Power Generation Scheduling for Long Distance Consumption of Wind-Solar-Thermal Power Based on Game-Theory

Abstract

With the fast development trend of renewable resources, peculiarly solar power and wind power generation, because the centralized processing capacity of the local power grid is insufficient, long-distance power transmission will become an important way for centralized processing of new energy. The article proposes a wind-light-heat mixer that uses high-voltage DC transmission lines (TLs) for long-distance centralized absorption, which flexibly uses the diversity of solar and wind energy generation in time and zone and can also use power plants (PPs) with good reliability and improve reliability indicators. The two-tier promotion strategy based on the non-cooperative game method is used to maximize the profit of the PP according to the change of the bidding strategy. The PP in the sender system is at the top level, and the coordinate system is at the lower level. In addition, a cost entity model is proposed, which considers logistics costs, carbon emissions costs, and state subsidies. Finally, the feasibility analysis of the two-tier optimization method was verified based on several simulations.
