“…In order to solve this problem, this study investigated a large number of research materials, including the grid generation technology based on the earth subdivision theory. GeoSOT, the global subdivision grid in Beidou Grid, is called Geographical coordinate global subdivision based on One dimension integer and Two to n-th power to realize the construction of power grid data space [23]. The specific implementation principle is shown in Figure 1.…”

“…In this way, the transformation relationship between the coordinates of the grid spatiotemporal data and the longitude and latitude of the grid location corner is established. When defining the locating corner, the setting is based on the area where the grid is located [24][25]. When the height of the grid spatiotemporal data is zero, the constructed model is the grid of the grid coverage surface, that is, two-dimensional grid.…”

In the process of unified data processing, due to the lack of analysis of its spatio-temporal attributes, the fitting effect of the data corresponding to the same household is poor. Therefore, a unified method for spatio-temporal data of power grid based on Beidou grid code is proposed. After the sphere corresponding to the coverage area of the grid is divided proportionally, the mutual conversion relationship between the coordinates of the grid spatiotemporal data and the longitude and latitude of the grid positioning corner is established, and the ontology grid spatiotemporal data in the grid grid module is divided into different classes. In the data unification stage, based on the control points (spatiotemporal data of the target power grid), the nonlinear interpolation method is used to realize the unification of multivariate data, and the spatiotemporal data set of the target power grid is interpolated to obtain the coverage surface of the power grid data, so as to realize the data unification on the basis of elastic interpolation. In the test results, the unified data fitting statistical parameters and Ljung Box Q (18) parameters under the design method are at a high level, with good fitting effect.

Each country must determine the Grid Code conditions and apply these criteria to integrate distributed generation (DG) systems into the existing electricity grid and to ensure a stable power system. Thus, experimental studies are required to provide an effective, national, and specific Grid Code. In this study, the Turkish Grid Code’s electrical criteria were examined, and the application of these criteria was carried out on a developed PV-based DG. A real-time energy management system (RTEMS) was proposed in the study. Electrical parameters on the developed DG were monitored in real-time by considering IEEE 1547, IEEE 929–2000, and Turkey’s electrical criteria. A practical grid code study was firstly investigated in detail about the Turkish Grid Code by a developed real-time monitoring-control and protection system. The proposed RTEMS method in the study is implemented as an inverter-resident system; thus, it provides advantages over many energy management systems embedded in the inverter. The degradation in power quality and non-detection zone (NDZ) problems encountered in active and passive island mode detection methods developed embedded in the inverter are eliminated in the proposed method. With the RTEMS method, where under and over-voltage, under and over voltage frequency, and unintentional island mode events can be detected in real-time, both the existing grid-code requirements are met, and the existing power quality and NDZ problem is eliminated with the recommended inverter-independent RTEMS method.

“…Recently, electricity subventions in Egypt have waned gradually, which has encouraged the consumers to own PV systems. Incorporating large PV amounts is not an easy mission due to several economic and technical constraints [7]- [9]. Therefore, the grid protection infrastructure and the system's compatibility should be guaranteed.…”
