Free QuoteThe use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
However, the use of combined battery - flywheel storage systems is only minimally investigated in literature in terms of energy benefits and, above all, effects on battery life are missed. In Ref. [ 23] a feasibility study is carried out concerning the coupling of a flywheel with a battery storage system for an off-grid installation.
A typical flywheel energy storage system, which includes a flywheel/rotor, an electric machine, bearings, and power electronics. Fig. 3. The Beacon Power Flywheel, which includes a composite rotor and an electric machine, is designed for frequency regulation.
The surplus energy is stored both in battery and flywheel. The amount of energy stored by the battery is equal to QB (or less if restated according to energy and power charging constraints), while the flywheel absorbs the fluctuations to provide an almost constant charging profile to the battery. Case 2.1b with battery fully charged.
While many papers compare different ESS technologies, only a few research, studies design and control flywheel-based hybrid energy storage systems. Recently, Zhang et al. present a hybrid energy storage system based on compressed air energy storage and FESS.
In this context, the present study deals with the analysis of a combined flywheel-battery system for residential storage applications. In the proposed architecture, the storage and usage of the energy is mainly provided by the battery pack while the flywheel has peak shaving and peak satisfaction function.
