general the determination of the optimal location, allocation sizes and switching times for capacitors to be installed on a distribution feeder. The application of capacitors in electric power system is intended for the control of power flow, improvement of stability, voltage profile management, power factor correction, and loss minimisation. Th...

In this paper, the new hybrid particle swarm optimization (hybrid-PSO) based on particle swarm optimization (PSO), evolutionary programming (EP), and tabu search (TS) is developed. Hybrid-PSO is proposed to determine the optimal allocation of multi-type flexible AC transmission system (FACTS) controllers for simultaneously maximizing the power transfer capability of power transactions between g...

Reactive power management plays an essential role in the secure operation of the power system as an ancillary service. Although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. On the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the se...

In this paper, Apriori algorithm has been improved and applied to substation data mining process. Ant colony algorithm is applied to get the optimal solution of reactive power allocation in substations. The state transition probability formula is amended and parameters are dynamically adjusted in this ant colony algorithm. The choice of the ant’s path to the next node is determined by the tabu ...
