This paper proposes differential evolution (DE) algorithm based PID controller for pitch control of the isolated wind-diesel hybrid power system. Simulation of a hybrid power system model has been carried out in a time domain analysis with a step load change of 1%. The wind and diesel power generators frequency and power deviations responses are presented and analyzed. The results are compared with...
The main objective of this paper is to accurately forecast the short-term loads using Discrete Wavelet Transform (DWT) in combination with Artificial Neural Network/ Support Vector Machine. The complete analysis has been carried out using Temperature, Humidity, Dew Point and Actual loads as features. Here, 8-level DWT decomposition has been done to extract the 8 detailed and approximation coefficients,...
Bat algorithm is a recent addition to the bioinspired algorithms, considered as a new metaheuristic algorithm based on Bat behaviour. This work presents, the optimal solution of economic load dispatch (ELD) is obtained using the proposed bat algorithm. Here the operating cost of a thermal power plant is optimized using Bat algorithm. Numerical results show that the proposed method has good convergence...
The Gravitational Search algorithm (GSA) is one of the recent additions to the new heuristic optimization algorithms based on law of gravity and mass interactions has been applied to solve the short term scheduling hydrothermal system. In the proposed algorithm, the searcher agents are collection of masses interact with each other based on the Newtonian gravity and the laws of motion. Hydrothermal...
An integrated approach combining an evolutionary programming based fuzzy coordination and an artificial neural network methods along with a heuristic rule based search algorithm has been developed in this paper in order to obtain the best compromising optimal generation schedules for multiobjective generation dispatch problem with non-smooth characteristic functions satisfying various practical constraints...
