摘　　要：随着风电、光伏并网规模不断增大,中国新能源消纳问题逐渐凸显,为了减少弃风弃光现象发生,准确评估电力系统的新能源消纳能力,对于高比例新能源电网的合理规划和中长期稳定运行具有重要的现实意义。首先对新能源消纳原理进行了理论分析;然后基于时序生产模拟法建立了综合考虑系统直流潮流、旋转备用容量、常规机组出力、外送功率、电化学储能等约束的新能源消纳能力评估模型;最后以IEEE30节点系统作为算例,基于新疆地区实际数据对系统新能源消纳水平进行了评估,从模型求解、模型对比和参数灵敏度分析三个方面验证了所提电力系统新能源消纳能力评估模型的准确性和有效性。With the increasing scale of wind power and photovoltaic grid connection,the problem of renewable energy accommodation in China has gradually become prominent.In order to reduce the occurrence of wind and light abandonment,it is of great practical significance to accurately evaluate the renewable energy accommodation capacity of power system for the rational planning and medium and long-term stable operation of high-proportion renewable energy power grid.The principle of renewable energy accommodation was analyzed theoretically.Then,based on the time series production simulation method,a renewable energy accommodation capacity evaluation model considering the constraints of DC power flow,spinning reserve capacity,conventional unit output,transmission power and electrochemical energy storage was established.Finally,using the IEEE30 node system as an example,the renewable energy accommodation level of the system was evaluated based on the actual data in Xinjiang,and the accuracy and validity of the proposed renewable energy accommodation capacity evaluation model of the electric power system were verified from the three aspects of the model solving,the model comparing and the parameter sensitivity analysis.
