“…Therefore, power disturbances on the sources/loads and topology changes on the network are more likely to cause line overloads and cascading failures, resulting in collapse of the restored system again. Moreover, the large-scale centralised and distributed new energy power may act as a self-starting power source or a power source to be started due to the substitution of the new energy units for the traditional thermal power generators [18,19]. The output fluctuations of the new energy units are likely to cause a wide range of power flow transfer during PSR [20].…”

Disturbance-resisting ability (DRA) of the restored network needs to be considered when making a restoration scheme of power systems, to ensure system security and reduce secondary blackout risk. This paper proposes an optimisation method of whole-process restoration decision-making with DRA of the restored network in consideration. Firstly, a load rate balance (LRB) index of the restored network is defined to represent the DRA index during restoration. Then, an optimisation model of whole-process restoration decision-making is established, considering the LRB index of the restored system. To solve the model by a linear programming method, the non-linear terms in the model are transformed into linear forms. Finally, a time-step decoupling method to reduce solving difficultness of the established model with the LRB index is derived, with purpose of accelerating the solving process. The numerical results of the IEEE 30-bus system and a practical power system verify effectiveness of the proposed method to obtain a restoration scheme to balance the system restoration benefit and security. INTRODUCTIONIn recent years, a number of blackouts have occurred around the world, for example, the 11.4 Western Europe blackout [1], the 7.30 and 7.31 India blackouts [2] and the 3.21 Brazil blackout [3]. The relative post-event analysis reports show, during the power system restoration (PSR) process, that it is necessary to coordinate the progresses of the source, network and load restoration, in the meantime to enhance ability of the restored system to resist the secondary failures and the power disturbances on both the source and load sides. Otherwise, the restored system may suffer a blackout once more due to the secondary failures. Therefore, it is of great importance to enhance disturbance-resisting ability (DRA) of the restored system against the internal and external disturbances for secure and rapid restoration.

“…The proposed indices can be divided into two groups. The first group of classified indices is defensive indices which are: reactive power margin of DFIG according to the output reactive powers of stator and inverter presented in (6), wind power curtailment in severe events like wind storms presented in (7), dynamic var source margin presented in (8), load shifting due to demand response (DR) programming according to the peak load demand presented in (9), and steady-state voltage stability based on the voltage collapse proximity indicator presented in (10). The second group of indices is restorative ones which are: WT voltage violation in temporary cut-off states presented in (11), short term voltage stability by considering the probability of contingencies presented in (12), rotor angle devi-FIGURE 6 A generic fragility curve [67].…”

“…In [77], the proposed scheme is such that the power exchange between networked micro grids (NMGs) flows from the outer layer to the inner layer and only, the outer layer exchanges electricity with the power grid. In [7], according to the proposed strategy, the battery ESSs and the output of WTs are controlled in such a way that the lack of energy is compensated by batteries. Due to the importance of load and components in resilience studies, some articles have dealt with the importance of load [71] and components [57,60].…”

Recently, due to the increase of the frequency of high impact low probability (HILP) events (manmade and natural events), assessment and enhancement of resilience has become very important in the operation and planning procedures of future power systems. In this regard, several researches have been conducted on operation and planning strategies of the power system to improve resilience. Here, assessment and enhancement approaches of power system resilience by focusing on the role of wind farms and wind turbines are reviewed. To do so, a comprehensive review of the related metrics, hazard types, modelling approaches, assessment methods, and enhancement solutions is presented. Then, the assessment and enhancement methods of power system resilience are categorized in three phases before event (preventive proactive actions), during event (corrective active actions) and after event (restorative reactive actions) from the point of view of operation and planning actions. Finally, the current challenges, research gaps and future trends are discussed.
