Monforti et al. assessed the complementarity between wind and solar resources in Italy through Pearson correlation analysis and found that their complementarity can favourably support their integration into the energy system. Jurasz et al. simulated the operation of wind-solar HES for 86 locations in Poland.

Which cluster of wind power stations exhibit the weakest complementarity with radiation?

Analysis of the matrix reveals that the 4th, 5th, 7th, and 8th clusters of wind power stations exhibit the weakest complementarity with the radiation of photovoltaic stations. In contrast, the 5th, 7th, 8th, and 10th clusters of photovoltaic stations similarly demonstrate poor complementarity with the wind speed of wind power stations.

What is the complementary coefficient between wind power stations and photovoltaic stations?

Utilizing the clustering outcomes, we computed the complementary coefficient R between the wind speed of wind power stations and the radiation of photovoltaic stations, resulting in the following complementary coefficient matrix (Fig. 17.).

Is there a complementarity between wind and solar energy?

Studying the complementarity between wind and solar energy is crucial for optimizing the use of these renewable resources. Multi-energy compensation systems need to consider multiple metrics, and current research relies on the correlation of single metrics to study this complementarity.

Do wind and solar resources have a complementarity metric system?

To this end, we propose a novel variation-based complementarity metrics system based on the description of series' fluctuation characteristics from quantitative and contoured dimensions. From this, the complementarity between wind and solar resources in China is assessed, and the trend and persistence are tested.

How do we evaluate the complementarity of wind and solar resources?

Previous studies have primarily used the Pearson correlation coefficient (CC) and similar metrics to evaluate the complementarity of wind and solar resources. For instance, Che et al. directly calculated Pearson CC to analyze the complementarity between wind and solar power and between wind and hydropower.

How does South Korea support its energy transition?

South Korea has also implemented the legislative framework necessary to support its energy transition. The Energy Act (2006) and Framework Act on Low Carbon and Green Growth (2010) represent the basis for energy planning, including the Energy Master Plan which is updated every 5 years.

What is Korea's strategy regarding renewables integration?

Korea's strategy regarding renewables integration is pragmatic and business-oriented like in Taiwan, China or Japan. Korea aims to pursue IT-enabling of its power grid with a modular approach to smart grid construction.

Is Korea a powerhouse for grid-connected battery systems?

Korea counts as the global powerhouse for grid-connected battery systems. Korean manufacturers LG Chem, Samsung SDI are world leaders with strong exports; the domestic market is expected to grow at an average annual rate of 10%, from 300 bil-lion KRW (228 million EUR) in 2016 to 440 billion KRW (336 million EUR) in 2020.

What is the power system voltage in Korea?

Korea's power system voltage levels are relatively high at 765kV, 345kV, 154kV and 22.9kV. This contributes to reliability of the power sys-tem and reduces the transmission losses. In 2016, Korea's transmission-to-loss ratio was only 3.59%.

Why is Korea's electricity system isolated?

Korea's electricity system is isolated due to its geographical and political situation. In 2017, the total power generation capacity in Korea stood at 113,667 MW. Thereof, the highest share was coal (32%), and followed by natural gas (31.3%), nuclear (19.8%), renewables (8.5%), hydropower (4%) and oil (3.4%) (KPX 2018).
