The modern power system and future ones include several intelligent devices. It also integrates renewable energy sources, energy storage, energy microgrid control system, hybrid networks, and smart grids with the wide application of information technology and communication. The most crucial goal in the smart grid application is improving safety reliability within the network. Recent studies have recommended the development of smart grid technology that enhances the reliability of electric power systems increases efficiency and improves the detection of faults for protection; this will reduce the duration of interruption of the number of customers affected by the outages. Moreover, smart grid technology decreases the power loss of energy usage and improves the efficiency of the system. And protection is one of the most important challenges facing smart grid deployment. In this chapter, protection for smart grids using differential relays is presented. The differential scheme is a very reliable method of ensuring the safety of protected areas. This chapter discusses the differential relay parameters with various fault conditions. Therefore, the protection scheme affirms the rapid separation of the fault zone to reduce damage to the equipment. The simulation results show that the method is effective and reliable.

“…Many publications are devoted to the evaluation of the performance of distance relay applied for protection of a line compensated by FACTS devices. In [8,9], the impacts of UPFC on distance relays are discussed and an adaptive protection scheme based on phase component approach and an adaptive protection scheme using artificial neural network are proposed, respectively. In [10], it is demonstrated that static VAR compensator (SVC) and static synchronous compensator (STATCOM) cause mal-operation of the distance relay in calculating the impedance, faulty-phase detection and also delays in operation.…”

Unified power flow controller (UPFC) has impact on the performance of distance relay during power swing. Generally, power system's parameters oscillate during power swing and since UPFC operation depends on some of these parameters (bus voltage, active and reactive power), the UPFC injects oscillated series voltage and draws oscillated shunt current. These oscillating series voltage and shunt current influence distance relays, as the impedance seen by a distance relay during power swing changes in UPFC-compensated lines. This study shows how and why series voltage and shunt current change during power swing. Moreover, the admittance swing characteristic is proposed in this study and effects of series and shunt branches of UPFC on the admittance seen by a distance relay during power swing have been examined. 2 Power swing admittance characteristic Nowadays, most distance relays monitor the apparent impedance and make decision based on this parameter. However, our reason for utilisation of admittance in UPFC-compensated line is only to simplify the analysis. The admittance plot is more convenient in UPFC-compensated line because it is possible to separate and so analyses the impact of series and shunt part of UPFC on admittance trajectory.
