The latest requirements for wind and solar complementary ratios for solar container communication stations

Do wind and solar energy resources need more flexible resources?

In the context of energy conservation and emission reduction, the integration and consumption of large-scale wind and solar resources is an inevitable trend in future energy development. However, with the increase of wind and solar grid-connected capacity, the power system also requires more flexible resources to ensure safe operation.

What are the operating characteristics of a photovoltaic-hydropower complementary system?

Literature (Cuiping et al., 2017) evaluated the operating characteristics of the photovoltaic-hydropower complementary system based on indicators such as the abandoned light ratio, the ratio of thermal power to load, and grid-connected revenue.

Should wind power be relying solely on thermal power?

When the penetration rate of wind power increases to a certain extent, relying solely on thermal power to cope with the uncertainty of wind and solar output will lead to frequent starting and stopping of thermal power units, threatening the safety, stability, and economy of the power grid operation (Ye et al., 2023).

What are the penalty cost coefficients for curtailed wind and photovoltaic power?

In the formula Eq. 8: N i 4, f and N i 4, p are respectively the penalty cost coefficients for curtailed wind and photovoltaic power; I q is the total number of equipment for curtailment; Q i 4, t f and Q i 4, t p are the amounts of curtailed wind and photovoltaic power at the corresponding moments.
