“…The final and smallest set of articles in this taxonomy is review articles that focused on reliability evaluation of HL2. Only one article [142] discussed the reduction technique directly or indirectly related to the adequacy equivalents of HL2. Another article [143] in this category focused on the important factors and considerations required to conduct an adequacy assessment of a wind-integrated HL2 system.…”

Power systems has been subjected to significant upgrades in terms of structure and capacity. Reliability evaluation of composite power systems has surfaced as an essential step in operation and planning stages of the modern power system. It is an effective tool to investigate the ability of power systems to supply customers with reliable power service. The purpose of this review is to enhance the knowledge of reliability studies conducted on composite power systems by providing a critical and systematic review. This work investigates peer-reviewed articles published between 2007 and 2017 in three reliable databases. The findings reveal that the reliability of composite power systems has received considerable attention over the last few years. Secondly, investigation studies demonstrated a crucial role in verifying the impact of adopting new technologies. Third, studies on this topic have been intensively conducted in Asia, which highlights the promising sectors in these regions. However, researchers have generally focused on developing several aspects (e.g., evaluation speed and wind power integration) at the expense of others (e.g., realistic studies and other renewable energy resources). The lack of practical applications is evident in the surveyed publications. These findings imply a potential incoordination between the needs of the real applications and researchers’ tendencies. Future reliability evaluation scholars are advised to consider the findings of this systematic review including concentrating on insufficiently covered topics and enhance the coordination among the efforts devoted in this area.

“…The shortcoming of this process is that it is representing the base case with only a snap shot of the system. As soon as the operating condition is changing it is diverging form the base case and greater deviation from base case condition leads to less precision [1,2]. For better accuracy the boundary bus can be visualized as a range denoted by buffer zone rather than considering it as a single point and this buffer zone can shift its boundary based on different cardinal points [8].…”

This paper describes a new approach to update network equivalents by exchanging essential operational information between different cardinal points of the demand curve. The purpose of the study is to create an off-line model that has closer agreement with the on-line model of GB system. In order to minimize the setup time for analyzing the network, it needs to be represented with minimum modelling components whilst still modelling the network without compromising the security standards and other grid obligations. The proposed technique is an extension of handling the Extended Ward equivalent without requiring any real time data from the external control areas. The paper also presents the results of the tests performed to illustrate the effectiveness of the approach. Index Terms--Extended Ward Equivalent, Cardinal Points, External Network, Offline Model, GB Power Network, National Grid (NG), Low Voltage (LV) Network, Distribution Network Operator (DNO), Off-line Transmission Analysis (OLTA), National Demand Data (NDD) I.

“…Although some guidelines [7,12] are available, studies related to the impact of network reduction on fault level analysis are very rare. With regard to this problem network equivalencing is investigated and the established, Extended Ward method has been employed [3].…”

The novel technique proposed in this paper is a further enhancement of the Extended Ward Equivalent (EWE) model that does not require any real time data from the external control areas. The proposed technique will enhance LV network equivalent models in order to improve the accuracy of GB power system operational planning. The paper also presents the fault level results as related to the novel network modelling of a specific part of the GB power system in order to illustrate the effectiveness of the approach.
