Abstract
The complementarity between energy resources can influence the performance of hybrid generation and storage systems, and can also decisively influence their design. Renewable resources may have intermittent characteristics that make the study of the influence of complementarity on the performance of hybrid systems quite difficult. The establishment of a performance limit of hybrid systems based on renewable resources and the study of the effects of complementarity considering this limit can provide interesting results. This performance limit can be established with an idealization of the mathematical functions describing the energy availability of the explored renewable resources. This article presents a method for analyzing the performance of hybrid systems based on complementary resources. The method allows to evaluate the influence of different levels of complementarity between the exploited resources on the cost of energy and capacity shortage. Utilizing idealized energy availability, the result sets a performance limit.•A method to evaluate the impact of complementarity on the performance and reliability of hybrid systems.•The energy availabilities of the renewable sources are idealized and allow the characterization of a limit of performance.•Different levels of complementarity can be related with design parameters of hybrid energy and storage systems.

Summary
Predicting renewable energy availability is difficult because of its typical variability, and planning its technical and economic feasibility becomes a daunting task. The paper by Beluco et al [1] proposes a method allowing access to the effect of complementarity on a hybrid system using an idealized energy availability function instead of natural raw data. A hydro PV hybrid system can be studied from data idealized by average energy availabilities, and by maximum values and minimum values, leading to different technical and economic performance results.
