Standalone generation schemes based on local renewable energy sources have great potential to replace diesel-generators supplying remote communities. However, consumer loads and renewable energy sources are variable in nature and require power management to maintain supply quality. This paper presents scheme for voltage-frequency regulation in standalone wind generation under variations in un/balanced...
Present investigation deals with the comparison of performance of a Generalized Impedance Controller (GIC) based 3-phase self excited induction generator (SEIG) terminal voltage and frequency regulator, having single and two-loop control, in an isolated wind/microhydro type renewable energy conversion system (RECS). Where, GIC is a PWM voltage source converter with dc-bus battery, having controlled...
Single control loop based two schemes for regulation of voltage and frequency of Self Excited Induction Generator (SEIG) based stand-alone 3-phase 4-wire renewable energy conversion system (RECS), under perturbations in speed and balanced/unbalanced load are presented. For the regulation, a Generalized Impedance Controller (GIC), a PWM voltage source converter having battery storage at its dc bus,...
In this paper, single control loop based scheme for regulation of voltage and frequency of Self Excited Induction Generator (SEIG) based stand-alone 3-phase 4-wire renewable energy conversion system under source and balanced/unbalanced load perturbations is presented. The regulation is accomplished by maintaining reactive and active power balance across individual phases of SEIG using a Generalized...
Poor voltage and frequency regulation under source and load perturbations limit the use of self excited induction generator (SEIG) in isolated and dispersed generation, which can exploit wind/microhydro type renewable energy sources. In the present work, a Generalized Impedance Controller (GIC), which is a pulse-width-modulated voltage-source-inverter with a dc-link battery, is used to regulate both,...
