摘要

随着高比例新能源的渗透，发电侧调节能力大幅减弱，仅依靠常规可控电源的调控方式将产生大量弃风弃光。为此，提出以“可调”满足“不可调”的电力平衡方式，协调大规模的需求侧资源参与需求响应（DR）。首先，分析了当前各类DR机制在大规模DR中存在的局限性，特别是基线负荷面临的诸多问题；接着，提出了负荷准线的概念、模型、响应效果评价指标以及基于准线的DR实施方案；将可以有效平抑系统内不可控波动的理想负荷曲线形状定义为负荷准线，各用户在激励作用下，根据自身偏好自主地调整自身用电方式使其负荷形状趋近准线，从而实现可调资源与不可调资源的实时平衡。相比现有的DR机制，负荷准线简单易行，适用于大规模推广，从根本上提升系统调节能力，极大促进新能源的消纳。基于构建的测试系统，算例分析表明所提机制可有效降低高比例新能源电力系统的弃风弃光量。

Abstract

With the penetration of high-proportion renewable energy

the regulation capability of generation resources reduces significantly

and the curtailment of wind power and photovoltaic are huge if only relying on conventional controllable power sources. To solve the problems above

this paper proposes a power balancing scheme by regulating controllable resources to satisfy the uncontrollable resources， and coordinating large-scale demand-side resources in demand response (DR) mechanism. Firstly

the limitations of diverse DR mechanisms in large-scale DR are analyzed

especially several problems of customer baseline load (CBL). Secondly

the definition

model and response evaluation indices of the customer directrix load (CDL) are proposed together with the CDL-based DR implementation scheme. CDL is defined as a desired load profile that could effectively offset the uncontrollable fluctuations in power system. DR customers are incentivized to individually reshape their power usage ways to approach CDL considering their preferences

and the controllable resources will achieve real-time power balance with uncontrollable resources. Compared with the current DR mechanisms

CDL is more feasible to be deployed and more suitable for large-scale promotion

which fundamentally enhances the system regulation capability and greatly promotes the consumption of renewable energy. Based on the built test system

the results of the case study indicate that the proposed mechanism can significantly reduce the curtailment of wind power and photovoltaic.
