“…These results are similar to those reported in [15] with an acceptable accuracy. The optimal objective value in [18] has been reported as 10.9499 seconds, while [19] reported different optimal objective functions as 8.8423 seconds and 8.5112 seconds using PSO-TVAC-1 and PSO-TVAC-2, respectively. The obtained optimal relay settings are similar to those reported in [15] by considering the same short-circuit currents and the objective function value is 8.427 seconds.…”

This paper investigates the coordination problem of overcurrent relays (OCRs) in presence of wind power generation and electrical energy storage (EES) systems. As the injected short-circuit current of inverter-based devices connected to the electrical grid is a function of the power electronic withstand capacity, the short-circuit level would be limited for these types of devices. Furthermore, since the short-circuit current is a function of the pre-fault current, it is highly needed to take different conditions into account to accurately evaluate the injected current by such devices. This would mainly matter for the EES system operating in either charging or discharging modes, as well. This paper evaluates different operation strategies considering the variations of the load demand and the presence of large-scale wind farms as well as an EES system, while validating the suggested method for coordinating the directional OCRs (DOCRs).

“…Sehingga koordinasi relay tersebut menentukan kontinyuitas suplai listrik serta saidisaifi [5]. Oleh karena itu perlu dilakukan setting koordinasi yang tepat antara OCR yang terpasang di penyulang (feeder) dengan OCR yang terpasang di incoming gardu induk agar didapat kerja relai yang selektif, peka dan handal [6,7].…”

Dibutuhkan pola koordinasi antar OCR agar diperoleh sistem pengamanan yang handal dalam mengamankan transformator dari gangguan arus lebih. Pola koordinasi yang digunakan di Gardu Induk 150 kV Rawalo saat ini adalah pola koordinasi kaskade, namun kelemahan pada pola ini adalah pengaturan waktu kerja OCR incoming selama 1 detik, sehingga jika terjadi kegagalan kerja pada OCR feeder maka transformator akan terganggu selama 1 detik. Oleh karena itu, dibutuhkan pola koordinasi baru yang tidak mengabaikan selektifitas sistem pengamanan dan dapat mempercepat waktu kerja OCR incoming yaitu pola koordinasi non-kaskade. Studi ini dilakukan untuk menganalisa penerapan pola koordinasi OCR non-kaskade di Gardu Induk 150 kV Rawalo. Untuk mengetahui kinerja pola koordinasi non-kaskade dilakukan simulasi pada Matlab Simulink 7.0.1. Hasil simulasi kinerja pola non-kaskade jika OCR feeder mengalami kegagalan kerja maka OCR incoming akan bekerja 0,6 detik setelah gangguan terjadi, sehingga transformator hanya akan terganggu selama 0,6 detik.

“…In order to solve the optimal coordination problem of DOCR, Mancer and colleagues have developed a PSO-time varying acceleration coefficient algorithm that takes the optimum pickup current as a discrete parameter and the TMS as a continuous parameter. The computation results with the proposed method are compared with the calculations made with MATLAB-GA, classical PSO and other techniques, and the algorithm has been shown to improve the solution of the problem [34]. Modified PSO algorithm is also presented to eliminate problems such as determining the starting point of the relay coordination, rescanning the entire system in each iteration and based on the possibility of changing particle positions in each update in the classical PSO algorithm [35].…”

Power system protection is one of the main element of modern energy management concept. The main task of these systems is to deactivate the faulty element or network part as soon as possible. The protection relays, called intelligent electronic devices, also have different functions than these basic functions. However, overcurrent, distance and differential protection are still used as the three basic components. In this study, current studies on these relays for coordination of the protection system have been analyzed. The research topic is limited to the main functions of the relays. Further study will examine the tasks that these relays have in providing data to the energy management system. It can also focus on the concept of wide area protection, event recording and modern communication protocols.
