Due to the incremental demands for electrical energy, Distributed Generator (DG) sources are prominent in distribution systems. At the same time, the Locations and Capacities of DG sources have profoundly influenced the system losses in a distribution network. In this paper, a Hybrid algorithmusing Power Loss Index (PLI) & Genetic Algorithm (GA) presented for optimized Location and sizing of DG...
Minimization of voltage deviations and power loss can be controlled by optimal reactive power dispatch for voltage stability of the system. This paper presents Genetic Algorithm approach for system parameters enhancement and optimal reactive power dispatch. The transformers tap changers, generator exciters, switchable VAR sources are used as control variables for improvement of system parameters....
As continuity of our previous published works dealing with improving transient stability of the superconducting generator with high response excitation (SGHRE), we have introduced in this paper fuzzy logic controllers (FLC) in the excitation and governor loops. In order to obtain optimal values of normalization and de-normalization factors, a genetic algorithm has been used (GFEG). Non-linear simulation...
The first real time task of ISO focuses on Static Congestion Management (SCM), i.e. the congestion caused by the thermal and voltage limits. When power systems undergoes discrete changes in system configuration due to outage and contingencies, the system dynamic performance will be affected and the system stability might be threatened. In this respect, the second real time task of ISO focuses on the...
The power system stabilizer can suppress the electromechanical oscillation and enhance the power system stability with the aid of its additional excitation control. The need for power system stabilizations has been increasing day by day. The demand for electric power requirement has motivated the usage of power system in an effective and reliable way. The stability of the power system is the ability...
This paper presents a study of tuning the existing power system stabilizers (PSSs) of the Saudi Electricity Company (SEC) power system and its effect on increasing the power transfer limit of the interconnection between Eastern Operating Area (SECE-OA) and Central Operating Area (SEC-COA). This work is also investigating the optimal location of installing additional power system stabilizers (PSSs)...
Fast and effective means to restore the load has a very important theoretical and practical significance after blackout. Power system is a real-time dynamic system, the constraints in current in calculation all are steady-state parameters such as steady-state frequency, steady-state voltage etc. The probable out of step and voltage collapse during the dynamic processes after load restoration cannot...
Blind equalization based on compensation fuzzy neural network has proposed. It using compensation neurons to get tradeoff between negative and active operation, thus the network can be training using fuzzy rule of initial right or wrong setting, and fault tolerance and stability are improved. Simulations results show that this algorithm has faster convergence speed and less residual error compared...
