Electric power peak shaving method, dispatching center and electric power peak shaving system

Abstract

The invention provides an electric power peak shaving method, a dispatching center and an electric power peak shaving system. The method comprises the following steps: obtaining next-day predicted load, next-day predicted new energy output and next-day high-energy load information capable of participating in dispatching; generating a day-ahead scheduling plan under a peak regulation mode in whichonly a conventional energy power plant unit participates according to the obtained next-day predicted load, the next-day predicted new energy output and the next-day high-energy load information capable of participating in dispatching; according to the day-ahead scheduling plan, judging whether a case of discarding new energy output exists the next day; if so, generating a day-ahead scheduling plan in which the conventional energy power plant unit and high-energy load jointly participate; and carrying out intra-day correction on output plans of a conventional energy power plant and a new energy power plant based on the day-ahead scheduling plan and the battery energy storage device. Capability of tracking load change can be enhanced; the adjustment flexibility can be enhanced; the limitation of high-energy load discrete adjustment on peak regulation can be reduced; and the system operation cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a power peak regulation method, a dispatch center and a power peak regulation system. Background technique [0002] Since the beginning of the 21st century, wind power has flourished as the main form of new energy. Different from power sources such as thermal power, hydropower, and nuclear power, wind power output has intermittent, fluctuating, and anti-peaking characteristics, and has the characteristics of low capacity reliability and poor predictability. The large-scale centralized development of wind power has highlighted these wind power output characteristics. , The power system is facing huge peak load pressure. In the traditional power system, planning or operation decisions mainly consider the uncertainty of the load, while in the new energy power system, the proportion of intermittent power generation is relatively high, so the power system presents significant ran...
