建设新型电力系统目标下的湖南省中长期电源优化配置研究OACSTPCD

In the context of accelerating the construction of a new power system and helping the planning and construction of a new energy system,the power supply structure of Hunan Province is gradually changing from"Hydro and thermal power coordinating"to a new pattern of new energy as the main element of electricity.Considering the randomness and volatility of new energy power generation,the optimization and reconstruction of the energy structure of Hunan power grid and the further development of regulating power supply are very important for the safe operation and the clean development of power system.In this paper,the new power system operation simulation model is used,and the economic model of power supply expansion optimization is established by comprehensively considering the construction and operation cost of power supply expansion,the new energy consumption and other factors.Taking Hunan power grid as the model application example,the allocation of long-term power resources in the power system is analyzed in depth,and the recommended scheme for the optimal allocation of long-term power supply in the system is clarified through technical and economic comparison.
