Özet

In the recent years, microgrids have become increasingly popular among the consumers due to its energy efficient mechanism, network benefits and improved energy reliability. However, when they are operated as autonomous systems, several technical problems related with its operations and control has emerged as a challenge. To overcome this impending issue, this paper proposes an optimized approach by implementing adaptive solar PV generators with MPPT control (maximum power point tracking) to support an islanded microgrid in a low voltage network. Due to improper control and high maintenance, the PV generator provides very low efficiency during conversion. Therefore, the proposed strategy offers an effective coordination between inverter V-f control (voltage and frequency) and P-Q control, MPPT control and energy storage control of the islanded microgrids to remove device fluctuations and deviations. Also, the control strategy employed take care of State of Charge (SOC) stabilization of battery unit. The simulation of the proposed model is carried out in Matlab/Simulink. The results clearly confirm the potency of suggested controlling and adaptive strategy.
