Owing to generation and demand mismatch in a micro-grid, the frequency deviation and the rate of change of frequency (ROCOF) may become drastic at times. This is due to increased penetration of renewable energy sources that brings down the system inertia. Therefore, efficient control algorithms are required to mimic the inertial behavior of a conventional synchronous machine to arrest/limit the sudden...
In this paper, a D-STATCOM is used for improving the power factor at the load end. The degree of utilization of the power depends on the power factor of the loads connected to the network. Most of the loads in the distribution line, being inductive in nature, consume much of the reactive power. As a result, the power factor of the load deteriorates, leading to the limitation of the active power flow...
This project deals with the performance evaluation of an induction motor fed from a four-switch three-phase inverter. Here, instead of using six-switch three-phase inverter (SSTPI), a four-switch three-phase inverter (FSTPI) is used. This reduces the cost of the inverter, the switching losses, the complexity of the control algorithms and the interface circuits to generate six PWM logic signals. Both...
