“…Nonetheless, the participation in primary frequency regulation also entails an important advantage -the actual activated power is on average significantly lower than the contracted capacity. Based on recent studies about FCR activation in Belgium, on average the capacity use stays below 10% of the reserved power during 90% of the time [65]. This activation factor is highly dependent on the frequency variations within the considered region, but under any circumstances below the contracted power capacity.…”

“…According to (15), when a customer does not have EESS, the PV output power of that customer has to be limited to the sum of the local consumption and mop P . The stored energy in EESSs can be used to increase the self-consumption, trade power in the electricity markets, charge EVs, and participate in the primary frequency control [39]- [42]. To have a more cost-efficient operation, combination of different services can be considered [43]- [45].…”

Photovoltaic (PV) systems are among the renewable sources that electrical energy systems are adopting with increasing frequency. The majority of already-installed PV systems are decentralized units that are usually connected to lowvoltage (LV) distribution grids. The PV hosting capacity of an LV grid is usually limited by overvoltage, and the efficient control of distributed electrical energy storage systems (EESSs) can considerably increase this capacity. In this paper, a new control approach based on the voltage sensitivity analysis is proposed to prevent overvoltage and increase the PV hosting capacity of LV grids by determining dynamic set points for EESS management. The method has the effectiveness of central control methods and can effectively decrease the energy storage required for overvoltage prevention, yet it eliminates the need for a broadband and fast communication. The net power injected into the grid and the amount of reactive power absorbed by PV inverters are estimated using the PV generation forecast and load consumption forecast, and the dynamic operating points for energy storage management are determined for a specific period of time by solving a linear optimization problem. Simulations performed on a realistic LV feeder of the Danish island Bornholm verify the performance of the proposed method.

“…This approach allows the usage of a battery storage with a smaller storage capacity without violating the requirements for FCR provision. Since the battery investment is the largest part of the investment costs [8][9][10], this combination with a PtH module can be economically beneficial [11].…”

Batteries provide growing amounts of Frequency Containment Reserve (FCR) in the German electricity market. We examine the ideal battery capacity as well as the optimal state of charge (SoC) setpoint for provision of FCR following a profit maximization approach. While a lot of research neglects taxes, their huge influence on the results is considered. In addition to stand-alone battery systems, we also consider hybrid systems, combining a battery storage with a Powerto-Heat (PtH) module. The hybrid system has two variants: In one variant energy is sold when the battery is fully charged, while in the other one the PtH module is used. Based on historical frequency and market data for one year, the performance of the different system variants is evaluated via a simulation. 2048 different combinations of battery capacity and SoC setpoint are examined. The performance of each configuration is evaluated with the net present value (NPV) method, allowing an economic comparison. The results show a financial advantage for the hybrid systems which sell energy when the battery is fully charged. The system configuration with the best NPV is a hybrid system with a battery capacity of 480 kWh and an SoC setpoint of 98 %. The optimal battery capacity of all considered variants has a lower capacity to power ratio than the usual ratio of 1 MWh to 1 MW, assumed in most other studies. Nonoptimal battery capacities have a stronger negative effect on the economic efficiency of the systems than non-optimal SoC setpoints. The results emphasise that the battery capacity is a critical investment decision.
