摘要(Abstract):

为了实现碳中和目标下的能源转型,以风电、光伏为代表的新能源将成为未来电力系统的主要电源。然而,高比例可再生能源的接入在带来高不确定性的同时降低了系统惯性,传统电力系统的调节资源无法满足未来电力系统的调度需求,需要从“源随荷动”传统模式向“源荷互动”协同模式转变。为此,对面向电力系统调度需求的负荷资源调控技术进行了综述。从电网运行调度的角度阐述了将可控负荷纳入电网运行调度的必要性,并从调度响应时间、调度响应方式、用户用电特点、能量传递方向、聚合商平台特点等5个方面对可控负荷进行分类。针对可控负荷接入对电力系统调度的影响,分别从建模技术、调度形式及调度架构方面进行分析。结合我国当前电力系统发展情况,提出了可控负荷资源参与电网运行调度的建议与展望。
In order to realize the energy transformation under the goal of carbon neutrality,new energy represented by wind power and photovoltaic power will serve as the main power supply for the future power system. However,the access of high-proportion renewable energy brings about high uncertainty and undermines system inertia,so much so that the scheduling resources of the traditional power system can no longer meet the scheduling demand of the future power system. Hence,a transformation from“the source changes with load”to“the interaction between source and load”. Therefore,this paper summarizes the load resource scheduling methods geared for power system scheduling. Firstly,from the perspective of power grid operation scheduling,the necessity of bringing controllable load into power grid operation scheduling is expounded,and controllable load is classified from five aspects:dispatching response time,dispatching response mode,users' power consumption characteristics,energy transfer direction and load aggregator platform. Then,the influence of controllable load access on power system scheduling is analyzed from the aspects of modeling technology,scheduling form and scheduling architecture. Finally,combined with the current development of power system in China,the suggestion and prospect of controllable load resources participating in power grid operation scheduling are put forward.
