Abstract

Abstract: For the current use of energy storage in the PV output smoothing, this paper introduces a geometric weighted moving average filtering algorithm to obtain the reference value of the energy output battery in the PV system so as to reduce the impact of PV power on the power grid. By improving the moving average filtering algorithm, the proposed algorithm not only improves the delay of the filter, but also has the ability of adaptive stabilization. On the basis of energy storage output reference value, a new method of modifying the reference value by fuzzy control is proposed, which maintains the state of charge (SOC) of the energy storage battery in a reasonable range to ensure that the energy storage battery has the best running condition and the minimum capacity configuration.

Key words: photovoltaic grid-connection, power smoothing, energy storage system, geometric weighted moving average filter, fuzzy control
