Research on Optimization Method of Multi-source Coordination Weekly Time Scale Power Generation in High-Proportion Renewable Energy Transmission-End Power Grid

In order to take full advantage of the weekly time scale operating characteristics and complementary characteristics of various powers, this paper studies the operating characteristics of wind power, photovoltaic, concentrating solar and thermal power on the weekly time scale, and the complementary operating characteristics. By studying the historical data of wind power and photovoltaic daily power generation throughout the year, the daily power generation of wind power and photovoltaic is divided into typical daily power generation scenarios, and complementary power generation combination modes under weekly time scales are obtained. By combining optimization model, a combination optimization method for weekly time scale units is proposed. Finally, through the actual calculation example in a certain area grid, the effectiveness of the unit combination optimization method proposed in this section for the weekly planning of wind power-photovoltaic-concentrating solar-thermal power combined power generation is verified.
