摘要(Abstract)：

新型电力系统建设背景下，关注虚拟电厂参与电网调控运行的需求响应管理策略具有重要意义，但目前多数研究集中于单一负荷资源的需求响应潜力分析，未将区域中所有用户考虑进来。对此，提出了适用于所有用户的负荷时间、价格弹性的评估方法，发现负荷率、时间弹性系数、价格交叉弹性系数在评估中发挥较大作用，而价格自弹性系数则影响不大；采用负荷弹性系数辨识用户在电力价格或激励作用下用电负荷时间上的灵活性与可控性，并以浙江金华典型电力用户为例展开测算，验证了此需求响应潜力评估方法具有一定的实用价值。
In the context of constructing a new-type power system, the demand response management strategy focusing on virtual power plants participating in power grid scheduling and operation is of great significance. However, most studies now focus on the demand response potential analysis of single load resources and do not take account of all users in the region. Therefore, this paper proposes an evaluation method of load time and price elasticity applicable to all users. It is found that load rate, time elasticity coefficient, and price cross-elasticity coefficient play a greater role than the price self-elasticity coefficient in the assessment. The load elasticity coefficient is used to identify the flexibility and controllability of customers' electricity load time under the effect of electricity price or incentive. Moreover, typical electricity customers in Jinhua are used for calculation, and the practical value of the demand response potential assessment method is verified.
