Season of wind power hydropower and photovoltaic power generation

Can hydropower compensate for wind and solar power?

Author to whom correspondence should be addressed. Hydropower compensating for wind and solar power is an efficient approach to overcoming challenges in the integration of sustainable energy. Our study proposes a multi-objective scheduling model for the complementary operation of wind–photovoltaic–hydro systems.

How can a seasonal difference transformation be applied to wind and solar power?

The time series of wind and solar power generation has a seasonal change trend, and a seasonal difference transformation can be applied to it. A seasonal difference operator is introduced, where with S as the period. Then, the seasonal ARIMA model is

How can seasonal differences affect electricity production?

Diminishing seasonal differences could have both positive and negative implications for the electricity production sector: increased wind speed in the Summer can improve wind power production and increased solar radiation in Winter could aid solar power, both of which suffer from reduced electricity production in their respective off-season.

Can wind power generation forecasts be forecasted at seasonal timescales?

While forecasts of wind power generation at lead times from minutes and hours to a few days ahead have been produced with very advanced methodologies (e.g. dynamical downscaling, machine learning or statistical downscaling [ 17 ]), a number of difficulties make the provision of generation forecasts at seasonal timescales challenging.

How does potential electricity production match the consumption of solar and wind power?

The potential electricity production matches the consumption by spatiotemporal management of suitable shares of solar and wind power complemented with the present hydropower.

Can cascade hydropower be combined with wind and solar energy?

The joint operation with wind and solar energy also brings new challenges to reservoir scheduling, and cascade hydropower needs to coordinate with the peak load operation of the new power system with wind and photovoltaic integration. Previous research has primarily focused on single-objective models.
