Özet

Battery energy storage systems (BESSs) are becoming increasingly prevalent in various aspects of our daily lives. Industrial applications, electronic devices, automotive sector, power drive systems of land, air and space vehicles and power grid applications are some of these areas. Effective integration of BESSs within power systems yields numerous benefits, both economically and from a technical constraints. In this study, various analysis have been performed to examine the effects of BESS integrated into the power system on the voltage, which is one of the technical constraints of the system. The capacity and maximum charge/discharge power of the integrated BESS is minimized with the Grey Wolf Optimization (GWO) algorithm to avoid unnecessary costs. These analysis were performed using MATLAB software on 34-bus standard test system. BESS was connected to the bus with the lowest voltage, as determined by the forward/backward load flow analysis method applied to the system, which considered the voltage levels across the power network. In addition, in establishing the times for charging and discharging the BESS, it was configured to store energy during periods of lower load demand and to supply power when voltage levels fall below specified minimum values. According to the obtained results, after the BESS was integrated into the 34 bus test system, improvements were observed in the voltage values of the test system. In particular, it was observed that the voltage value of bus 27, which has the lowest bus voltage, increased from 0.9423 p.u. 0.9501 p.u. at time 19.00 with the integration of the BESS. Consequently, the voltage limitations, which are crucial for the safety of the power system, are ensured by the minimum battery power and capacity incorporated into the system.
