Assessment of energy storage systems as a reserve provider in stochastic network constrained unit commitment

Abstract

Recently, the provision of the reserve from energy storage systems (ESSs) is introduced as a source for ancillary services to address the uncertainties of renewable power generations. The performance of ESSs is analysed while they are applied as a provider of regulation reserves. It has been revealed that previous stochastic models neglect the impact of corrective dispatches, related to the provision of regulation reserves, on the energy level stored in the ESSs, which can lead to large deviations. This study coordinates the stored energy of ESSs to be feasible regarding the dispatches in the base schedule and rescheduling within scenarios. Also, the wind speed fluctuations are considered as the source of uncertainty, and scenarios of wind energy are generated using the Weibull distribution function. The IEEE 24-Bus standard test system is applied for the examination of the proposed model. The results show that the proposed model can manage the performance of ESSs in rescheduling within scenarios, while the coordinated reserve provision of ESSs can remove the concerns about insufficient stored energy of ESSs.

Robust frequency constrained uc using data driven logistic regression for island power systems

“…A robust formulation is employed in this paper to include the uncertainties of RES. To ensure the provision of sufficient and fast reserves, different solutions are introduced in the literature ( [5][6][7][8]). While new sources of the reserve are being introduced, it's also essential to make sure that the quality of frequency transitions is guaranteed in the scheduling process, in case of any abrupt contingency.…”

“…Papers [4][5][6] of this Special Issue are in this category. Paper [4] by M. Habibi, et al, proposes the usage of energy storage in order to mitigate the uncertainties imposed by the usage of renewable energy sources. Key to this is the observation that previous stochastic models may result in large deviations due to the fact that they do not take into account corrective dispatches.…”

A privacy‐preserving approach to day‐ahead TSO‐DSO coordinated stochastic scheduling for energy and reserve

“…Although the T&D interference more frequently appears in balancing and congestion management, involving DSOs in day‐ahead scheduling will reduce the need for ancillary services in real‐time operation [33]. The UC problem is usually applied for day‐ahead scheduling of energy and reserves [34]. Reference [35] calculates LMPs of distribution networks in a centralized UC problem for T&D networks.…”
