in a more generic and more appropriate way for the direct application in research activities and in engineering projects. This article presents the method proposed by Beluco et al.

A still open question is the relationship between how to idealize raw data and the effects of complementarity to be explored. For example, a hydro PV hybrid system can be studied from data idealized by average energy availabilities, but also by maximum values and minimum values, leading to different technical and economic performance results.

This concept of 'performance limit' can be improved to the concept of 'idealized performance', which would be a hybrid system performance in response to a given series of idealized data. This method deals with an idea of performance limit that could be associated with an idealization of raw data that would be difficult to reach in real conditions. The idea is to extract variability and intermittent effects from renewable resources and work with smooth mathematical functions. 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. presents a fairly complete survey of the articles related to complementarity published in the last years and brings a definitive discussion about the concept of energetic complementarity.
Years later, the work of Risso et al explored the concept of complementarity between renewable energy resources located in different locations and proposed a method to evaluate spatial complementarity. discussed the concept of complementarity and proposed a method to evaluate temporal complementarity.
Knowing better the effects of complementarity on the performance of hybrid systems then becomes necessary. Possible complementarity between energy resources may contribute to better project viability, but the characteristic variability of renewable resources makes it difficult to assess the effects of complementarity on the performance and reliability of hybrid systems based on complementary resources. Predicting renewable energy availability is difficult because of its typical variability, and planning its technical and economic feasibility becomes a daunting task.
Utilizing idealized energy availability, the result sets a performance limit. The method allows to evaluate the influence of different levels of complementarity between the exploited resources on the cost of energy and capacity shortage. This article presents a method for analyzing the performance of hybrid systems based on complementary resources. This performance limit can be established with an idealization of the mathematical functions describing the energy availability of the explored renewable resources. 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. Renewable resources may have intermittent characteristics that make the study of the influence of complementarity on the performance of hybrid systems quite difficult. The complementarity between energy resources can influence the performance of hybrid generation and storage systems, and can also decisively influence their design.
