Provision of Frequency Containment Reserve from Lithium-Ion Batteries in a Low Inertia Grid

The increased share of renewable energy results in reduced inertia in power systems. Furthermore, fast variations in renewable sources, such as solar and wind, create an imbalance between generation and demand, which could result in frequency stability problems. Ancillary services, such as frequency control, are needed to stabilise the grid. Storage batteries have emerged as a solution to provide ancillary services to the grid. Lithium-ion (Li-Ion) batteries are among the best chemical batteries that could provide ancillary services. An accurate simulation model is crucial for investigating the viability and dynamics of Li-Ion batteries when integrated into the power system. This paper presents a PowerFactory modelling approach to examine the viability of lithium-ion batteries for providing ancillary services in a low-inertia grid. The paper mainly focuses on delivering frequency containment reserves using Li-Ion batteries. The simulation results show that Li-Ion batteries can provide ancillary services under low inertia conditions.
