Case study analysis of a new frequency response service designed for energy storage. Energy Storage Systems (ESS) are expected to play a significant role in regulating the frequency of future electric power systems.
. The value of energy storage systems (ESS) to provide fast frequency response has been more and more recognized. Although the development of energy storage technologies has made ESSs technically feasible to be integrated in larger scale with required performance
The Commission adopted in March 2023 a list of recommendations to ensure greater deployment of energy storage, accompanied by a staff working document, providing an outlook of the EU’s current regulatory, market, and financing framework for storage and identifies barriers, opportunities and best practices for its development and deployment.
. New frequency regulation services are emerging aiming to take full utilization of the ESS advantages. The major task of this paper is to review the existing grid connection requirements applicable to ESSs, as well as the emerg ng f quency response services demanding fast resp
Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
However, for storage to realize its full potential, a robust regulatory framework is needed. In the European Union (EU), the role energy storage plays in EU power markets will be formally recognized in the Electricity Market Design Directive (recast), which is expected to be adopted in Q1/Q2 2019.
