The use of real-time instruments for smart power systems

In this paper, an architecture of a low-cost ARM-based Smart Metering network is presented. The system is designed to be suitable for Smart Grids applications aimed to a more efficient energy use according to the article 13 of Directive 2006/32/EC. The network is composed by several slave smart meters that continuously monitor loads and energy generator to make available in real-time information such as power and energy consumption/generation and several power quality parameters to a specific master device called data aggregator. This device integrating the information coming from slave smart meters and information regarding co-generator status, the forecast renewable source availability and, through a web service access, current energy prices, can take decisions to apply suitable management strategies aimed at reducing costs.
