On-Line Voltage Security Assessment of the Hellenic Interconnected System

This paper describes the on-line Voltage Security Assessment environment developed within the framework of the EU-sponsored OMASES project, as well as its application to the Greek Interconnected Power System. The heart of all computations is a fast time-domain method. Security is analyzed with respect to power transfers in critical corridors or power consumption in load areas. Results take on t...

Power Snapshot Analysis: a New Method for Analyzing Low Voltage Grids Using a Smart Metering System

The subject of this paper is to describe the method newly developed within the research project ISOLVES (Innovative Solutions to Optimize LV Electricity Systems). The objectives are to study LV grids in detail and to close gaps of knowledge about impacts on voltage levels caused by asymmetric load or feed, and real grounding systems. Therefore a smart metering system (AMIS-Siemens) has to be up...
