“…A straightforward way of providing this ancillary service is by implementing a power versus frequency droop curve in the BESS controller in such a way that active power is injected or absorbed when the frequency decreases or decreases, respectively [152,153]. To reduce the cycling of the battery, it is usual to incorporate a dead band around the fundamental frequency [154]. In addition, this ancillary service can be at least partly provided by renewable generation units, which usually operate maximizing the power conversion from the primary energy source [155].…”

In the last decade, distribution systems are experiencing a drastic transformation with the advent of new technologies. In fact, distribution networks are no longer passive systems, considering the current integration rates of new agents such as distributed generation, electrical vehicles and energy storage, which are greatly influencing the way these systems are operated. In addition, the intrinsic DC nature of these components, interfaced to the AC system through power electronics converters, is unlocking the possibility for new distribution topologies based on AC/DC networks. This paper analyzes the evolution of AC distribution systems, the advantages of AC/DC hybrid arrangements and the active role that the new distributed agents may play in the upcoming decarbonized paradigm by providing different ancillary services.

“…For a three-bladed wind turbine, the wind shear and tower shadow can lead to 3p and the higher, such as 6p, 9p, 12p, etc, equivalent wind speed oscillations, [15][16][17][18] where p indicates the rotational frequency of wind turbine. The equivalent wind speed oscillations of wind turbine are produced by turbulence, wind shear and tower shadow.…”

The rotational speed of MW class variable speed wind turbine is 5 to 25 revolutions per minute generally, 19,20 so the 3p is in 0.25 to 1.25 Hz.…”

Summary Flickers of wind farm should be assessed accurately since they become a limiting factor for integrating wind turbines into grid. Furthermore, since cyclical low‐frequency oscillation powers (CLFOPs) caused by wind turbines will lead to low‐frequency oscillation in the power system, CLFOP monitor and mitigation is wanted. A novel digital time‐frequency domain implementation of flickermeter using analytical mode decomposition (AMD) is proposed in this paper. The results of simulation and actual measurement show the proposed flickermeter can (1) meet design standard requirements of IEC 61000‐4‐15; (2) obtain the more accurate CLFOP monitor in time‐frequency domain compared with wavelet packet decomposition (WPD) and empirical mode decomposition (EMD); and (3) realize the CLFOP mitigation for reducing the probability of low‐frequency oscillation in power system through sending the power limitation instruction to the energy management system (EMS) of wind farm.

The design and implementation of the battery energy storage system in DC micro-grid systems is demonstrated in this paper. The battery energy storage system (BESS) is an important part of a DC micro-grid because renewable energy generation sources are fluctuating. The BESS can provide energy while the renewable energy is absent in the DC micro-grid. The circuit topology of the proposed BESS will be introduced. The design of the voltage controller and the current controller for the battery charger/discharger are also illustrated. Finally, experimental results are provided to validate the performance of the BESS.
