Research on Medium-and Long-term Coordinated Operation Method of Hydro-photovoltaic Complementary System in Upper Reaches of Jinsha River
摘要
Abstract
Giving full play to the flexible regulation capability of basin-scale cascade hydropower stations can realize the coordinated operation of the hydro-photovoltaic(PV)complementary system,which is also an important measure to enhance renewable energy accommodation level.Taking the cascade hydropower stations and PV stations in the Sichuan-Xizang section of the upper Jinsha River that are in the pre-planning stage as research object,a medium-and long-term coordinated operation optimization model is established with the objective of maximizing the power generation of the hydro-PV complementary system,so as to assess the accommodation level of sending power from the hydro-PV complementary system.The operation constraints of the cascade hydropower stations,PV stations and direct current(DC)transmission line are also taken in account.The numerical analysis is performed to calculate the maximum installed capacity of PV stations and the related typical daily sending power curves under different planned installed capacity of cascade hydropower stations.Furthermore,the model verification and sensitivity analysis are carried out from the aspects of the wet-flat-dry level year,the maximum daily adjustment range of DC transmission line and whether to configure the pumped-storage power stations.The results indicate that the hydro-PV generation output in the Sichuan-Xizang section of the upper Jinsha River is complementary in the seasonal scale of natural resources and the intra-day scale of power regulation,and improving the regulation capability of cascade hydropower stations and DC transmission line,or configuring the pumped-storage power stations can lead to a further increase in the maximum acceptable installed capacity of PV stations.关键词
