This paper critically evaluates a number of uncertainty importance measures for use in power system stability studies. Sensitivity analysis of uncertain system parameters is vital as new technologies proliferate and the total level of system uncertainty grows. Accurate assessment of the importance of different uncertainties can guide power system operators towards parameters which will require the greatest levels of mitigation or increased monitoring in order to reduce the uncertainty and its subsequent impact. Local and global sensitivity analysis techniques are described and evaluated within this paper, including non-parametric methods, variance-based approaches, and distribution-based techniques. The techniques are illustrated using a large 295-bus realistic network model of a generic distribution system. Numerical experiments on dynamic models are used in order to assess the impact of uncertainties on the mitigation of system frequency excursions using single-site and distributed energy storage devices.

“…Therefore, the key parameters associated with the generator and governor model are subject to a degree of uncertainty. 1) Energy Storage Devices: Energy storage devices can be used in order to support the system frequency during excursions by quickly injecting active power to cover the temporary generation shortfall [33], [34]. A simple proportional controller with a storage system time constant is used in this study shown in Fig.…”

“…A simple proportional controller with a storage system time constant is used in this study shown in Fig. 3(b) which simply injects power when the local monitored frequency deviates from its reference value [34], [35]. This injection of power can only occur if there is sufficient energy stored within the device and the state of charge (SOC) does not fall to zero.…”

“…Thus, energy storage systems (ESSs) are considered as a promising technology to provide FR service for ensuring stability by balancing the power generation and load demand [3][4][5]. The integration of energy storage device with RES to reduce the fluctuation of grid frequency has been widely conducted [4][5][6][7][8][9][10][11][12][13]. The various types of ESS technology have been researched for FR such as battery ESSs (BESSs) [4,5,11,12], SCs [13], superconducting magnetic energy storage (SMES) [10], and flywheels [9].…”

The paper proposes a coordinated operation method of two independent storages for managing state-of-charge (SOC) and for providing ancillary service concerning frequency regulation (FR); furthermore, this article also introduces the power allocation scheme between two storages in consideration of the coverage of the frequency band for each storage along with the SOC management scheme of the supercapacitor and battery. We also provide a guideline for the storage sizing on the basis of the smoothing time constant. Additionally, we verify the advantage of the HESS in extending the lifetime of the battery, which is estimated by a real-time state-of-health (SOH) calculation method. The Bode plot of the proposed method is analyzed to observe the power spectrum coverage in the frequency domain through the case studies using PSCAD/EMTDC and MATLAB.
