The emergence of micro-generation systems steadily increases and it raises concerns regarding their impact on the power grid. It is therefore crucial to efficiently integrate them into future Smart Grid Architectures. Actually, there is not any standard way to monitor production units. And current data collection systems are naive and do not consider their impact on Local Area Networks. This article studies a set of proposed mechanisms that reduces the monitoring traffic, while offering management flexibility on large-scale systems. This study is illustrated with measurements performed on a small grid. It shows that, for monitoring a PV production, both one minute and one second intervals provides the same production estimation, while significantly decreasing the associated traffic. It can be reduced even more by aggregating several measurements during a given period before sending them, and by using specific mechanisms to ensure reliability. This experiment also helps authors identify best practices for monitoring different equipment based on their behaviors.
