In a different approach, a dual-feedback damping strategy was proposed in and , where output power and angular frequency were fed back through a first-order inertia link to correct power deviation. However, this method increased system order and introduced numerous parameters, complicating the overall design.
A dual-battery ESS control strategy that can avoid the discharge depth and frequent charge/discharge is proposed in . However, the above strategies ignore the variation of BESS output demand due to the time-varying characteristics of wind power, especially during short-term strong power fluctuations.
The dual-layer control works cooperatively to avoid over-charge/over-discharge, which helps extend the lifetime of BESS. In order to compare the accuracy and effectiveness of different control strategies, the energy-optimized rate index, the cycle lifetime index and the SOC discretization index are proposed respectively.
It proposes a damping strategy based on bidirectional proportional adjustment, which ensures that the grid-forming energy storage system can respond quickly and stably to changes in active power reference and grid frequency. Furthermore, the research findings and contributions of this paper are summarized as follows:
This paper proposes a dual-layer control strategy that can achieve fluctuation smoothing of the wind power, as shown in Fig. 3. In the first layer control, the parameter T of FLF is adaptively adjusted by the wind power fluctuation rate. It could dynamically optimize the power command for BESS.
However, the BESS units may face the problem of over-charge/over-discharge if the power dispatch strategy for multiple units of BESS is improper, which results in lifetime degradation. In this paper, a dual-layer cooperative control strategy of multiple BESS units is proposed.
