This paper analyzes the effect of introducing an energy storage (ES) system in an
intermittent renewable energy power plant such as a photovoltaic (PV) installation.
The aim of this integration is to achieve an improvement in the operability of these
power plants by increasing their production predictability. This will allow a further PV
integration within the electrical power system, facilitating the system’s load–demand
balance. In this manner, the paper proposes two power management strategies (PMSs),
each with different configurations, for operating a PV power plant: the first focuses on
fixing constant power production and the latter focuses on reducing the high frequency
fluctuations of the production. Thereafter, this paper analyzes and quantifies the ratings
of the ES system (ESS) required to ensure a reliable performance of the plant on an
annual basis for each of the PMSs with their different possible configurations. The
resulting ES ratings vary with these PMS configurations. It can be concluded that
significant improvements in production predictability are achieved with an ESS energy
capacity of approximately 50% of the average daily energy produced by the PV panels
and a power rating of around 55% of the plant’s rated power. All the results are based
on 1-year-long simulations which used real irradiance data sampled every 2min. [-]
