The increasing implementation of renewable energy sources (RES), along with the diversity of energy source types, has additionally imposed significant operational and management problems in distribution networks. These problems are manifested in voltage regulations, system stability and coordination of protection, both in the distribution and transmission networks. For the medium voltage (MV) network, this includes new energy sources and higher amounts of fault currents, invisibility of several faults in the existing protection scheme, reduction of the range of protection devices and reduction of the possibility of detecting small fault currents with existing protection relays. Such changes significantly reduce the possibility of proper distribution system protection, both in subordinate and superior networks. The subject of this paper is the presentation of a new concept of the use of automation in the management and arrangement of power system protection dependent on the scheme and configuration of an active MV network. The goals of this analysis and research are to find and define the necessary architecture in which the scheme and appearance of the MV network should be automatically detected, and based on network topology to establish new settings of protection devices (ground fault, overcurrent and short circuit protection). The contributions of generation units of RES in the MV network must be considered. This paper specifically analyses the problems of power system management with simultaneous harmonization of protection systems both in the transmission and in the radial distribution network, offering optimization algorithms that have the ability of achieving the optimal solution. The implementation of the proposed technique was tested on a radial connection integrated with a microgrid (MG) which has the possibility of two-way power supply. The obtained results indicate that the proposed technique can solve described problems in the coordination of protection system and network management, even with the dynamic character of operation mode of the networks.

“…Notwithstanding the improved security and tolerance of modern power systems towards temporary and permanent contingencies, the issues of stability and protection have been prevailing yet [1] [2]. The stability of a power system refers to the condition where it maintains the state of equilibrium for normal operation and retains its acceptable characteristics after being subjected to local or global disturbances.…”

Rising load demand and possibilities of short interruptions either due to temporary faults or equipment switching may lead to a transient instability in terms of growing oscillations and eventually result into cascaded outages if not being damped properly and timely. To damp out such oscillations, the power system stabilizers (PSS) are invariably being installed to regulate the excitation of synchronous generators. In this research, a comparative analysis among the two design variants of PSS i.e., Lead Lag and PID is performed by comparing the overshoot and settling time of generator active power after distrubance, to observe the effect of each on the system characteristics and nominal conditions. The results obtained show a better performance of PID based PSS having better overshoot response and reduced settling time for symmetrical as well as unsymmetrical faults.

“…The impact of DG and the type of the transformer connection have not considered for the different type of DG: Inverter-Based DG (IBDG) or Synchronous-Based DG (SBDG). Similarly, the approaches presented in the literature, as shown in Table 1, required communication between the relays, which will increase the cost and tripping time [12][13][14][15][16][17][18][19][20][21][22]. A limited number of research investigated the OCR and EF coordination problem together [4,20].…”

Nowadays, the Overcurrent (OC) and Earth Fault (EF) relays coordination problem is one of the most complex and challenging concerns of power protection and network operators due to the high and volatile generation capacity of renewable energy sources in the grid. In this article, a new and dynamic optimal coordination scheme based on a novel hybrid tripping characteristic has been designed and developed for Over Current Relays (OCRs). Considering the impact of renewable energy sources such as the photovoltaic (PV) system on fault characteristic, this work presents and verifies a novel dynamic and hybrid tripping to achieve minimum tripping time and improve the OCR and EF relays coordination performance in terms of security, sensitivity, and selectivity. The proposed dynamic and hybrid scheme will help the OCRs to cover the EF events, and it has been tested under different fault scenarios compared to the literature. The IEEE-9 and IEEE-33 bus systems are implemented in the ETAP package to validate the effectiveness of the proposed hybrid characteristics against traditionally well-established IEC characteristics. Furthermore, the performance of the proposed advance and dynamic protection approach which doesn't require a communication infrastructure is investigated for a power network with PV plants under different grid operation modes and topology to provide more robustness protection system. The results, as presented using Industrial software (ETAP), showed that the novel dynamic and hybrid tripping scheme improved the speed of the total time tripping different fault scenarios and location by more than 50% and covers all EF events compared to traditional OCR schemes from the literature. The proposed novel dynamic approach has superior performance in detecting high-impedance faults and significantly reducing the tripping time on the IEEE 33 bus network by 47%.INDEX TERMS Over current relays, Earth fault relay, Dynamic coordination scheme, Renewable energy sources, PV.
