Benefits of battery energy storage system for system, market, and distribution network – case Helsinki

Defining and Evaluating Use Cases for Battery Energy Storage Investments: Case Study in Croatia

“…Network-level applications are considered in both transmission and distribution networks. BESS connected to the medium-level grid (10 kV) is investigated in [20] to test stacked battery applications, such as frequency control, control of reactive power and voltage, and peak shaving functionality, for the grid of Finland. The results show promising application in frequency control due to the BESS ability to provide a fast response and flexible modification of the control curves.…”

Smart City Resilience with Active Citizen Engagement in Helsinki

“…This system is described in the following section. Further examples of data-driven business practices under the Lighthouse umbrella are studies in autonomous, electrical busses (Rutanen & Åman 2019), battery energy storage (Hellman & Laasonen 2017), urban platforms and 3D city models (Ruohomäki et al 2018) and integration of heat pumps and solar thermal collectors (Rämä & Wahlroos 2018).…”

Energy storage management strategy in distribution networks utilised by photovoltaic resources

“…It is shown that the representative DG has less generation volatility compared to the total volatility of the DGs for the case where DGs separately participate in the market. On the other hand, the integration of EES units into distribution networks affects all the system profiles such as voltage profile, current profile and grid frequency, and any mismanagement in the operation of these units can threaten the network stability [7–9]. Sami et al .…”

“…[8] consider further the lifetime of the battery EES. Furthermore, besides voltage control, the frequency control due to the installed battery energy storage is studied in [9] where the results are obtained from the valuable experience of practical projects.…”
