Stability Study and Characterization of Power Distribution Networks with Distributed Energy Resources: Case Study of the Egyptian Electric Distribution Systems With the increase of connecting distributed energy resources (DERs), distribution networks can not be seen any more as a power sink that consumes power. Hence, many software tools that are classically used to analyze transmission networks are currently required for planning and operation unbalanced three-phase distribution networks. The classical power system stability tools which have been intended to solve positive-sequence networks are not applicable for analyzing unbalanced distribution networks.

The main aim of this research proposal is to develop stability tools for analyzing unbalanced distribution networks fed from DERs as well as the transmission system. Such development requires many of new power system models and innovative solution methods and techniques. The methodology adopted to conduct the proposed research will be based on the state of the art methods and published papers in periodicals. The most suitable approaches will be selected to be the basis for the unbalanced three-phase analysis.

The developed stability algorithms will be implemented using the state of the art object-oriented and component-based software approaches. The software component suits with the industry-wide application programming interfaces (APIs). In consequence, the proposed engine can be easily integrated or reused with a third party power system software application. The testing methodology adopted to validate the proposed engine will be based on the IEEE data as well as data for distribution systems in USA and Egypt. The dissemination of the results will be through workshops, universities, industry, international conferences, journals, and patents. The outcome of this research will be in the form of a software prototype that can be used by both distribution system companies as well as academia.
