基于来水不确定性的梯级水电站负荷调整耦合模型——以锦官电源组梯级水电站为例
A coupling model of load adjustment for cascade hydropower stations based on inflow uncertainty: A case study of Jinping-guandi cascade hydropower stations
摘要
Abstract
To solve the deviation caused by inflow uncertainty between the actual operation requirements of cascade hydropower stations and its original power generation schedule,on the one hand,an early warning mechanism for safe operation,which combines risk management connotation and hydropower stations operation rules,is proposed to meet the goal of establishing continuous monitoring and evaluation on the schedule.On the other hand,a new coupling model of load adjustment for cascade hydropower stations is developed based on error analysis method and reservoir operation theory.By setting the early warning results as time control nodes,a nested application mode for the mechanism and the model is constructed.Meanwhile,an algorithm considering security constraints in the power grid is introduced herein.Consider Jinping-guandi cascade hydropower stations as an example.The modeling results show that the proposed model can effectively solve the problem that the power plant is forced to reduce output or release surplus water due to inflow uncertainty.The developed load adjustment scheme can also meet the requirements of hydropower stations operation and ensure safety and stability of power grids.Hence,the rationality of the model is verified by the modeling results.关键词
