Analysis of Large Scale Storage Impact on Distribution Network

Abstract

The installation of new smart grid technologies brings additional possibilities for power system operation. Among those technologies, energy storage promises to support energy transition towards a system with a high share of renewable energy sources. The paper outlines the results of the large-scale simulation in the distribution grid obtained within Horizon 2020 project STORY. Due to the characteristics of the modelled network, a stochastic Monte Carlo simulation approach is used for the network simulation with Matlab and OpenDSS software. The real-world database was tuned for Central European region and daily power flow simulations were performed for all four seasons. The impact of the storage was compared, based on the installed capacity in the network and in combination with different technology drivers. The results confirmed that the integration of battery storage devices has a considerable positive impact on the power system but there are still many challenges awaiting in the near future.
