“…Based on the current list of power stations, generation capacities, and voltage ratings of transmission lines given in [66], and inspired by the network diagrams of the IEEE test systems [67], we develop an approximated SaskPower grid map, as shown in Figure 3. The information on the bus topology of the SaskPower grid and the connecting buses to other territories out of Saskatchewan, Canada, shown in Figure 3, are obtained from the single‐line power diagrams of SaskPower subsystems and the system descriptions presented in [68–71]. The majority of the system load and the generation fleet of the province is located in the central/southern area.…”

False data injection (FDI) attacks tamper with the state estimation data and can pose significant threats to the smart grid. The vulnerability analysis and defence strategies may help to mitigate the impact of these attacks. However, existing research efforts have not addressed the computational power and accuracy issues in the vulnerability analysis and defence mechanisms using realistic test environments. In this work, the authors present a novel low-complexity FDI attacks model to perform the vulnerability analysis. The authors develop a reduced-row-echelon-form-based greedy algorithm using the non-linear power flow system to generate FDI attacks more accurately. Later, the authors propose a novel optimal defence strategy by developing a greedy algorithm. The authors' algorithm finds the optimal power assets' locations and defends against hidden FDI attacks with low computation cost. Finally, the authors utilize the proposed AC-based attack and defence models to identify secure sites for distributed generation (DG) in the smart grid. The authors' experimental results for various IEEE standard test systems show enhanced accuracy of the attack and defence algorithms. The authors also validate the effectiveness of the proposed approaches in finding secure sites for DG units in the smart grid.

Teaching power system relaying is a fundamental issue in a power system high-level course.However, for an effective instruction of this topic an experience with real equipments can be considered as fundamental. To achieve this purpose, in this paper a new approach for the practical learning of power system relaying is presented. This consists of a computer-based testing system of relay-operating characteristic. Different relay types and developed specific software are also an important piece of the laboratory practice. Using this system it is possible to understand the performance and limitations of different protective relay systems and to test a real relay disoperation. The benefit of using this system is not available through traditional lectures and textbooks. ß

“…Another possibility is slowly changing the currents keeping the voltages constant until the operating boundary at a given angle is found. However, it is well known that the dynamic characteristic of a distance relay is different from steadystate characteristic [3,4,5]. Therefore, dynamic tests are normally used in test protection [2,6,7,8,9,10].…”

Abstract-This paper describes a power amplifier system for testing of distance relay operating characteristic. This power amplifier is based on two three phase inverters with a neutral wire. The output power currents and voltages are controlled by a sliding mode controller. A developed matlab/simulink digital simulator generates the test signals. This test signals are converted in current and voltage references using a microcontroller to connect the digital simulator to the power converter amplifier. Experimental results from a laboratory prototype are presented and discussed.
