Abstract

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.

高比例可再生能源输端电网多源协调周时标发电优化方法研究

为了充分利用各种电源的周时标运行特性和互补特性，本文对风电、光伏、聚光太阳能和火电在周时标上的运行特性和互补特性进行了研究。通过研究风电和光伏全年日发电量历史数据，将风电和光伏日发电量划分为典型日发电场景，得到周时间尺度下互补发电组合模式。结合优化模型，提出了一种周时间尺度单元的组合优化方法。最后，通过某区域电网的实际计算实例，验证了本节提出的机组组合优化方法对风电-光伏-聚光光热联合发电周规划的有效性。
