This paper proposes a new network-based cyber intrusion detection system (NIDS) using multicast messages in substation automation systems (SASs). The proposed network-based intrusion detection system monitors anomalies and malicious activities of multicast messages based on IEC 61850, e.g., Generic Object Oriented Substation Event (GOOSE) and Sampled Value (SV). NIDS detects anomalies and intrusions...
Power system restoration is important for system planning and operation. It enables a grid to be restored from major outages efficiently and safely. The restoration process can be divided to three stages: starting generators, establishing transmission network, and restoring load services. After determining the start-up sequence of generating units, it is critical to find the shortest transmission...
Smart grid heavily relies on Information and Communications Technology (ICT) to manage the energy usage. The concept of smart grid implies the use of “smart” devices, such as smart meters or Remote Terminal Units (RTUs), that require extensive information to optimize the power grid. As the communication network is based on TCP/IP and Ethernet technology, new cyber vulnerabilities are introduced that...
Black start (BS) capability assessment is important for system planners to prepare the power system restoration (PSR) plan. To achieve a faster restoration process, installing new BS generators can be beneficial in accelerating system restoration. While additional BS capability does not automatically benefit the restoration process, power systems have to update the PSR plan and quantify the benefit...
The proposed testbed of the cyber‐power system consists of power system simulation, substation automation, and the SCADA system. Scenarios for substation cyber security intrusions and anomaly detection concepts have been proposed. An attack tree method can be used to identify vulnerable substations and intrusions through remote access points. Specific substation vulnerability scenarios have been tested...
