Abstract

Photovoltaic power generation has the characteristics of intermittency and randomness, and its output power has strong volatility, which will endanger the stable operation of the power grid when connected to the grid. Using energy storage can reduce the volatility of photovoltaic grid connected power and realize the stabilization of the fluctuation of photovoltaic grid connected power. This paper analyses the requirements of the grid connected power fluctuation rate of the coupling energy storage device of the photovoltaic power generation system and uses the variation modal decomposition to decompose the original photovoltaic power to obtain the grid connected power that meets the fluctuation requirements. An over calculation example verifies that the photovoltaic power can reduce the power fluctuation after being compensated by the hybrid energy storage system and compares and analyses the configuration results of different energy storage schemes, verifying that the method proposed in this paper can reduce the power of energy storage capacity and annual comprehensive cost to improve the economy of the system.
