6 FAQs about Frequency Modulation Energy Storage Device
Which energy storage system is used in secondary frequency modulation control strategy research?
The previous energy storage systems involved in secondary frequency modulation control strategy research mostly used the energy storage system as a small-capacity traditional frequency modulation unit for power signal distribution.
How do energy storage systems control secondary frequency regulation?
When the Energy Storage System (ESS) participates in the secondary frequency regulation, the traditional control strategy generally adopts the simplified first-order inertia model, and the power allocated to each energy storage unit follows the principle of equal distribution.
How to control ESS wind power based on primary frequency modulation?
In, a control strategy of ESS wind power participating in primary frequency modulation of the power system has been given by using PCS to improve the ESS capacity reserve, then to maximize economic benefits, and effectively reduce the impact of large-scale wind power connected to the grid on frequency.
What is the structure of the power system frequency adjustment system?
When the ESS is participating in the secondary frequency regulation of the power system, the structure of the power system frequency adjustment system is shown in Fig. 1. The dispatching center divides the AGC signals to a different department. The thermal power unit is assigned Pg and each ESS unit is assigned PEi.
Can the ESS system satisfy the frequency requirements of the power system?
In China, the requirement of frequency deviation in power systems is not more than ±0.2 Hz for large-scale regional power grids and ±0.5 Hz for small-scale power system. Therefore, the ESS system can satisfy the frequency requirements of the power system under the control strategy of this paper.
How does simulation speed affect the calculation accuracy of secondary frequency modulation?
Since we use a large-scale ESS to participate in the secondary frequency modulation of the power system, the balance between simulation speed and calculation accuracy needs to be considered in the design of the control strategy process, and the calculation speed is affected by the model polarity response and the SOC estimation part.
