A method and system for trade inter-provincial peak shaving auxiliary service

Abstract

The invention discloses an inter-provincial peak shaving auxiliary service transaction method and system. The method comprises the following steps: receiving provincial and municipal tie line outlet pre-power generation plan and preparing provincial and municipal pre-power generation plan, including determining the peak shaving demand of each provincial and municipal next day or the peak shaving margin of each provincial and municipal regulating unit; declaring the peak-shaving demand of each province or municipality or the peak-shaving margin of each provincial or municipal pipe-regulating unit on the next day; Releasing the demand of each province and city for peak shaving on the next day; Receiving the peak-shaving capacity and peak-shaving price declared by the power plant with peak-shaving margin on the next day and clearing the peak-shaving market according to the peak-shaving demand of each province and city on the next day; Purchasing peak shaving auxiliary service provincial and municipal clearing power, sellling peak shaving auxiliary service management unit clearing power for peak shaving cost allocation and settlement according to the clearing price in each period. Theinvention encourages power generation enterprises to actively participate in peak shaving auxiliary service by economic means, improves the peak shaving capacity of the unit, releases peak shaving resources, alleviates the peak shaving difficulty of the power network, and improves the new energy consumption capacity among provinces.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching, in particular to an inter-provincial peak regulation auxiliary service transaction method and system. Background technique [0002] In recent years, the peak-shaving contradictions of regional power grids have become increasingly prominent, mainly due to factors such as insufficient DC peak-shaving capacity outside the region during the flood season, slow valley load growth, increasing peak-to-valley difference in power consumption year by year, and rapid development of new energy in the region; The hard way is to perform cross-save swaps. However, there are many problems in the implementation process, such as the low enthusiasm of power generation enterprises to participate in the construction of peak shaving capacity, the low enthusiasm of provinces and cities with peak shaving difficulties to reduce the replacement volume, the difficulty in returning the replacement power, and t...

Problems solved by technology

However, there are many problems in the implementation process, such as the low enthusiasm of power generation enterprises to participate in the construction of peak shaving capacity, the low enthusiasm of provinces and cities with peak shaving difficulties to reduce the replacement volume, the difficulty in returning the replacement power, and the increase of unnecessary inter-provincial power flows. It is conducive to the safety of power grid operation, and it is also not conducive to energy saving and emission reduction.
