For research work- "power control strategy of PV, FC" which system can be more feasible? Also which software other than homer is free available for design which is valid worldwide?
about the software, for power system simulation I think GridLAB-D is good. To install it you need assistance from youtube.
it depends on your application or your purpose of work if it is in rural area it is better to use stand alone system.
I would recommend you read this:
FEASIBILITY AND SIMULATION OF A SOLAR PHOTOVOLTAIC INSTALLATION IN DC FOR STANDALONE SERVICES BUILDINGS,
But I think the standalone systems are feasible in both as in rural and non-rural areas. And taking into account the control perspective the standalone is easier to control than the grid connected undoubtedly. I strongly suggest read the following paper:
Analysis and assessment of an off-grid services building through the usage of a DC photovoltaic microgrid.
Kind regards!
Grid connected is much complex.
In grid connected system you need to make protection coordination and anti-islanding protection for several situations when power of PV >Pload , PV
I am very much satisfied with Srete N. sir- grid connected is more complex than off-grid system. If we look for some valuable real time case study and its validation from simulation, than off-grid finds a variety of research gap which may be implemented to solve various problems.
Grid connected is more feasible, because you can sell the excess power in the grid instead of dumping it.
It depends on your application or your purpose of work if it is in rural area it is better to use stand alone system. Agreed
Grid connected is more complex, you can switch to grid connected later. You can begin with stand alone
We start by choosing the system (connected or isolated) according to the needs and the site. Then we choose a control strategy according to the variables to control
