doi:10.3969/j.issn.1000-7229.2019.09.005

Abstract

Abstract: As an excellent flexible resource， energy storage equipment plays an important role in multiple scenarios of system operation. In current grid-side storage planning research， there is a lack of assessment methods for the energy storage demand boundary under multiple application scenarios. On the basis of the operation history data and power system operation simulation method， this paper presents a storage demand assessment method for multiple scenarios. This paper applies the method to calculate the storage capacity demand under three scenarios： frequency regulation， peak regulation and smoothing renewable energy output for Jiangsu Power Grid. Among them， the demand for frequency regulation is 289.3 MW/134.2 MWh； the demand for smoothing renewable energy output is 389.6 MW/629.2 MWh and 636.8 MW/433.5 MWh； and the demand for peak regulation is 1 245 MW/1 680 MWh. Suggestions for the choice of storage types are also given.

Key words: energy storage, frequency regulation, peak regulation, smoothing renewable energy output, demand assessment
