未来，在高比例可再生能源接入的电力系统中，风、光高比例协同发展，储能、可中断负荷等灵活性资源在电网调峰运行中将发挥重要作用，为此提出了一种考虑灵活性资源的风光综合消纳规划方法。在电源开发能力的限制下，结合专家经验，优先开发调峰电源及储能、可中断负荷等灵活性资源，最大限度增加系统可调节能力，并考虑合理的弃电空间，提升接纳新能源能力。在平衡方法上，基于对地区负荷及风光特性的挖掘，选择平衡校验时段。通过历史数据回测，判断调峰平衡时段内风、光出力率，并通过对典型日风光弃电功率积分，分别计算弃风率和弃光率。该方法综合考虑系统容量充裕度和新能源消纳能力，构建了基于平衡方法的风光综合消纳规划方法，并考虑一定弃电空间，促进新能源发展。最后，以东北某省级电网2025、2030年电源规划为算例，验证了上述模型和算法的有效性。

In the future, high proportion of renewable energy will be connected to the power system, wind and photovoltaic are developing in a high proportion, and flexible resources such as energy storage and interruptible load play an important role in peak load regulation. In this paper, a planning method for wind power and photovoltaic absorption considering flexible resources is proposed. Under the limitation of power development capacity, combining with the experience of experts, we give priority to the development of peak-regulating power supply, energy storage, interruptible load and other flexible resources, maximize the adjustable capacity of the system, and consider reasonable power abandoning space to improve the capacity of accepting new energy. On the balance method, the period of balance check is selected based on the regional load, wind and photovoltaic characteristics. Based on the historical data, the wind and photovoltaic output rate in the peak shaving equilibrium period is judged, and the wind and photovoltaic abandonment rate is calculated respectively by integrating the typical daily power abandonment. This method considers the adequacy of system capacity and the capacity of new energy absorption comprehensively, and constructs a comprehensive planning method of wind and solar energy absorption based on the balance method. It also considers certain power abandonment to promote the development of new energy. Finally, an example of 2025 and 2030 power supply planning for a provincial power grid in Northeast China is given to verify the effectiveness of the above model and algorithm.
