A new voltage regulation strategy using developed power sharing techniques for solar photovoltaic generation-based microgrids

Integration of solar photovoltaic (PV) sources to power grid is increasing rapidly in recent years. Since the PV source is an intermittent source, this causes many challenges to distribution network. To overcome these challenges, a voltage regulation strategy using a developed power management technique for microgrid system is proposed. The technique is based on voltage ride through capability. The active and reactive power flow along with the voltage profile has been deeply investigated to improve the stability of the distribution network. As a testing environment, three microgrid configurations developed in MATLAB/Simulink have been investigated. The study shows a faster response time and lower circulating current in configuration 2. Moreover, it revealed the effectiveness of the power management technique when a cluster of dispatchable and non-dispatchable distributed generators is in operation
