This paper presents a comprehensive review and detailed investigation of the protection issues that may potentially arise due to the proliferation of technologies such as distributed generator (DG) and energy storage in future power distribution networks. A summary and critical evaluation of several potential protection and control solutions (applicable to the generators or the network), which are proposed as addressing one or more of the identified issues, are also presented. The analysis covers both economic and technological viability and feasibility. Finally, a mapping of the identified issues to the most appropriate proposed solutions is presented, along with discussion, analysis and conclusions. Index Terms-Future distribution network, distributed generators (DGs), protection issues and solution schemes.

“…Authors in a previous study presented a review on the techniques used for fault detection, classification, and location in distribution systems as well as transmission systems; importance is also given to the feature extraction methods on which the methods are implemented. Telukunta et al, surveyed fault location challenges associated with the distribution system under bulk penetration of RE sources. In this work, the protection issue associated with DG‐integrated distribution systems and microgrids is highlighted.…”

In the last decade, with increasing power supply from distributed generation (DG) to the distribution system, the traditional passive radial distribution systems transformed into an active multisource system. The nature of fault location schemes designed for the distribution system has traditionally been based on unidirectional power flow assumptions, making them ineffective for a distribution system with a higher level of DG penetration. New grid regulations require DGs to remain connected to the system in the event of a fault to provide support to the grid and improve system reliability. This makes the fault location process important as the timely location of a fault speeds up the restoration process, which improves the system reliability. Herein, providing a comprehensive review of the available techniques for fault location in the distribution system with DG penetration is focused on. An analysis is given on the shortcomings of traditional protection methods when applied to DG‐integrated distribution systems. A comparative analysis is carried out in which the merit and demerit of each technique is assessed. A discussion on some other important technical issues arising due to DG integration, such as effects on the stability of the distribution system, is also given.

“…Increased capacity of sources changes the modes and processes in electric power systems (EPS), especially the level of short‐circuit currents (SCC) . This raises the need to solve a number of important and complex tasks . The reliability and efficiency of the tasks solution depend on the adequacy of SCC calculations, especially their maximum values—peak SCC.…”

Summary Reliability and efficiency of electric power systems (EPS) operation depend on the adequacy of information about quasi‐state and transient processes in EPS used for their research, design, and operation. A value of short‐circuit currents (SCC), especially their maximum values, is one of the important information used for different tasks. The difficulty of obtaining this information is the need to use a large‐scale EPS mathematical model for SCC calculation. The total mathematical model of any large‐scale EPS is a stiff and nonlinear system of differential equations of high order. Such system cannot be solved analytically. Satisfactory solution is also impossible by using the numerical approach that leads to the need for applying simplifications and limitations reducing the adequacy of simulation results. Therefore, each solution should be validated. The comparison of simulation results with the field data is the most reliable way of validation. However, the acceptable amount of field data cannot be obtained in the foreseeable future in view of the obvious variety of EPS modes, especially emergency ones. An alternative way of validation is suggested in the paper: the using of an adequate reference model instead of field data. The experimental sample of hybrid real‐time power system simulator having the necessary properties and capabilities is used as the reference model. The indicated possibility of SCC calculation validation is proved by the experimental studies shown in the paper.
