We study the impact of capturing spatiotemporal correlations between multiple wind supply points on economic dispatch procedures. Using a simple dispatch model, we first show analytically that over/underestimation of correlation leads to positive and negative biases of dispatch cost, respectively. A rigorous, large-scale computational study for the State of Illinois transmission grid with real ...

In this paper, real-coded genetic algorithm with smart mutation (RCGA-SM)is proposed to solve the economic dispatch (ED) problem. In the proposed method, the required controllingprocess is accomplished on the total amount of chromosomes and consequently there is no need to use penalty cost function for controlling sum of variables in solving economic dispatch problem. This method will begin to ...

The introduction of techniques of artificial intelligence in software of control and decision is an essential element in research and development of tomorrow’s power systems. Neural networks are among the techniques most used in the field of artificial intelligence. The economic dispatch is a key sector in the electricity networks, where it must generate less energy for the same demand with goo...
