Sizing of a battery system based on simulation of operation in an islanded network

Abstract

The paper proposes a model and a methodology to size a battery system, which is aimed to operate in conjunction with a utility-scale PV plant for grid impact mitigation. The methodology covers the design choices that need to be made in the planning phase, when the detailed data and technical characteristics are not available. The model is based upon the requirements imposed by the transmission system operator and makes use of solar irradiance and grid frequency data. The studied time frame is an entire year, and it can be extended depending on the available data.
