Abstract

Because of the attributes of solar irradiance and PV panels, batteries are generally used in photo voltaic power systems to reduce the power variations. Due to this attributes, the power management and control algorithms are necessary to maintain the power flows in hybrid micro grid system. Control algorithms for the system must be able to stable the voltages of the buses and to manage power flows. So the paper suggesting a PMS (The power management system) for hybrid micro grid system with DC and AC buses, for the islanded and grid connected cases. The suggested PMS is effective in stable the frequency and control the DC and AC bus voltages flexibly, monitoring the voltages and powers of each circuit and dynamically matching the system power flows in different working conditions independently of the disturbances induced by operational modes of coupling, radiation and temperature variations and load adjustments.
