Voltage and var support in electric power systems

July 14th, 2014, Published in Articles: Energize


The present environment for the operation of electric power systems (EPS) is complicated by environmental, economic as well as societal constraints. As a result EPS operate often close to their limits while trying to minimise costs and keep the quality of supply according to standards. The picture is complicated further by new types of generation and loads, market rules, and the increasing frequency and severity of weather events.

Currently, special attention is given to the development of active distribution networks within intelligent system architectures, facing new challenges including:
