This paper presents an artificial neural network (ANN) based frequency controller design for multi-area Automatic Generation Control (AGC) scheme in a deregulated electricity market. The effect of Superconducting Magnetic Energy Storage (SMES) unit has also been considered to develop the model. SMES units have been used to the power systems to inject or absorb active power. The effect of generator...
This paper presents the design of fuzzy logic power system stabilizers using genetic algorithms in multimachine power system. In the proposed fuzzy expert system, generator speed deviation and acceleration are chosen as input signals to fuzzy logic power system stabilizer. In this approach gains, centers of membership functions and the parameters of the fuzzy logic controllers have been tuned using...
The optimal performance of power system stabilizers (PSSs), in multimachine power systems, depends highly on their parameters, location and number. This paper presents an approach of simultaneous optimization of PSS parameters, location and number in multimachine power systems based eigenvalue multiobjective function and solving using genetic algorithms (GAs). This approach permits to avoid using...
This paper presents a review of many previous papers on the use of genetic algorithms (GA) for solving the problem of economic load dispatch (ELD) for power systems. The paper will cover several topics, i.e. a brief description of the GA method, the various power system models and topologies solved by the GA method, various GA techniques used for ELD, and hybrids of GA with other techniques for solving...
In this paper, an optimal approach based on genetic and simulated annealing algorithm (GASA) is prosposed to design more effective and robust subsynchronous damping control (SSDC) of Static Var Compensator (SVC) for multimodal SSR damping improvement. A practical multi-machine series compensated power system suffering multimodal SSR has been studied to demonstrate the effectiveness of the approach...
The measure of reactive power optimization of main power network mainly considers on-load tap changer, the optimal capacity of the capacitor, the voltage of generator under the steady load. Reducing active power loss is considered of the main object function. The model of reactive optimization is established based on these. And the penalty function is considered to deal with variables violating the...
This paper presents a new approach for designing a Fuzzy Logic Power System Stabilizer (FLPSS) such that it improves both transient and dynamic stabilities. An approach for optimizing the normalization and de-normalization factors of FLPSS using Genetic and Evolutionary Algorithm has been presented. Studies have been carried out considering FLPSS based on 3,5 and 7 MFs of Gaussian shape. Investigations...
