Portuguese Journal of Management Studies, XII(2):133-144http://hdl.handle.net/10400.5/10011This paper presents a grid computing approach to parallel-process a neural network time-series model for forecasting electricity market prices. A grid computing environment introduced in a university computing laboratory provides access to otherwise underused computing resources.The grid computing of the neural network model not only processes several times faster than a single iterative process, but also provides chances of improving forecasting accuracy. Results of numerical tests using real market data on twenty grid-connected PCs are reported.engGrid computingelectricity marketpricesforecastingneural networksjournal article
