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.
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.
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.
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 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.
Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control. According to Ref. , the shifting relationship between the energy reserve of energy storage and the kinetic energy of the rotor of a synchronous generator defines the virtual inertia of energy storage.
