电价是私人消费者采用分布式能源(DERs)的主要驱动因素。反过来,从长远来看,DERs是能源获取可靠性的主要组成部分。在一个既在仪表后又在仪表前产生能源的范例中,定义可靠性指数是正在进行的关于公用事业和系统运营商未来角色的讨论的一部分,其中涉及许多监管问题。本文通过分析费率设计对配电长期可靠性指标的影响,为这一讨论做出贡献。提出了一种量化这种影响的方法,并提出了一个涉及光伏(PV)和存储技术在加利福尼亚州采用的案例研究。几个数值模拟说明了电价是如何通过改变调度和采用DERs来影响电网可靠性的。我们进一步证明,从公用事业和消费者的角度来看,费率设计对可靠性的影响可能非常不同。我们的模型证实了可再生能源投资与电网可靠性之间的正相关关系,并为政策制定者提供了一个额外的工具,以提高电网的长期可靠性。
Electricity rates are a main driver for adoption of Distributed Energy Resources (DERs) by private consumers. In turn, DERs are a major component of the reliability of energy access in the long run. Defining reliability indices in a paradigm where energy is generated both behind and in front of the meter is part of an ongoing discussion about the future role of utilities and system operators with many regulatory implications. This paper contributes to that discussion by analyzing the effect of rate design on the long term reliability indices of power distribution. A methodology to quantify this effect is proposed and a case study involving photovoltaic (PV) and storage technology adoption in California is presented. Several numerical simulations illustrate how electricity rates affect the grid reliability by altering dispatch and adoption of the DERs. We further document that the impact of rate design on reliability can be very different from the perspective of the utility versus that of the consumers. Our model affirms the positive connection between investments in DERs and the grid reliability and provides an additional tool to policy-makers for improving the reliability of the grid in the long term.
