This paper deals with the characteristics of a Boost Converter in the presence of uncertain load parameters. An Interval System analysis is adopted to evaluate the interval extension of load parameters and then a PID controller is designed using Particle Swarm Optimization(PSO). The PID-PSO controller meets the requirement of robust design and the design(More)
This article represents the reactive power compensation issue with the help of FACTS controller and transient stability analysis in a Wind-Diesel hybrid power system. DFIG is widely used due to its simplicity and high efficiency in wind energy generation system. Back to back converters are employed in DFIG based Wind Energy Conversion System (WECS) with(More)
This paper presents a study of improvement in stability in a single machine connected to infinite bus (SMIB) power system by using static compensator (STATCOM). The gains of Proportional-Integral-Derivative (PID) controller in STATCOM are being optimized by heuristic technique based on Particle swarm optimization (PSO). Further, Bacterial Foraging(More)
This paper discusses reactive power regulation and stability study in an isolated wind type microgrid. This paper proposes a STATCOM controller for compensating reactive energy in a wind-diesel based stand-alone hybrid power system. The transfer function small signal model of the stand-alone hybrid power system has been considered which consists of a photo(More)
This paper presents an anti-islanding protection scheme for a grid tied inverter. In this scheme, the oscillation variation in frequency is estimated by Estimation of Signal Parameters via Rotational Invariant Technique (ESPRIT). The proposed system is implemented in MATLAB and real time in OPAL-RT. Series of simulation results demonstrate that(More)
