Abstract

The invention discloses a power dispatching method suitable for a spot market, relates to the field of power dispatching, and aims to maintain system stability better. The method comprises the following steps: configuring a power grid system; distributing the power grid system into more than two sub-sections, arranging an IED in each sub-section, and connecting the IEDs with a dispatching center through a network; setting a multi-stage IED; and setting another IED adjacent to one IED as a secondary IED, and setting IEDs adjacent to the secondary IED of the IED as a tertiary IED. By arranging the multi-stage IED, the power supply stability of the power grid system can be improved, and the problem of unstable power during supply and demand adjustment of a single sub-section or multiple sub-sections is avoided; by setting the step of estimating the electricity demand, the load and the power supply quantity can be reasonably and stably adjusted in advance, the adjustment amount of power supply in unit time is reduced as much as possible, and the stability of the system is further maintained.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to a power dispatching method suitable for spot markets. Background technique [0002] Power dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. The rationality and stability of power dispatching is a key condition for ensuring people's quality of life. [0003] After searching, the Chinese patent application number is CN200910237978.9, which discloses a time-series progressive power dispatching method, which belongs to the field of electric power dispatching automation technology, including: setting three levels of monthly power generation plan, weekly power generation plan, and daily power generation plan Sequence link of power dispatching; the dispatching center constructs a monthly power generation plan model for the next ...
