GA Based Controller for Autonomous Wind-DG Micro grid
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 1
Abstract
A single renewable source of energy when integrated with other sources of energy it is termed as hybrid system. In this paper an active power control strategy has been developed such that when the wind alone is not able to meet the energy demand, without compromising the frequency a transition occurs to wind diesel mode so that the energy demand is met. This work proposes the coordination of WDG(Wind DG), VSC’s are used for two purposes one is frequency control and another is voltage control. PMBLDC generator is used as a wind power generator and the Incremental conductance method is used as MPPT along with boost converter. This output is stored into battery system (BS) and surplus is supplied to the consumer loads. Back propagation feed forward (BPFF) control scheme is used for VF control of VSC. This controller provides harmonics elimination, load leveling and reactive power compensation and also regulates the voltage at PCC. Genetic algorithm is used for the purpose of tuning PI controller of BPFF. The performance and the analysis is done in a user friendly MATLAB/Simulink environment.
