## 1 Introduction  
Wind power plants (WPPs) have continuously evolved globally and have become a significant participant in enhancing grid operation in most countries, showcasing the immense potential of renewable energy sources [1, 2, 3, 4, 5, 6, 7, 8]. WPPs can be operated in one of two modes: standalone or grid-connected. In grid-connected mode, they provide extra power when the demand for loads in the power grid increases. In standalone mode, they act as an emergency supply for individual loads during power system outages [9, 10]. WPPs are classified as small-scale or large-scale, depending on the size of the wind turbine generator units (WTGUs) they comprise. The size of these WTGUs is based on the rotor diameter (in meters), swept area (in square meters), and the standard power (in kilowatts) produced by the WTGU. Table 1 shows the lists of different sizes of WTGUs [11]. Large-scale wind power plants (LSWPPs) comprise large commercial wind turbine generator units (LCWTGUs). On the other hand, WTGUs are classified into two by the axis at which wind turbine blades (WTs) rotate. They are horizontal-axis wind turbine generator units (HAWTGUs) and vertical-axis wind turbine generator units (VAWTGUs). HAWTGUs are the most popular class and are either upwind or downwind. Figures 1 and 2 show the upwind and downwind HAWTGUs [12]. Upwind HAWTGUs are the most popular class and are applied mostly in large-scale wind power plants (LSWPPs). The operation of LSWPPs in a grid-connected mode has been leading over the past ten years [13; 14; 15]. Many studies have been conducted regarding LSWPPs in grid-connected modes of operation. However, few studies have examined the renewable energy grid code (REGC) specifications while integrating these LSWPPs into the power grid. Among the few, none have evaluated various operating conditions of the power grid into which the LSWPP is (or is to be) integrated. For instance, a study in [16] conducted an assessment of the grid-connected mode of operation for an offshore LSWPP. The study compared the cost margin when the power transmission from an offshore LSWPP is alternating current (AC) or direct current (DC). The study aimed to prove little significance in choosing DC over AC when transmitting power \begin{table}

However, it did not consider ensuring the LSWPP meets the grid code specifications before integration. This oversight underscores the crucial role of REGC in the operation of LSWPPs. A study of integrating a LSWPP into a weak distribution network was conducted in [17]. A 6 MW single WTGU that was sufficiently sized to approximate the acceptable megawatt capacity of a WPP was used in the study. Additionally modeled in this study was a 9 MW single WTGU for grid integration using the static synchronous compensator (STATCOM) [18]. The impact integration of wind power plants (WPPs) and wind turbine generator units (WTGUs) has on power system stability has been studied in the references [19; 20; 21]. None of these models were initially performed independently for grid compliance tests as required by the REGCs. Considering the models used in [17; 18; 19; 20; 21], it is understood that the computation of each component consumes time.
