Flexible control for small power generation employing renewable energy source used in isolated communities

The controllability of the electrical production is the main problem of renewable energy generators due to uncontrollable meteorological conditions. This study examines the feasibility for an isolated small power generation based on renewable energy source able to supplying different type of loads AC and DC with regulated voltage. The complete system is modelled in Matlab\Simulink with three closed loops under fluctuation of the source (variable prime mover of the generators) and sudden application of loads. Both the DC voltage and AC voltage are controlled to the desired reference. The present results show the effectiveness and validity of the proposed power generation system.
