Abstract

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 show that the proposed method can improve the accomodation capability of new energy sources.

Key words

source-load coordinated dispatch / interruptible load / peak regulation capacity / intermittent renewable energy
