Coordinated operation of multiple inverter based renewable distributed generators as an active power injector and reactive power compensator

摘要

Integration of Renewable Energy like Wind and Solar has started paving ways for a green environment with the introduction of Schemes like Feed in Tariff Program. Particularly North Europe, Germany, Spain, USA, Canada, China, and India have shown a strong achievement in expanding the wind energy systems. This has given a new dimension in the area of research pertaining to Power Electronics applications in Power Systems. This paper presents the effects of coordination between Static Synchronous Compensator (STATCOM) and a Wind Farm Integrated into a Power System Network. A suitable test system is chosen for performing the analysis in order to characterize the performance of the entire power systems. The intent is to examine the efficacy of the STATCOM in providing the support during the Low Voltage Ride Through condition when a Wind Farm is integrated and aiding the Voltage Dips. Apart from this, the response of a STATCOM during a fault conditions are also analyzed. Further, a review of Sub synchronous Resonance in a Wind Farm using STATCOM is discussed. In addition to that, a theoretical description of PV interfaced with the same Voltage Source Inverter/STATCOM providing coordinated operations of Wind Farm are also discussed. The manifestation of the idea is carried out using MATLAB Simulink Software.
