Smart storage solution for wind systems

Abstract

Energy storage devices and solutions are required for power quality and balance within wind systems. In the context of rapidly expanding of distributed energy sources, the wind energy converters are in the center of interest. In this case, the direct dependence of the power generation capability for a given wind speed represents a major problem of wind energy conversion with regard to large-scale network integration. This paper proposes an overall solution which consists of a wind plant with a smart Storage Modular System (SSMS) where the wind source -as stochastic one-is coupled over a dc bus with two storage modules and a smart grid interface. The investigated system consists of three modules: a) the stochastic module (variable wind turbine with PMSG and ac/dc + bust converters), b) the short term storage module (flywheel with power electronic converter) and c) the medium/long term module (Vanadium Redox Flow Battery with power electronic converter). All of three modules are interfaced with the network and insulated loads by a grid interface module (power electronic converter, filter and transformer). To the related SSMS, are accomplished computer simulations. In order to validate them, laboratory tests are also presented.

Smart electrical energy storage system for small power wind turbines

“…To control the IM, a DTC control scheme has been considered and implemented in the laboratory, as presented in [6], [7], [8], [9], [10]. The DTC is used to control the IM, because the authors estimated a meaning of 50% decrease in calculus time of DSPs comparable with the vector control method.…”

“…Based on the Matlab/Simulink implemented model, the characteristics during the operating mode of the system wind generator-flywheel are made in the absence of the reactive power and are presented in [10].…”

Reliability Evaluation of Renewable Energy-Based Power System Containing Energy Storage

“…Since the wind speed and also the solar radiation continuously change and are not accurately predictable, the output powers of these renewable resources are variable. To overcome this challenge and for reducing the intermittency of the output power of these resources, energy storages such as batteries [1][2][3][4][5][6][7][8], pumped storage [9], a system containing water electrolyze, hydrogen tank and fuel cell [10][11][12][13][14][15], ultra-capacitor [16], superconducting magnetic energy storage [17], compressed air energy storage [18] and flywheel [19] can be used in connection with these power plants. Amongst these storages, flow batteries such as vanadium redox type are made in large capacities and can be used in large-scale power system [8].…”

“…In this paper an analytical approach for reliability evaluation of renewable-energy based power system containing battery storage is suggested. For reliability evaluation of power system containing renewable resources and energy storages many efforts have been done, but more of these works are related to the reliability evaluation of the renewable energy-based power system containing battery storage in the isolated, hybrid or distributed generation systems [1][2][3][4][5][6][7]. Besides in these papers, Monte Carlo simulation method is used for load, wind and solar generation modelling.…”

Application of a hybrid energy storage in a remote area power supply system

“…The power mismatch resulting from the above scenarios creates unexpected voltage and frequency excursions which may cause severe damages to customer equipments [1]- [2]. The integration of Energy Storage Systems (ESS) to such a self generating standalone power system provides improved system performance including frequency stability, extraction of maximum energy from renewable sources, load balancing and improved power quality [3]- [4].…”
