#BOOST CONVERTER MATLAB SIMULINK PORTABLE#
Another advantage of using wind energy is the portable operation whenever wherever necessary. Thus it can be used to power rural areas where the availability of grids is very low. Wind energy can be a standalone generating unit or can be a grid connected generating unit depending on the availability of a grid nearby. Wind energy is abundantly available that has made it possible to harvest it and utilize it properly. The continuous use of fossil fuels has caused the fossil fuel deposit to be reduced and has drastically affected the environment depleting the biosphere and cumulatively adding to global warming. Renewable sources like wind energy and solar energy are the prime energy sources which are being utilized in this regard. Demand has increased for renewable sources of energy to be utilized along with conventional systems to meet the energy demand. One of the major concerns in the power sector is the day- to-day increasing power demand but the unavailability of enough resources to meet the power demand using the conventional energy sources. Keywords Wind energy conversion system(WECS), Maximum power point tracking (MPPT), Perturb and observe (P&O), Incremental conductance (INC). The simulated waveforms validate the system performance. The performance of the system is also evaluated for change in load.Ī PMSG based stand-alone WECS with boost converter is designed, simulated and modeled using the power system block set in MATLAB R2016a to obtain the results. For this three phase three wire systems is considered. The Voltage frequency controller receives/supplies active/reactive power and hence system voltage is maintained almost constant around it`s reference value. Therefore in order to reduce the change in system voltage and frequency to the smallest possible value, a voltage frequency controller is required. In addition to power optimization, variation in load as well as wind speed during variable speed operation, results drift in system voltage. Here simulation evaluation is done to know the working of MPPT and successfully optimize the generated power during a step change in wind speed. Among several methods, the most efficient method of MPPT technique is Perturbation and observation (P&O) which has its own virtues. Therefore in order to capture as much power as possible from wind during change in wind speed, maximum power point tracking controller is implemented. In variable speed operation, it is important that the generated power from PMSG should be optimized.

Select five values in these ranges for each scheduling variable and linearization obtained at all possible combinations of their values.Modeling and Simulation of the Wind Energy Electric Conversion System using MATLAB/Simulink You trim and linearize the model for several values of the scheduling parameters.įor this example, select a span of 10-60% for the duty cycle variation and a span of 4-15 ohms for the load variation. The scheduling parameters are the duty cycle d and resistive load R. To produce faster simulation and to help with voltage stabilizing controller design, you can linearize the model at various duty cycle and load values.įor this example, use the snapshot-based trimming and linearization. It shows nonlinear dependence on the duty cycle and the load variations. The average model is not a linear system. This variant typically executes faster than the Low Level Model variant. The BoostConverterExampleModel model implements such an average model of the circuit as its first variant, called AVG Voltage Model. These average models for the circuit are derived by analytical considerations based on averaging of power dynamics over certain time periods. Such behavior is studied at time scales several decades larger than the fundamental sample time of the circuit. In many applications, the average voltage delivered in response to a certain duty cycle profile is of interest. The model takes the duty cycle value as its only input and produces three outputs: inductor current, load current, and load voltage.ĭue to the high-frequency switching and short sample time, the model simulates slowly.
The Boost Converter block used in the model is a variant subsystem that implements two different versions of the converter dynamics. The circuit in the model is characterized by high-frequency switching.
