抽水蓄能灰启动下冷热电互补综合能源系统优化调度
Optimization Scheduling of Cold-Heat-Electricity Integrated Energy System Under Pumped Storage Gray Start
摘要
Abstract
[Objectives]Pumped storage units have gray start potential.Integrating this capability with the multi-energy complementary advantages of an integrated energy system(IES)makes it suitable for system recovery under extreme events.To investigate the post-disaster recovery mechanism of IES,this paper proposes an optimization scheduling model for a cold-heat-electricity integrated energy system(CHEIES)under pumped storage gray start.[Methods]First,stochastic scenario optimization is employed to address the uncertainties in wind,solar,cold,and thermal power.Latin hypercube sampling is used to generate a large number of random wind-solar-cold-heat scenarios,and a probability distance-based rapid reduction method is applied to reduce the number of scenarios.Then,for CHEIES under gray start,pumped storage serves as the gray start power source to provide startup power for the combined heat and power unit.A single-objective optimization scheduling model is established with gray start benefit as the core consideration,incorporating cold-heat-electricity power balance constraints to ensure the stable operation of IES under various load conditions.Finally,simulations are conducted to solve the model,and optimization scheduling strategies and economic benefits under different operation schemes are analyzed.[Results]CHEIES with pumped storage ash start-up shows high flexibility and operation efficiency in response to extreme natural disasters.Compared with the scheme without pumped storage ash start-up,the system operation cost is reduced by 12.14%.[Conclusions]The proposed method fully explores the reliability,economic efficiency,and flexibility of CHEIES under emergency conditions,providing strategic support for the rapid recovery of IES after extreme events.关键词
