Minimizing Age of Information for Distributed Control in Smart Grids

Distributed utility‐based real‐time power flow optimization in ICT‐enabled low voltage distribution grids

“…The final step in the computation of power set points is the projection onto the set of feasible DER power values according to (35) and (36). The DERs do this projection themselves, meaning that in case ṕset,c or qset,c is infeasible, they adjust their active and reactive power to the closest feasible value.…”

“…From the communication network point of view, this data exchange facilitates itself as an N -to-N broadcast problem. A generalized broadcast protocol has been introduced by the authors in [35] and is further adapted to fully support the control method presented in this paper. Disseminating information from each node to all other nodes is a challenging task for distributed multi-hop networks, as N (N − 1) different source-destination flows have to be established.…”

“…To address this, multiple source-destination flows can be disseminated simultaneously at the cost of sharing network capacity. This trade-off was analyzed in depth in [35] and since the network considered in this work only consists of relatively few nodes, we limit our evaluation to pure sequential flooding.…”

“…In addition to the seven packet types formulated in the original paper [35], the protocol is further extended for the evaluation of this work. Two additional packet types ( SKIP , RECONNECT ) are introduced to allow for nodes to leave and re‐join the sequential flooding process.…”
