热电机组比重及热负荷对风电消纳率影响的研究
Research on the impact of the proportion of thermal power generating units and heat load on the wind power accommodation rate
摘要
Abstract
In order to study the power grid’s acceptance ability of the wind power, according to thermal and electrical load as well as wind power output characteristics of typical day in winter, this paper proposes an optimal heat and electricity load distribution plan for power structure in independent grid containing thermoelectric units, the pure condensing turbine and wind turbine units, and studies the effect of the heat load on the wind power accommodation rate according to the optimization results. Based on modeling on the pure condensing unit and condensate pumping unit of coal units, this paper constructs an energy-saving scheduling model with an objective function of minimum coal consumption. In this model, electrical load is balanced by the whole network units, the heat load is balanced by each thermal power plant on the spot, and the abandoned wind is punished. Example analysis results show that the change of heat load will lead to the change of the system optimization scheduling and wind power accommodation rate.关键词
