عنوان انگليسي : Coordinated V-f and P-Q Control of Solar Photovoltaic Generators With MPPT and Battery  Storage in Microgrids

Abstract

The microgrid concept allows small distributed energy resources (DERs) to act in a coordinated manner to provide  a necessary amount of active power and ancillary service when required. This paper proposes an approach of coordinated and integrated con trol of solar PV generators with the maximum power point tracking (MPPT) control and battery storage control to provid voltage and frequency (V-f) support to an islanded microgrid. Also, acti ve and nonactive/reactive power (P-Q) control with solar PV, MPPT and battery storage is proposed for the grid connected mode. The control strategies show effective coordination between invert er V-f (or P-Q) control, MPPT control, and energy storage charging and discharging control. The paper also shows an effective coordination among participating microresources while conside ring the case of changing irradiance and battery state of charge (SOC) constraint. The simulation studies are carried out with the  IEEE 13-bus feeder test system in grid connected and islanded micr  ogrid modes. The results clearly verify the effectiveness of proposed control methods. The simulations are carried out in Matlab and Simpowersystems.
