Is the problem of parallel connected inverters in renewable energy system solved? Is it still active research area?
Can you please specify what kind of problems in parallel inverter you are looking for?
it will be easy to address the question.
I want to start PHD in control Engineering related to power electronics with renewable energy for islanded microgrid. so I am asking for the active research area in this part.
I would like to know more about what you mean by 'parallel' in this context. Do you mean that all the PV cells are parallel and fed to a number of separate inverters which are then paralleled to drive the grid? I am not optimistic about this approach - the control algorithms of the inverters might interact inappropriately, and the system would be wildly unstable. But you can parallel the output drive stages of an inverter and drive them using a single control system. Now the issue is the islanding. What will happen if the power supplied by the PV/inverters exceeds the power required by the islanded load? I think that you have a possible topic here, but please be very careful to specify just what it is that you are trying to do to - it would be a great shame if you get half way through then find you have a major inconsistency in your research design. But best wishes!
what i mean is mentioned in the attached paper. parallel inverters of multiple sources are connected to share same load and related problems. in this paper I felt that the researcher solved all the problems of this area and it is saturated. Is that true,? do I have a chance to add something?
