Wind technology is one of the fastest developing renewable technologies. Squirrel cage induction generator (SCIG) with back to back fully rated converter used for wind energy conversion systems (WECS) is a meritorious option among its class. SCIG's offer advantages of being robust, suitable for any harsh environment, cheaply available and unsophisticated than the other types available. To enable increased...
The existing Ancillary Services (AS) in the Electric Reliability Council of Texas (ERCOT), Texas Independent System Operator (ISO), were developed in the late 1990s based on inherent characteristics of conventional synchronous generation in the grid. ERCOT system and its generation mix have undergone significant changes over the past two decades. Therefore ERCOT staff and stakeholders are currently...
A Marx generator delivers high power electrical pulse in very short duration and can be configured to be compact. This ultrafast coaxial Marx generator has also been developed without pulse shaping/peaking circuit. The results of 5-stage ultrafast coaxial Marx generator has a rise time of 800ps, maximum output voltage 75kv, pulse width(FWHM) of 1.5ns, and source impedance 63Ω is presented. The coaxial...
This paper deals with the implementation of a controller for an isolated wind energy conversion system (WECS) using an isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The reference source currents are computed using the power balance theory to control the voltage and frequency of WECS. Three-leg voltage source converter (VSC) with a battery energy storage system (BESS) is...
This paper deals with investigation on the performance of voltage and frequency controller (VFC) of a wind power generation using a capacitor excited isolated asynchronous generator (IAG) feeding dynamic loads. The amplitude of load currents is estimated using the low pass filter to control the voltage and frequency of IAG system. Three-leg voltage source converter (VSC) with a battery energy storage...
