A real-time power generation planning optimization method considering the linkage adjustment of cascade section quotas in northern Shaanxi

Abstract

The invention discloses a real-time power generation plan optimization method considering the linkage adjustment of the cascade section limit in northern Shaanxi, which includes: based on various basic data of the real-time power generation plan, constructing a two-level real-time power generation plan coordination optimization model of the grid and province under the generalized tie line mode, for The joint optimization of real-time power generation plan and northern Shaanxi cascade section quota provides unit initial plan value and section initial tidal current value; based on various basic data of real-time power generation plan, unit initial plan and section initial tidal current value, constructs the cascade section quota linkage in consideration of northern Shaanxi The adjusted real-time power generation plan optimization model, the optimization goal is introduced into the northern Shaanxi virtual zone to minimize the amount of new energy abandoned air, and the constraints are introduced into the cascading sections of the northern Shaanxi zone and the acceptance capacity of the Guanzhong zone to realize the joint optimization of unit output and stable section quotas, fully The potential of new energy consumption in the northern part of Shaanxi Province has been tapped, the utilization rate of cascade sections in northern Shaanxi has been improved, and the lean level of new energy dispatching in the northwest regional power grid has been improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a real-time power generation plan optimization method considering the joint adjustment of quotas of cascading sections in northern Shaanxi. Background technique [0002] As a regional power grid rich in new energy, in order to promote the consumption of new energy, the Northwest Regional Power Grid will realize the online operation of the day-ahead power generation plan in 2012, the real-time power generation plan in 2014, the short-term trading platform in 2015, and the short-term power generation plan in 2016. The function of the trading platform has been improved, and core functions such as real-time transaction forecasting and transaction verification have been developed. From 2017 to 2018, further research and development of cross-provincial peak-shaving, cross-regional spot and new energy consumption platforms will promote the ...
