This allows to distribute the inertia provision effort around the power system resulting in lower overall power and energy requirements for the energy storage. The validation is approached using the IEEE 9-bus system, then, the island of Santiago, Cape Verde is employed as a realistic study exploring its inertia needs.
Energy storage systems are recognised as the potential solution to alleviate the impacts of reduced inertia and intermittency in power systems due to the integration of renewable energy sources. Several energy storage technologies are available in the market with diverse power and energy characteristics, operational limitations, and costs.
The loss of the system inertia is an increasing concern in modern power systems due to the increasing integration of RES. The installation of energy storage or synchronous condensers are common practices aiming to enhance the stability. Different methods based on power curtailment of RES or ESS have demonstrated their feasibility for VI support.
An energy storage system (ESS) might be a viable solution for providing inertial response and primary frequency regulation. A methodology has been presented here for the sizing of the ESS in terms of required power and energy. It describes the contribution of the ESS to the grid, in terms of inertial constant and droop.
However, excessive cyclic load on the inertia-supplied energy storage systems can be detrimental to their lifetime through attrition; Further, issues such as round-trip efficiency and elevated individual costs remain technical and economic barriers for utility-scale applications.
