【摘要】 针对风光等不确定性电源并网后对电力系统带来不确定性的影响，并引起了大量弃风弃光弃水的问题，以提高可再生能源消纳能力为目标，提出一种考虑电源灵活性与互补性的多能源电力系统互补协调分层优化调度方法。首先，对电源的灵活性供给与灵活性需求进行量化分析；其次，从提升系统可再生能源消纳和节能的角度考虑，对系统的互补目标性、互补需求性分别进行分析；再次，基于互补指标和灵活性裕度约束，建立以可再生能源消纳量最大为目标的多能源电力系统互补协调分层优化调度模型；然后，提出基于互补性指标和各能源灵活性约束的分层求解策略；最后，基于西北某省实测数据进行实例分析，证明了所提调度方法和求解策略正确、有效。更多还原

【Abstract】 In view of the uncertain impact of wind, solar and other uncertain power sources on the power system after being connected to the grid, it has caused a large number of wind and solar and water abandonment problems. With the goal of improving the capacity of renewable energy consumption, a power source is considered. Flexible and complementary multi energy power system complementary coordination hierarchical optimization dispatching method. First of all, a quantitative analysis of the flexibility of power supply and demand for flexibility. Secondly, from the perspective of improving the system’s renewable energy consumption and energy conservation, the system’s complementary objectives and complementary needs are considered. The sex is analyzed separately. Thirdly, based on the constraints of complementary indicators and flexibility margins, a multi energy power system complementary and coordinated hierarchical optimal dispatch model with the goal of maximizing the consumption of renewable energy is established. Then, a hierarchical solution strategy based on complementary indicators and energy flexibility constraints is proposed. Finally, an example analysis based on the measured data of a certain province in Northwestern China proves that the scheduling method and solution strategy proposed in this paper are correct and effective.更多还原
