Trans-provincial peak regulation auxiliary service market clearing method considering power grid safety constraints

Abstract

The invention discloses a trans-provincial peak regulation auxiliary service market clearing method considering power grid safety constraints, and belongs to the technical field of power system scheduling. The method comprises the following steps: (1) obtaining trans-provincial peak regulation auxiliary service basic data, wherein the trans-provincial peak regulation auxiliary service basic data comprises equipment basic parameters, energy storage environment parameters, a current operation state, load historical data, response historical data, power utilization load prediction, energy storage output expectation, energy storage technical characteristics, response economy and response reliability; (2) establishing a multi-objective optimization scheduling model, wherein the load peak-valley difference should be reduced as much as possible when a power grid scheduling center formulates a scheduling strategy, and meanwhile, loads in a local time period are smoothened to reduce frequent start and stop of a unit; (3) optimizing and solving the obtained unit power generation plan: considering all network monitoring elements, and carrying out security check on each time period in the scheduling period. A feasible theoretical and technical guarantee is provided for clearing of a trans-provincial peak regulation auxiliary service market.

Description

technical field [0001] The invention belongs to the technical field of power system dispatching, and in particular relates to a method for clearing a cross-provincial peak-shaving auxiliary service market in consideration of power grid security constraints. Background technique [0002] The market-oriented reform of the power industry continues to deepen, promoting the transformation of power supply from a regulated method to a market model. The market-oriented operation of frequency regulation auxiliary services can encourage market members to provide frequency regulation services more proactively, improve the allocation efficiency of frequency regulation resources, improve the supply quality of frequency regulation resources, and reduce the purchase cost of frequency regulation resources. meaning. [0003] The marketization of frequency modulation ancillary services will become the development direction of the electric power industry, and the power market at different sta...

AI Technical Summary

Problems solved by technology

[0004] Due to the lack of a domestic energy market, in the absence of a main energy market at present, there is a problem that the clearing results of the independent transaction of frequency regulation auxiliary services are difficult to actually implement in the power grid

In particular, the security issues during the operation of the domestic power grid are usually severe, and the operating status of the frequency modulation unit under the clearing of the frequency regulation market has the risk of being difficult to meet the security constraints of the power grid
