Line loss reduction and voltage profile improvement in radial distribution networks using battery energy storage system

Fossil fuels are known as the main energy source in the world. Factors such as increasing power demand, shortage of fossil fuel resources, and shortage of production capacity in industrialized countries, greenhouse gas emissions and climate change faced with problems in power production. Efficient use of energy storage systems such as batteries is considered as an adequate solution to avoid the above problems. In addition, the energy storage provides many advantages such as stability in unstable or unbalanced production load, improve voltage profile, improve power quality, economic benefits and improve the reliability of power system. In this article, effectively on losses, voltage profile, and network load is controlled using energy storage units (Batteries) and development of Optimal Power Flow (OPF). The proposed method is implemented on a typical radial distribution network using software Digsilent® Power Factory. The test result is provided.
