Abstract

Due to the dispersion and randomness of photovoltaic (PV) power generation, the photovoltaic output power is fluctuant. As the increasing penetration of photovoltaic system, it plays an important role for the stability of power system. In this paper, photovoltaic is combined with the battery to form a photovoltaic-battery system. And a novel control strategy is proposed to restrain the photovoltaic power fluctuations and suppress the low frequency oscillations of power system. The energy storage device of the photovoltaic-battery system is composed of a battery and a BUCK/BOOST converter. The PV array and energy storage device connect to the DC side of the grid-connected inverter in parallel. The control strategy of the BUCK/BOOST converter is composed of voltage loop and current loop, which can make the PV array work at the maximum power point and decide to charge or discharge the battery. And the control strategy of the grid-connected inverter is composed of speed loop, power loop and current loop, which can make the grid-connected inverter output active power and reactive power according to power references. Simulations are carried out with MATLAB/SIMULINK. And the practicability of the proposed control strategy is verified in simulations.
