  • a developed voltage control strategy for unbalanced distribution system during wind speed gusts using smes
    Energy Procedia, 2016
    Co-Authors: Emad A Mohamed, Hossam S Salama, Sayed M Said, Mamdouh Abdelakher, Yaser Qudaih
    Abstract:

    Abstract The fast response, high efficiency and long lifetime of superconducting magnetic Energy Storage (SMES) compared to other Energy Storage systems make it a preferable selection for Energy Storage Solution for wind power generation. SMES has attracted many researchers to study its potential applications in power systems. This paper discusses a scheme of fuzzy logic controlled SMES to minimize the voltage fluctuations of three-phase unbalanced radial distribution systems connected to wind Energy conversion system (WECS) with large scale penetration level of 30% during wind speed gusts. In this paper, wind turbine used is of squirrel cage induction generator (SCIG) with shunt connected capacitor bank for power factor improvement. SMES unit consists of superconducting coil, DC-DC chopper, step down transformer, power conditioning system, and cryostat/vacuum vessel. The control technique is based on fuzzy logic controller (FLC). The studied system is 33-bus three-phase unbalanced radial distribution system. The SMES and WECS were connected to weakest buses in the system, namely Buses18 and 33. The control strategy is discussed in details and the proposed system is evaluated by simulation in MATLAB/SIMULINK package. The simulation results demonstrate the performance of the proposed fuzzy-logic-controlled SMES in mitigating the voltage fluctuations under wind speed gusts.

  • thermodynamic analysis of a novel hybrid thermochemical compressed air Energy Storage system powered by wind solar and or off peak electricity
    Energy Conversion and Management, 2019
    Co-Authors: Cheng Zhou, Elham Doroodchi, Behdad Moghtaderi
    Abstract:

    Abstract In this paper, a hybrid Energy Storage system based on integrated thermochemical and compressed air Energy Storage is proposed. This hybrid system can store Energy from wind, solar and/or off-peak electricity simultaneously. In the Energy charging process, the concentrated solar heat is used to provide heat for the endothermal reduction of tricobalt tetroxide to cobalt monoxide. Meanwhile, wind Energy is employed to drive a series of compressors for compressing the input ambient air. The products (cobalt monoxide and compressed air) are then stored temporarily. In the Energy discharging process, the compressed air is released to oxidize cobalt monoxide which generates high-quality heat. The superheated and pressurized air is then used for electricity generation via air turbines. In conventional compressed air Energy Storage, natural gas is employed for superheating the compressed air. By contrast, the proposed hybrid system completely eliminates the use of fossil fuel and replaces it with the exothermal oxidation heat of cobalt monoxide, which originates from solar Energy. Moreover, cobalt oxides can be stored at ambient temperature for an extended period without any insulation requirements, which renders the system to be a long-term Energy Storage Solution. According to the thermodynamic analysis, the hybrid system can achieve a round trip efficiency of 56.4% with an Energy Storage density of 3.9 kWh/m3. Meanwhile, the proposed system has an overall exergy efficiency of 75.6% with the largest exergy destruction process taking place in the intercoolers. The sensitivity analysis demonstrates that the round trip efficiency is mostly sensitive to the reactivity of cobalt monoxide, the isentropic efficiency of compressors and turbines, and cavern operating pressures.
