基于时序运行模拟的水火风光储互补系统电源优化配置OA北大核心CSTPCD
Optimal capacity configuration for hydroelectric-thermal-wind-photovoltaic-storage multi-energy complementary system based on sequential power generation simulations
系统时序运行模拟是水火风光储互补系统电源规模优化配置的关键环节.对于水火风光储多能互补系统8760逐小时运行模拟,按照小时尺度构建的模型规模很大,直接求解困难.本文提出按时间尺度逐层分解、递进优化的高效求解算法,精确模拟系统全年逐小时调度运行过程.在此基础上,构建双层规划模型对由风电、光伏、水电、火电、抽水蓄能、梯级水电站混合式抽水蓄能和电化学储能等电源组成的并网多能互补系统的电源容量进行优化配置.将模型应用在青海省电网系统中,对风电、光伏、抽水蓄能电站和基于水电站的可逆机组容量进行优化,得到电源最佳配置方案.
Sequential power generation simulations play a critical role in the capacity configuration of hydroelectric-thermal-wind-photovoltaic-storage multi-energy complementary systems.In practice,8760-hour system operation are hard to simulate directly using an optimization model because of its large scale.In this paper,a new time-scale decomposing technique is developed to solve this problem and realize the accurate simulations of 8760-hour system operation.Based on this,a two-stage optimization model is constructed for capacity configuration of a grid-connected multi-energy complementary system that comprises thermal power,hydropower,wind,photovoltaic,pumped-storage,and electrochemical energy storage.This new model was applied to the Qinghai power grid and achieved an optimized configuration of the system's capacity of wind,photovoltaic,and pumped-storage.
