摘要:

以用户侧储能的经济和技术特征为基础,考虑用户侧储能的内部收益和外部收益增量,提出了用户侧储能适应值指标,并作为优化目标;为了验证适应值指标的一般性,选取负荷聚集商和虚拟电厂新技术作为研究对象进行分析。以实时电价能量市场为背景,选取某工业用户进行仿真,结果表明,适应值指标可以量化用户侧储能的适应能力;虚拟电厂中存在用户侧储能的需求互补对象风电商,提升了用户侧储能的适应性。

Abstract:

Based on the economic and technical characteristics of user-side energy storage,this paper considers the internal and external revenue increments of user-side energy storage,and proposes user-side energy storage fitness value indicators,which are used as optimization goals.To verify the generality of the value index,the load aggregator and the new technology of the virtual power plant are selected as the research objects for detailed characterization.Taking a real-time electricity price energy market as the background,a certain industrial user was selected for simulation.The results show that the fitness index can quantify the adaptive capacity of the user-side energy storage; revealing that the user-side energy storage only depends on the peak and valley reduction of basic electricity and electricity costs.It is basically not profitable,but there is a wind power supplier that is a complementary object of user-side energy storage demand in the virtual power plant,which improves the adaptability of user-side energy storage.

Key words: user-side energy storage, virtual power plant, load aggregator, wind energy dissipation, adaptability
