Grid-connected Energy Storage System (ESS) can provide various ancillary services to electrical networks for its smooth functioning and helps in the evolution of the smart grid. The main limitation of the wide implementation of ESS in the power system is the high cost, low life, low energy density, etc.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
. 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
To compensate for the mismatch of generation-load, an advanced energy storage system is proposed in the paper so that the nominal frequency of the power system is maintained. The fast ramping merit of the energy storage system is a feat to give regulation of the frequency.
As a new type of flexible regulatory resource with a bidirectional regulation function [ 3, 4 ], energy storage (ES) has attracted more attention in participation in automatic generation control (AGC). It also has become essential to the future frequency regulation auxiliary service market [ 5 ].
The frequency regulation can also be achieved in the wind energy system by using the battery storage [ 5] and the battery energy storage can be optimized for controlling the frequency [ 6 ]. The statcom integration with energy storage can give better results [ 7] and this can be achieved in the power system [ 8, 9 ].
