techno economic potential of a renewable energy based microgrid system for a sustainable large scale residential community in beijing china
Renewable & Sustainable Energy Reviews, 2018Co-Authors: Shiyue Zhang, Yizhong Chen, Lixia RenAbstract:Abstract In this study, the techno-economic potential and optimal Configuration are investigated under various renewable energy (RE)-based, stand-alone and grid-connected microgrid scenarios. HOMER software is employed to assess the physical, operating, and economic performance of the system’s components, and to obtain the most cost-Effective Configuration pattern. The outputs obtained from the case study for a residential community in Beijing can help the decision maker identify the optimal adoption of renewable energy sources, electricity generation, and economic benefits. Results show that there is a very high potential for applying a predominantly RE-based microgrid in a residential community in Beijing, which could supply at least 90% of the onsite electricity demand with 47–100% RE sources. In the grid-connected model, the total net present cost (TNPC) of the microgrid system would be, at most, 57% of the obtained electricity less than that completely from the external grids. Results also indicate that it would be more cost-Effective when wind power becomes the main energy source and combined with moderately capacity of solar photovoltaic (PV) in the RE hybrid microgrid system. Additionally, a system with moderate size of batteries tends to be more ecologically friendly and cost-Effective both in the stand-alone and grid-connected models than a system without batteries.

Techno-economic analysis of a hybrid renewable energy system for an energy poor rural community
Journal of energy storage, 2019Co-Authors: Om Krishan, Sathans SuhagAbstract:Abstract Grid-independent hybrid renewable energy systems (HRESs), being eco-friendly and cost Effective, are turning out to be more Effective option for the rural areas where grid power availability is poor. This paper presents the techno-economic analysis and optimum design of a HRES, as proposed to meet out the residential and agricultural electric load requirements of an energy poor community of Yamunanagar district in the State of Haryana, India. Three different optimal Configurations, viz. wind/battery, PV/battery and wind/PV/battery are compared in respect of net present cost (NPC) and cost of energy (COE) to determine most economically viable option. For economic analysis and optimum sizing, all the necessary modelling and simulation is carried out using HOMER (Hybrid Optimization Model for Electric Renewable) software. From the simulation results, it is established that wind/PV/battery based HRES is the most cost-Effective Configuration for the specific location this investigation is about and also the optimum sizes of the different components are obtained. Further, for technical analysis, a MATLAB/Simulink model of the optimized system is built and its Effectiveness is demonstrated in terms of maintaining active power balance between the different components of HRES as well as keeping DC link voltage (VDC) and output AC voltage constant, irrespective of variations in solar irradiance, wind speed and connected load. The novelty of this work lies in using both HOMER and MATLAB simulation tools sequentially to carry out techno-economic analysis of the proposed HRES and validate the proposition.

Anisotropic damage coupled to plasticity: Modelling based on the Effective Configuration concept
International Journal for Numerical Methods in Engineering, 2002Co-Authors: Andreas Menzel, Magnus Ekh, Paul Steinmann, Kenneth RunessonAbstract:A model framework for anisotropic damage, that is kinetically coupled to inelastic deformations, is outlined. Key ingredients are the concept of the Effective undamaged Configuration and the assumption of energy equivalence. The pertinent rate equations for the chosen internal variables are integrated using the standard fully implicit scheme, and the Jacobian matrix of the resulting non-linear incremental constitutive problem is used to compute the algorithmic tangent stiffness in straightforward fashion. Numerical results showing the effect of deformation-induced anisotropy conclude the paper. Copyright © 2002 John Wiley & Sons, Ltd.
