“…According to previous research on protection of BESS in a DC microgrid, fault on the bus at BESS side and fault on DC terminals at battery side are the two fault locations as identified in [12]. Based on the project model in this research, similar fault locations have been determined in a block diagram as shown in Fig.…”

This research paper presents the power protection study on a grid-connected Battery Energy Storage System (BESS) in a typical Malaysia low-voltage (LV) residential network. The BESS model and control algorithm is developed in MATLAB/Simulink environment. The BESS model can charge and discharge its energy with an algorithm-controlled bidirectional AC/DC converter. The paper also presents two cases for BESS short circuit evaluation to investigate stability of internal and external systems of BESS. The protection level on BESS is also optimized by introducing a time-delay characteristics model to coordinate circuit breakers in compliance with standards outlined in IEEE Std 1375-1998, IEC/EN 60898-2, IEC/EN 60947-2, UL 1077, and CSA 22.2. No.235. The paper presents BESS system stability with and without overcurrent protection. As a conclusion, BESS was interrupted within stipulated time. In case of internal short circuit protection failure, a backup protection will act on isolating BESS from the grid provided

“…The second issue is the rate of current rising [10], [11]. Regarding the two issues, the power electronic switches used with BESS may also be harmed by the current and its increasing rate [12]. The sudden decline in battery state of charge (SOC), which had an adverse effect on battery lifetime, is the final issue [13].…”

Installations of an Energy Storage System (ESS) with various functions such as power stabilization of renewable energy, demand management, and frequency adjustment are increasing. In particular, ESS for demand management is being established for high-voltage customers (300 KVA–1000 KVA) who have placed an Auto Section Switch (ASS) at the connection point within the distribution system. However, a power outage may occur in the Power Receiving System (PRS) when a short-circuit fault due to insulation breakdown occurs at the ESS DC side. The reason for this breakdown is that the fault current is reduced by transformer impedance, and the ASS is opened before the DC power fuse. Therefore, using the Graphic Solution Method (GSM), this paper presents an operation algorithm for protection coordination that isolates the fault section by first operating the DC power fuse with a small fault current. Furthermore, fault analysis modeling for a PRS composed of a switchgear section, a main distribution panel, a Power Conditioning System (PCS), a power fuse, and a battery is performed through PSCAD/EMTDC. From the simulation results, it is confirmed that the fault section is quickly isolated, and power outages for high-voltage customers are prevented because the DC power fuse selected by the proposed operation algorithm of protection coordination is opened before the ASS.
