摘　　要：针对混合电力系统安全、经济和可持续供电需求,提出一种混合电力系统联合优化调度模型。综合分析风电、太阳能光伏发电和负荷预测的不确定性、电网安全要求以及不同电源的运行特性;建立考虑风电、太阳能光伏、梯级水电、火电和抽水蓄能等混合电力系统联合优化调度模型;以IEEE39节点系统为基础,结合中国某省电网的功率构成比、发电机组分布和流域分布,构建一个混合电力模拟系统;对不同水力、风力和负荷条件下的自然情景进行调度仿真。结果表明:仿真结果符合实际运行情况,所提模型为混合电力系统最优调度方案、安全管理及稳定运行提供了一定借鉴。A joint optimal dispatch model for hybrid power systems is proposed to meet the demand for secure,economical and sustainable power supply.The uncertainty of wind power,solar photovoltaic power generation and load forecasting,the security requirements of power grid and the operation characteristics of different power sources are comprehensively analyzed,and a joint optimal dispatching model considering wind power,solar photovoltaic power,cascade hydropower,thermal power,pumped storage and other hybrid power systems is established;Based on the IEEE 39-bus system,a hybrid power simulation system is constructed by combining the power composition ratio,generator distribution and basin distribution of a provincial power grid in China;The simulation results of natural scenarios under different hydraulic,wind and load conditions show that the simulation results are in line with the actual operation situation,and the proposed model provides a reference for the optimal dispatching scheme,security management and stable operation of the hybrid power system.
