Power peak regulation method, dispatch center and power peak regulation system

Abstract

The invention provides a power peak shaving method, a dispatch center and a power peak shaving system. The method includes: obtaining the next day's predicted load, the next day's predicted new energy output, and the next day's high-energy load information that can participate in dispatching; according to the obtained The next day's forecasted load, the next day's forecasted new energy output, and the next day's high-energy load information that can participate in dispatching can generate a day-ahead dispatching plan under the peak-shaving mode in which only conventional energy power plant units participate; Whether there is a situation of discarding new energy output on a daily basis; if so, generate a day-ahead scheduling plan in which conventional energy power plant units and high energy loads participate together; based on the day-ahead scheduling plan and battery energy storage device output plan for conventional energy power plants and new energy power plants Intra-day correction can improve the ability to track load changes, increase the flexibility of adjustment, reduce the limitations of discrete adjustment of high-energy loads on peak regulation, and effectively reduce system operating costs.

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 characteristics of wind power output. , 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 ...
