Abstract Nowadays, the attainment of flexibility in different loads for different electricity customers is an interesting topic. The assessment of flexibility is important because of the ultimate benefits to handle challenges for both electricity customers and utilities. At first, different loads that have significant contribution in energy consumption and may be potential candidates for the extraction of demand flexibility are discussed in this paper. Secondly, different descriptions of demand side flexibility and its assessment manipulation on individual and aggregate loads are explored. After investigation of different techniques some innovative definitions of flexibility indices are surveyed for numerical flexibility assessment. The information about the flexibility potential can lead to initiate different Demand Side Management (DSM) techniques that is helpful to solve electrical power systems key issues. Keeping in view this aspect, different DSM techniques for Demand Response (DR) programs are also reviewed in this paper.

不同能源部门的电力需求及其灵活性

摘要 如今，为不同的电力客户实现不同负载的灵活性是一个有趣的话题。灵活性的评估很重要，因为它可以为电力客户和公用事业单位解决挑战。首先，本文讨论了对能源消耗有显着贡献并且可能是提取需求灵活性的潜在候选者的不同负载。其次，探索了需求侧灵活性的不同描述及其对单个和总负载的评估操作。在研究了不同的技术后，对柔性指数的一些创新定义进行了调查，以进行数值柔性评估。有关灵活性潜力的信息可以导致启动不同的需求侧管理 (DSM) 技术，这有助于解决电力系统的关键问题。考虑到这一点，本文还回顾了用于需求响应 (DR) 计划的不同 DSM 技术。
