Power grid dispatching optimization system and method based on multiple time scales

Abstract

The invention provides a power grid dispatching optimization system and method based on multiple time scales. The system comprises a marketing master station and a dispatching master station. The marketing master station is used for data acquisition, analysis and prediction of the load to obtain first schedulable resource information, and is also used for sharing the first schedulable resource information with the scheduling master station. The scheduling master station is used for correcting a scheduling plan through a multi-time scale scheduling strategy according to the first schedulable resource information, the new energy real-time power and the energy storage state, is used for carrying out security check on the corrected scheduling plan, and is also used for carrying out quantitative evaluation on the interaction effect after the load participates in power grid dispatching according to a preset interaction evaluation index system. Therefore, according to the power grid dispatching optimization system based on the multiple time scales, through information sharing of the dispatching master station and the marketing master station, flexible regulation and control of various loads are achieved according to service requirements of different scenes, the safety level and operation benefits of a power grid are effectively improved, and the operation flexibility of the power grid is enhanced.

Description

technical field [0001] The invention relates to the technical field of power system intelligence, in particular to a multi-time scale-based power grid scheduling optimization system and method. Background technique [0002] With the increasing proportion of new loads with dual characteristics of source and load such as electric vehicles and energy storage equipment, new forms of energy consumption such as load aggregators and smart buildings continue to emerge, clean energy capacity and penetration rate continue to grow, and UHV AC / DC hybrid With the rapid development of interconnected grids, the forms of power supply and demand are increasingly diversified. The safe and orderly operation of the power grid is facing unprecedented challenges, and the difficulty of power grid regulation is increasing. The main performance is as follows: [0003] 1. Due to the geographical concentration, season concentration and time period concentration of clean energy, coupled with the lack...
