摘要
随着负荷峰谷差的增大和大规模间歇性新能源的接入,仅靠电源侧的调度可能无法满足系统的调峰要求,采用电源-负荷协同调度是可行的解决方法。从含风、水、火、气多类型能源的传统调度模型出发,建立了电源-负荷协同调度模型。模型考虑了可调度负荷的上下限约束和日停电电量约束,并采用内点法求解该模型。算例计算表明,电源-负荷协同调度方式可以有效地提高电网接纳新能源的能力。
With the increase of peak-valley load difference and the integration of large-scale intermittent energy,dispatching merely on power supply may not meet the requirement of system peak regulation,and source-load coordinated dispatch is a feasible solution. This article sets up a source-load coordinated dispatch model based on conventional dispatch models including wind,hydro,thermal and gas power. The model considers the upper and lower constraints and the power consumption constraints of schedulable load,and can be solved by the interior point method. The cases showthat the proposed method can improve the accomodation capability of newenergy sources.
