摘要
Feedforward artificial neural networks have many properties that make them specially suited to short-term load forecasting. However, the main drawback is not having a training algorithm that finds a nearly global set of weights in a reasonable amount of time. A genetic algorithm is a robust optimization method that find solutions to problems by an evolutionary process based on natural selection. This paper presents short-term load forecasting using a genetic algorithm to optimize the weights of an artificial neural network. It also presents a technique that allows a genetic algorithm to consistently find a good set of weights for an artificial neutral network. A 12-hour power system forecast is then performed comparing the refined genetic algorithm's training algorithm, the back-propagation training algorithm, and an interior point training algorithm.
