A Modified Droop Control Method for PV Systems in Island Mode DC Microgrid
TLDR
The integrated MPPT algorithm with droop control algorithm based on modified P&O algorithm operates the system not only in power sharing mode but also in MPPT mode to obtain the maximum power.Abstract:
Ensuring a proportional power sharing algorithm for parallel connected sources in a microgrid system makes them more efficient and prevents their overloading. For this purpose, the droop control technique is one of the widely used methods. However, this technique is generally insufficient to obtain maximum power from intermittent sources such as photovoltaic (PV) systems and wind turbines. Therefore, this paper presents the integration of MPPT algorithm with droop control algorithm of a PV system. Thus, the droop control method based on modified P&O algorithm operates the system not only in power sharing mode but also in MPPT mode to obtain the maximum power. The developed algorithm is compared with conventional droop control methods and satisfying results are obtained.read more
