“…As reported in [39], synthetic inertia is obtained by applying a control law proportional to the frequency derivative (RoCoF). Some applications of this control are reported in [40], [41]. However, a control law that follows continuously the RoCoF trajectory can lead to a rise in the frequency response settling time, because of the inertial support given after having reached the nadir point.…”

Small-sized non-synchronous islands, which are inherently characterized by low system inertia, will face in the next years the challenge of integrating larger and larger amount of renewable energy sources, leading to further reduction of inertia. Several means to support inertia and frequency transients have been proposed in the literature, including energy storage systems, distributed generation, and demand response. LED street lighting systems are widespread control resources, which in a smart grid scenario, can be regulated by means of local or remote control signals. This article investigates the possibility to regulate the power consumption of LED street lighting to provide frequency support in a system characterized by reduced total inertia. Tests are carried out integrating the simulation of the non-synchronous power system of an Italian small island with the response of an actual LED street lamp, in a Power Hardware-in-the-Loop testing environment. Both synthetic inertia and fast frequency response approaches are tested and discussed.

“…Several works have shown the advantages of regulating frequency through distributed energy resources, as demand response [1] or storage systems [2]- [7], adopting advanced control schemes such as synthetic inertia (SI) [2], [3], [5] or fast frequency response (FFR) [4], [5]. In [8], the authors using a single controller to provide a mixed contribution of SI and FFR, associating different weights to the proportional contributions to RoCoF and to frequency deviation.…”

Providing fast frequency regulation by means of energy storage systems is currently considered as a viable solution to low-inertia issues, caused by power electronics-interfaced generators. In particular, hybrid energy storage systems, composed by more energy storage technologies having different power and energy ratings, can optimally support the frequency regulation. A supercapacitor/battery storage system, for example, can exploit the supercapacitor dynamic active power response for synthetic inertia control, while the battery can provide primary and secondary frequency regulation. However, the optimal energy management of hybrid energy storage systems during transients needs to be addressed further in literature. In this paper, a State of Charge (SOC) feedback control scheme is proposed, that adjusts the active power output reference depending on the state of charge, avoiding excessive stress on the components and limiting the state of charge excursions. Control system parameters are optimally tuned minimizing a weighted multi-objective function in the solution of an optimal control problem. Test results adopting different weights are presented and discussed.
