Reactive Power (VAR) Compensation using Photovoltaic (PV) Inverter

Project description

NOTE: if the writer needs any information or reference, please contact me on my e-mail or phone number as follow:

the most important thing now is to have the MATLAB/SIMULINIK for the proposed assignment below. I do require a couple of words to be done by the write. However, if I like the writer’s thinking and style of writing, I will cooperate with him for the whole project and make a thesis together. I need the simulation to be done BEFORE the 2nd of MAY, and just few pages on the whole project. he can then proceed later and provide me with the final input a week after.<br

The project objective is attached.<br /><br />

and the reference thesis where the “ IDEA “ only has been adopted from is also attached.<br /><br />

<br /><br />

my main objective is develop further and further for what the referenced paper has suggested.<br /><br />

<br /><br />

this project concerns doing simulation by using “ MATLAB/SIMULINK “ and need to be detailed.<br /><br />

<br /><br />

I just need the project simulation “ not a dissertation or thesis “ with some explanation about the implementation in software with few words for my understanding. so I can write the thesis myself as I am facing a problem in implementing this module.<br /><br />

<br /><br />

Please have a look and let me know the soonest.<br /><br />

<br /><br />

It should not take time as I only lack the use of Matlab. just the implementation itself and to treat it as a coursework. I need this to be completed before 2nd of April if possible.<br /><br />

<br /><br />

Thanks.<br /><br />

BACKGRAOUND<br /><br />

<br /><br />

While PV systems integration into the grid will be growing, the effective utilization of PV inverters will remain low. On average, most of today‘s grid-tie PV inverters operate an average of 8-10 hours per day. In order to increase the utilization of grid-tie PV inverters, they can be operated in reactive power compensation mode when PV power is unavailable [1]. While injecting reactive power into the grid can be easily realized by applying the appropriate phase shift between current reference and grid voltage, the task gets more complex when PV power is not available since the inverter needs to draw power from the grid, regulate the DC bus, and inject the desired level of reactive power. In [25], the authors provide a detailed analysis of PV inverters‘ operation in a VAR compensation mode when active power is not available. A new control scheme was proposed that enables the inverter to absorb little active power from the grid, regulate its DC bus voltage within limits, and inject the desired level of reactive power [1]. More research can be conducted in this area to improve the proposed VAR compensation system.<br /><br />

PROJECT OBJECTIVE<br /><br />

<br /><br />

The main objective of this project is to investigate the utilization of Solar PV system inverters for network VAR compensation. Need to implement it using a software (MATLAB/SIMULINK) or any suitable software and practice the way that inverters feed the grid using reactive power compensation. <br /><br />

<br /><br />

RESEARCH APPROACH<br /><br />

<br /><br />

The tasks that the student should consider in this research project are as follows:<br /><br />

1. Literature review of existing techniques used for controlling both grid-connected single- and three-phase PV inverters and also review of existing VAR compensation techniques. <br /><br />

2. Develop a new algorithm for controlling PV inverters that can also operate as VAR compensators during the unavailability of solar energy (e.g. at night).<br /><br />

3. Simulate and validate the proposed algorithm on a case-study. <br /><br />

4. Implement the proposed VAR compensation method in the lab and validate it with experiments. <br /><br />

5. Write the thesis. <br /><br />
