“…First, we can reduce controller-switch latency. The latency of fewer than 2 milliseconds (found in our experiments and specified in IEC 61850 [23]) is within the range of the system invariant of seed devices. Second, we can reduce the number of switches in the communication path connecting the seed device and the packet hooking component.…”

Reconnaissance is critical for adversaries to prepare attacks causing physical damage in industrial control systems (ICS) like smart power grids. Disrupting reconnaissance is challenging. The state-of-the-art moving target defense (MTD) techniques based on mimicking and simulating system behaviors do not consider the physical infrastructure of power grids and can be easily identified. To overcome these challenges, we propose physical function virtualization (PFV) that "hooks" network interactions with real physical devices and uses these real devices to build lightweight virtual nodes that follow the actual implementation of network stacks, system invariants, and physical state variations in the real devices. On top of PFV, we propose DefRec, a defense mechanism that significantly increases the effort required for an adversary to infer the knowledge of power grids' cyber-physical infrastructures. By randomizing communications and crafting decoy data for virtual nodes, DefRec can mislead adversaries into designing damage-free attacks. We implement PFV and DefRec in the ONOS network operating system and evaluate them in a cyber-physical testbed, using real devices from different vendors and HP physical switches to simulate six power grids. The experimental results show that with negligible overhead, PFV can accurately follow the behavior of real devices. DefRec can delay adversaries' reconnaissance for more than 100 years by adding a number of virtual nodes less than or equal to 20% of the number of real devices.

In this paper, we review the functions and architectures of control centers: their past, present, and likely future. The evolving changes in power system operational needs require a distributed control center that is decentralized, integrated, flexible, and open. Present-day control centers are moving in that direction with varying degrees of success. The technologies employed in today's control centers to enable them to be distributed are briefly reviewed. With the rise of the Internet age, the trend in information and communication technologies is moving toward Grid computing and Web services, or Grid services. A Grid service-based future control center is stipulated.

“…Substation Controller also communicates with the main controller with IEC61850 protocol. Since this protocol is the state of the art substation automation protocol [8], the substation controller is designed to support this protocol and be ready for integrating to existing automation infrastructure.…”

Rapidly increasing energy demand and developing photovoltaic cell technology bring importance to integrate Renewable Energy Sources (RES) (mostly Solar Generation) in Distribution Systems in near future. Considering power quality, sustainability, and reliability as the main goals, a well-designed control and communication system with reliable and expendable infrastructure is needed. In this paper, a Communication and Control system which has been developed to control and monitor PV Generation in a LV Distribution Network is presented. IEC61850 and MODBUS TCP/IP protocols are used to gather data from field to control center. The functional aspects, performance and topology of the control and communication system are discussed.
