Abstract
The paper presents the importance of the grid inertia constant for the frequency stability of the future high-res low-inertia power systems. Since more and more renewable energy sources (RES) are being connected to the power system via inverters, the grid inertia constant is reduced. This issue can be mitigated by applying appropriate control mechanisms through which RES can provide virtual inertia and provide rotating reserves for primary frequency control. The concept of a virtual inertia provision using battery energy storage system (BESS) is elaborated in the paper. By applying a virtual inertia concept, RES can provide support for frequency control during disturbances almost like conventional synchronous generators. The influence of virtual inertia on the stability of the part of Croatian power system was analyzed using BESSwith a control mechanism that enables its participation in frequency control.
