In this paper a distributed control strategy for coordinating multiple battery energy storage systems to support frequency regulation in power systems with high penetration of renewable generation is proposed.
Conclusion A distributed control scheme is developed for coordinating distributed BESS in DNs to provide real-time voltage regulation and satisfy the required voltage profiles specified by TSOs. An optimisation problem is formulated to schedule the operation of the BESS inverters for an efficient and real-time delivery of voltage support.
As illustrated in Sanz et al. (2018), the current practice to control energy storage devices, including BESS, is to use a droop-based controller. However, this decentralised approach fails to regulate the voltage to the desired setpoint since it is basically a proportional controller.
Authors in Liu et al. (2017) propose a distributed approach that coordinates DERs to regulate voltage profiles, whilst in Tang et al. (2018) a distributed approach to the accelerated voltage regulation, which requires the same R / X ratio, is developed.
Most of the objective functions used in distributed voltage regulation problems, including the one defined in the Problem 2.2, can easily satisfy these assumptions, e.g., network loss minimisation ( Li et al., 2019 ), and voltage control ( Zeraati et al., 2016, Zhu and Liu, 2015 ).
It can be seen that both the benchmark case of no voltage control and the decentralised approach are not able to regulate the voltages at all nodes of the DN within acceptable ranges, especially during periods of high PV power generation, as shown in Fig. 7 and Fig. 8.
