In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
The hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
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 ].
Battery Energy Storage Station Frequency Regulation Strategy The large-scale energy storage power station is composed of thousands of single batteries in series and parallel, and the power distribution of each battery pack is the key to the coordinated control of the entire station.
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.
Aiming at the problems of low climbing rate and slow frequency response of thermal power units, this paper proposes a method and idea of using large-scale energy storage battery to respond to the frequency change of grid system and constructs a control strategy and scheme for energy storage to coordinate thermal power frequency regulation.
