“…In contrast to existing literature that mostly focuses on overall system controllability measures [16][17][18][19], our work provides individual controller roles as well as the formalisation and application of their interactions for system F I G U R E 2 Application of SDCD with an example set of 10 distributed controllers; RID computes the control support groups and roles of the controllers. When compromise occurs, the residual, functional set, and RID results are applied to determine which controllers to respond with and using what settings.…”

Distributed controllers play a prominent role in electric power grid operation. The coordinated failure or malfunction of these controllers is a serious threat, where the resulting mechanisms and consequences are not yet well-known and planned against. If certain controllers are maliciously compromised by an adversary, they can be manipulated to drive the system to an unsafe state. The authors present a strategy for distributed controller defence (SDCD) for improved grid tolerance under conditions of distributed controller compromise. The work of the authors' first formalises the roles that distributed controllers play and their control support groups using controllability analysis techniques. With these formally defined roles and groups, the authors then present defence strategies for maintaining or regaining system control during such an attack. A general control response framework is presented here for the compromise or failure of distributed controllers using the remaining, operational set. The SDCD approach is successfully demonstrated with a 7-bus system and the IEEE 118-bus system for single and coordinated distributed controller compromise; the results indicate that SDCD is able to significantly reduce system stress and mitigate compromise consequences.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Few authors [21] have tried to define a hybrid participation factor to optimally place the FACTS controllers so as to determine a compromising optimal location to achieve both static as well as dynamic performance enhancement. However, such methods use relative weights to the static and dynamic participation factors to In this work, the static criterion used for optimal location of FACTS controllers is based on a loss sensitivity index as defined in the work of [2,3] and given as follows.…”

“…The unified power flow controller (UPFC) is used to control the real and reactive powers simultaneously in a line by injecting a series voltage across the line. It also injects a shunt reactive current at one of the line-end buses to maintain the bus voltage at a specified value [2,3]. FACTS devices are provided with supplementary controllers for damping out small signal oscillations [4][5][6][7][8], and the effectiveness of damping the oscillations depends on the location of FACTS controllers.…”

This paper proposes a residue method to find the optimal location of the FACTS controllers to damp out the inter-area mode of oscillations. Three types of FACTS controllers have been considered, which include static var compensator, thyristor-controlled series compensator and unified power flow controller. The residue method is base on the facts that it is the product of the mode's observability and controllability index of FACTS controllers to the critical mode. The placements of FACTS controllers have been obtained for the base case and placement base of loss sensitivity is also introduced. The effectiveness of the proposed method is demonstrated on two area 11 bus systems and New England 39-bus system.

An algorithm combining the power oscillation flow method with the singular value decomposition is proposed to select the installation location and input signal for the supplementary damping controller of SVCs [5,6].

This paper proposed a new algorithm to perform the online determination of the low frequency oscillation modes in large interconnected power system. First, the generator's active power and its speed deviation were represented in the form of generalized phasor and the relationship between their phase angles was deduced. Then a simple system was constructed to illustrate the correspondence between the power oscillation flows in the tie lines and the low frequency oscillation modes. Theoretical analysis indicates that different oscillation modes correspond to different phase angle combinations, and vice versa. The small signal stability of the SE Australian power system was analyzed by PSS/E. The analysis reveals that both of the operating point and modeling deepness have essentially no effect on the correspondence between oscillation modes and phase angle combinations. Finally the procedure to use the algorithm in practical power system was given, and it was applied to the Eastern China power grid. Results indicate that the algorithm proposed by this paper is able to determine the low frequency oscillation modes online and is helpful for the monitoring of low frequency oscillation.Index Terms--power oscillation flow, phase angle combination, SE Australian power system, operating point, modeling deepness, Eastern China power grid IX.
