Planning and analysis tools to evaluate distribution automation implementation and benefits

The concept of distribution automation dates back to the 70´s. The main motivation was to use evolving computer and communications technology to improve operating performance of distribution systems. Efficiency improvement was the main driver of distribution automation in its initial stages. Now, distribution automation has to address enhancements in efficiency as well as reliability and quality of power distribution. This paper discusses the new tools to quantify benefits of distribution automation. These tools are able to include the functionality of new devices and the benefits provided by them. Specific tools that need attention for implementation of advanced distribution automation include tools for cost/benefit evaluation, system analysis, and reliability evaluation.
