In this paper, the integration and control of energy storage systems such as supercapacitor into a distribution system STATCOM (D-STATCOM) with voltage controller is developed to enhance power quality and improve distribution system reliability. This paper develops the control concepts to charge/discharge the supercapacitor by the D-STATCOM, and validates the performance for an integrated D-STATCOM/supercapacitor system for improving distribution system performance. The potential performance improvements are verified by simulation results for rapidly varying arc-furnace loads for voltage flicker mitigation, by supplying fluctuating real power by the D-STATCOM/supercapacitor system.}, journal={2008 IEEE POWER ELECTRONICS SPECIALISTS CONFERENCE, VOLS 1-10}, author={Parkhideh, Babak and Bhattacharya, Subhashish and Han, Chong}, year={2008}, pages={2242-+} }

However, with wind being an uncontrollable resource and the nature of distributed wind induction generators, integrating a large-scale wind-farm into a power system poses challenges, particularly in a weak power system. In the paper, the impact of STATCOM to facilitate the integration of a large wind farm into a weak power system is studied. First, an actual weak power system with two nearby large wind farms is introduced. Based on the field SCADA data analysis, the power quality issues are highlighted and a centralized STATCOM is proposed to solve them, particularly the short-term (seconds to minutes) voltage fluctuations. Second, a model of the system, wind farm and STATCOM for steady-state and dynamic impact study is presented, and the model is validated by comparing with the actual field data. Using simulated PV and QV curves, voltage control and stability issues are analyzed, and the size and location of STATCOM are assessed. Finally, a STATCOM control strategy for voltage fluctuation suppression is presented and dynamic simulations verify the performance of proposed STATCOM and its control strategy}, number={1}, journal={IEEE TRANSACTIONS ON ENERGY CONVERSION}, author={Han, Chong and Huang, Alex Q. and Baran, Mesut E. and Bhattacharya, Subliashish and Litzenberger, Wayne and Anderson, Loren and Johnson, Anders L. and Edris, Abdel-Aty}, year={2008}, month={Mar}, pages={226–233} }

For a 40 MVA EAF at Tennessee, USA, a cascade-multilevel converter (CMC) based STATCOM with high bandwidth is proposed for EAF flicker mitigation. In this paper, flicker mitigation techniques by using a CMC-based STATCOM are presented and verified through a transient network analyzer (TNA) system. The required STATCOM capacity is first studied through a generalized steady-state analysis. Secondly, the STATCOM control strategy for flicker mitigation is introduced and simulation results are given. Finally, a TNA system of the STATCOM and EAF system are designed and implemented. Experimental results from the TNA test show that the proposed CMC-based STATCOM and its controller can efficiently and rapidly mitigate the EAF flicker.}, number={2}, journal={IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS}, author={Han, Chong and Yang, Zhanoning and Chen, Bin and Huang, Alex Q. and Zhang, Bin and Ingram, Michael R. and Edris, Abdel-Aty}, year={2007}, pages={378–385} }
