“…The integration of distributed PV may change the duty cycles of the voltage regulators compared to the base case. Thus, a prorated cost of the in-line voltage regulators during the project's lifetime is estimated considering a price of 25,131 GBP 1 per phase of the regulator [52] and an additional maintenance cost of 5% of the total cost, i.e. 1,256.55 GBP [53].…”

Centralised, front-of-the-meter battery energy storage systems are an option to support and add flexibility to distribution networks with increasing distributed photovoltaic systems, which generate renewable energy locally and help decarbonise the power sector. However, the provision of specific services at distribution level remains under development for real applications in industry. To this end, this paper presents an exhaustive techno-economic analysis of the role of front-of-the-meter battery energy storage systems in primary distribution networks with presence of distributed PV covering: (i) the siting decision for storage systems using multi-objective genetic algorithm optimisation; (ii) the response when smart capabilities for PV inverters (e.g., volt-var control) are present; and (iii) the quantification of revenue streams and compensation schemes that would bring positive profitability when providing distributionspecific services based on the supply of real and reactive power. The performance of grid-level battery energy storage technology is evaluated in the IEEE 34-bus system particularised to the distribution code of Northern Ireland, UK. The techno-economic assessment covers one year of simulations at 1-minute resolution performed with the simulation tool EPRI OpenDSS and its Python communication interface. The results show that, besides the technical benefits of centralised battery storage systems, the economic compensation based on traditional transmission-level services is not sufficient for the profitability of these projects. Several ideas are explored to improve the profitability of these systems considering the local value and decarbonisation they add. The findings presented can direct system operators and regulators towards developing schemes to incentivise centralised battery energy storage projects in distribution networks in the context of distribution-level services.INDEX TERMS battery energy storage systems, distribution network services, distributed solar energy, flexibility services, photovoltaic power.

“…In combination with the existing hydropower (35 TWh) and other RES (especially wind), a 100% energy supply for Switzerland can be ensured by 2050, including replacement of nuclear power and fossil fuels (for mobility, heating). The growth of energy produced from RES, changes the nature of the world's power grids, shifting it from transmission level to medium voltage (MV) and low voltage (LV) levels [6]. The increasing distribution of power generation leads from presently unidirectional to a distributed and bi-directional power flow.…”

Electrifying the energy system with heat pumps and electric vehicles is a strategy of many countries to reduce CO2 emissions. Large electrification, however, poses several new challenges for the electricity system, particularly in combination with a simultaneous substitution of nuclear power plants by volatile renewables such as photovoltaics. The increasing consumption of electricity and the growing number of installed photovoltaic systems are pushing the existing electrical grid to its limits. Today's grid must be expanded with smart controllers and their components regulated. For this purpose, an understanding of the flexible participants such as boilers, heat pumps and electric vehicles, but also of the new production facilities such as photovoltaic systems must be built up. The aim of this work is to develop an energy model in which the change of these components can be simulated and analysed. To achieve this, data such as weather data, installed boiler capacities, installed photovoltaic capacities, heat pump data and installed vehicle charging stations were collected over the entire municipality. Afterwards, a load profile generator was created, which is supposed to generate a suitable profile over a day for different weather conditions, weekdays and holidays.
