Embodiment

[0085] like figure 1 As shown in the figure, a method for joint clearing of main and auxiliary power grids in a regional interconnected power grid considering the reserve capacity of generation and utilization resources is proposed, which includes the following steps:

[0086] S1: The power generation side and the power consumption side in the sub-area evaluate their own adjustment capabilities;

[0087] S2: Entering the day-ahead market declaration link, all power generators, user-side demand response and energy storage determine their respective day-ahead bidding information, and at the same time determine the load information;

[0088] S3: The sub-regional power grid determines the preliminary clearing plan before the day before, and pushes the information to the regional center; the regional center conducts secondary coordination for each region, and returns the winning bid information to the sub-region after adjustment;

[0089] S4: Each sub-region returns the bid-winnin...

Abstract

The invention relates to a regional interconnected power grid main and auxiliary joint clearing method considering the power generation and utilization resource standby capability, and belongs to the technical field of regional power grid management, and the method comprises the following steps: a power generation side and a power utilization side in a sub-region assess the self adjustment capability; entering a day-ahead market declaration link, determining respective day-ahead bidding information by all power generators, user side demand responses and energy storage, and determining load information at the same time; the sub-regional power grid determines a preliminary day-ahead clearing scheme and pushes information to the regional center; the area center carries out secondary coordination on each area, and bid winning information is returned to the sub-areas after adjustment; each sub-region returns bid-winning information to a power generator, a user side demand response and an energy storage operator, and each department preliminarily executes the bid-winning information according to a day-ahead scheme. According to the method, the regional power grid market can be cleared more efficiently, clearing schemes of various generator resources, user side demand response resources and energy storage resources in the current and real-time main and auxiliary markets in the region are optimized and calculated, and absorption of clean energy is promoted.

Description

technical field [0001] The invention belongs to the technical field of regional power grid management, and in particular relates to a main-auxiliary joint clearing method for regional interconnected power grids considering the backup capability of generation and utilization resources. Background technique [0002] The large-scale connection of new energy sources to the grid has made the phenomenon of system-level abandonment of wind and light become more and more serious, and at the same time, the shortage of backup resources of the power grid has further increased. However, as the system load growth rate becomes more and more stable, blindly increasing the grid reserve capacity is not conducive to the economics of grid operation. Therefore, in order to solve the gap of spare resources, it is necessary to consider both "open source" and "throttling". From the "open source" level, the main consideration is to motivate existing adjustable resources to provide backup support f...
