Real-time power generation plan optimization method considering northern Shaanxi cascade section limit linkage adjustment

Abstract

The invention discloses a real-time power generation plan optimization method considering northern Shaanxi cascade section limit linkage adjustment. The method comprises the following steps: based onvarious basic data of a real-time power generation plan, constructing a network-province two-stage real-time power generation plan coordination optimization model in a generalized tie line mode, and providing a unit initial plan value and a section initial tide value for joint optimization of the real-time power generation plan and Shaanbei cascade section limit. According to the method, based onvarious basic data of a real-time power generation plan, a unit initial plan and a section initial tidal current value, a real-time power generation plan optimization model considering northern Shaanxi cascade section limit linkage adjustment is constructed; an optimization target is introduced into the Shaanbei virtual subarea, so that the new energy wind curtailment amount is minimum; constraints such as a Shaanbei subarea cascade section and a the central Shaanxi plain subarea admitting ability are introduced into constraint conditions, combined optimization of unit output and stable section limits is achieved, the Shaanbei subarea new energy consumption potential of Shaanxi province is fully excavated, the utilization rate of the Shaanbei cascade section is increased, and the lean level of northwest regional power grid new energy scheduling is 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 ...
