The need for a flexible computing environment to support these studies is derived by the complexity of the process, the volume of data often used and the diversity of the applied tools and techniques that span many disciplines. A data warehouse can be a central component of this environment. In this paper our experience with building and using such an environment is described. Data collection and transformation tools, machine-learning tools and testing tools have been integrated in the MLPSE environment described here, used for steady state security assessment of power systems. It is argued that the proposed approach can be applied to many similar power systems analysis studies.
