摘要

在中国北方地区省级电-热综合能源系统中，随着风光新能源占比的不断提升，将调度周期内整体过剩的新能源有序存储在电、热储能中用于后续调度周期，成为越来越常见的目前调度场景。现有基于弃电惩罚的调度模型在应用于多能源系统调度时，因存在多解而无法引导新能源弃电在异质储能中有序、高效存储。为此，提出了将电、热储能的日末蓄能量根据后续日利用价值折算为等效成本，并纳入调度模型目标函数予以扣减的策略；通过对电、热储能在非弃电与弃电场景下6种运行情况的理论分析，确定了电、热储能蓄能量等效成本折算系数的合理取值范围，实现了对调度过程中电、热储能的有序引导。以中国北方某省级电-热综合能源系统为参考进行算例分析，验证了所提调度模型的有效性与优越性。

Abstract

In the provincial electric-thermal integrated energy systems in Northern China

with the continuously growing penetration of wind-solar renewable energy

orderly storing the overall surplus renewable energy within a scheduling cycle into electric and thermal energy storage devices for subsequent scheduling cycles has become an increasingly common day-ahead scheduling scenario. Aiming at the problem that existing scheduling models based on curtailment penalty suffer from multiple solutions when applied to multi-energy system scheduling

which fails to guide the orderly and efficient storage of curtailed renewable energy among heterogeneous energy storages

this paper proposes a strategy that converts the end-of-day stored energy of electric and thermal energy storage into equivalent costs according to their utilization value in subsequent days

and deducts such equivalent costs in the objective function of the scheduling model. Through theoretical analysis of six operating conditions of electric-thermal energy storage in non-curtailment and curtailment scenarios

the reasonable value range of conversion coefficients for the equivalent cost of stored energy in electric and thermal energy storage is determined

and the orderly guidance for electric-thermal energy storage during scheduling is realized. Case studies are conducted based on a provincial electric-thermal integrated energy system in Northern China to verify the effectiveness and superiority of the proposed scheduling model.
