“…When the objective is to reduce the longest event of consecutive drought days, the optimal PV share is lower, but in any case larger than the wind share. These results can be compared to other studies made in different regions, which have shown that the optimum values of PV for reducing variability in areas with high solar resource are above 50% [44,45]. Certain studies give different results depending on the time frequency analysed [43].…”

“…where PV and W are the productivity of wind (Wprod) and photovoltaic (PVprod) series respectively, each one divided by its average in order to scale mean productivity to 1 as in [43][44][45]. The share coefficients go from 0 to 1 (equivalent to an energy share of 0 to 100%) and are related to each other with the next expression:…”

The progressive energy transition to systems with higher shares of renewable energy is particularly important in islands regions, which are largely dependent on energy imports. In this context, to assess the impact of climate change on renewable energy resources during the 21st century is crucial for polycimakers and stakeholders. In this work, we provide an overview of wind and photovoltaic (PV) resources, its variability and complementarity between them, as well as their future changes, in the Canary Islands and surrounding areas. Variability is assessed through the analysis of energy droughts (low-productivity periods). In addition, a sensitivity test is performed to find the optimal combination of PV (photovoltaic) and wind that reduce energy droughts and the persistence of that conditions at a local scale. A set of climate simulations from the MENA-CORDEX runs are used, in present and future climate (2046–2065, 2081–2100) for two different scenarios (RCP2.6, RCP8.5). Results show different changes in wind productivity depending on the scenario: a decrease in RCP2.6 and an increase in the RCP8.5. PV experienced a subtle decrease, with some exceptions. Changes in variability are small and the complementarity test shows that high shares of PV energy (above 50%) reduce both, energy droughts and the persistence of drought conditions.

“…2, this method simulates the uncertainty of hydropower/PV/load in several scenarios, which is more accurate than six scenarios. Reference [15] considers that the factor analysis method is suitable for the classification of renewable energy complementary systems, thus proposes a power classification method for different energy sources, which is especially suitable for large areas, and proposes a multivariable renewable energy complementary output scheduling optimization model, which is helpful to the modeling of multi-energy complementary operation and scheduling.…”

The hydro-photovoltaic complementarity is an important operation mode to promote the grid-connected absorption, and one of the main directions of solar energy development and utilization in the future. The paper expounds the principle of hydro-photovoltaic complementarity and the influence of the installed ratio on economy, also summarizes and analyzes the research results of hydro-photovoltaic complementary system operation scheduling methods. In view of the uncertainty of hydro-photovoltaic complementary generation, the paper proposes several suggestions and expectations for the study of hydro-photovoltaic complementarity, to provide ideas for improve the economy and reliability of short-term and large-scale hydro-photovoltaic complementary operation.

“…In general, complementarity can be defined as the relationship between two or more independent phenomena whose simultaneous operation creates more benefits than individual operations [35]. Complementary RES studies can help design hybrid systems and overcome obstacles to help produce more reliable and cleaner energy [36]. Therefore, understanding the complementarity and diversity of renewable energies is a key foundation for achieving a high penetration level without compromising the power system's reliability and economy [32].…”

Renewable energy sources play an important role in providing clean energy for future electricity networks. As the penetration level of these resources grows, their integration with the grid will be more challenging. Each renewable energy source has different inherent characteristics that, if appropriately used in the generation mix, could complement each other and create many technical and economic benefits for the power system. Usually, renewable energy resource complementarity studies are carried out with the objectives of smooth effect, reducing the need for storage and load tracking. In this study, the economic complementarity approach is introduced with the help of a Mixed integer nonlinear programming (MINLP) model. This approach can integrate renewable and storage energy sources with the grid and determine the optimal capacity of these resources in complementary used mode. The results show that the proposed method always imposes the system's lowest annual operation and investment costs.
