The recent attention towards research and development in cyber-physical energy systems has introduced the necessity of emerging multi-domain co-simulation tools. Different educational, industrial efforts have been set to tackle topic from several perspectives. majority previous works addressed standardization models interfaces for data exchange, automation simulation, as well improving performance accuracy setups. Furthermore, domains interest so far involved communication, control, markets...
In modern power systems, reliable provision of grid services (e.g., primary and ancillary services) are highly dependent on automation systems in order to have monitoring, processing, decision making communication capabilities. The operational flexibility is essential for the operation during after disruptive events. However, this restricted by integrated hardware-software platforms. Therefore, it will be difficult reconfigure control strategies run time. This paper presents concept Grid...

Certain distributed computing systems require a single device to transmit identical data sets two or more devices in local area network (LAN). This kind of transmission can be achieved by using either connection oriented protocol such as control protocol/internet (TCP/IP) connectionless protocol.
