摘要: 在我国“双碳”目标发展战略背景下，加快了以风光电为主的新能源发展速度，给电网调度运行带来了极大挑战，弃风弃光成为亟待解决的问题。与此同时，近年飞速发展的大容量储能以优异的充/放电调节特性与调节能力为新能源消纳提供了新途径。为此，本文提出了基于储能参与调节的源–储协调优化调度方法，首先分析了储能参与调节的源–储协调调度对新能源消纳的影响机理；进而考虑储能参与调节，以新能源消纳最大为目标建立源–储协调优化调度模型并进行求解，最后进行实例仿真计算，验证了本文所提源–储协调优化调度方法对新能源消纳的有效性。

Abstract: In the background of China’s “dual-carbon” target development strategy, the development of new energy, mainly wind power and photovoltaics, is accelerating. This has brought great challenges to the scheduling and operation of the power grid, and abandoning wind and light has become an urgent problem to be solved. At the same time, the rapid development of large-capacity energy storage in recent years provides a new way for new energy consumption with excellent charge/ discharge adjustment characteristics and adjustment capabilities. To this end, this paper proposes a source-storage coordinated optimal scheduling method based on improving the capacity of new energy consumption. Firstly, the influence mechanism of source-storage coordinated scheduling on new energy consumption is analyzed. Then, the source-storage coordinated optimal scheduling model was established and solved with the goal of maximizing the consumption of new energy. Finally, a case analysis is carried out on the background of large-scale wind power photovoltaic integration into the power grid, which verifies the effectiveness of the source-storage coordinated optimal scheduling method proposed in this paper for the consumption of new energy.
