In realizing seamless mass adoption of electric vehicles (EVs), the government plays a vital role by framing and implementing various EV related policies. These policies, if framed adequately, play a key role in achieving electrification of transportation in States. The literature review suggests that there is a pressing need to develop a unified method to analyze the EV policy of a State and determine its effectiveness as well as key interventions to strengthen EV policy. Therefore, to determine the quality and the effectiveness of EV policies, a quantitative analysis of EV policies by using the Hamming distance and the L1 norm (Manhattan distance) has been proposed in this paper. The policies are analyzed based on essential interventions to promote and strengthen electric mobility. This paper proposes an L1 norm-based EV policy analysis that assigns a remoteness score to indicate the status of the existing EV policy and its implementation when compared to the ideal EV policy. The paper proposes an approach that is based on three methods to improve the remoteness score: cost of intervention implementation, benefit of the intervention to the EV ecosystem, and the number of move/steps that are required to reduce the remoteness score. The proposed approach as applied to various Indian State EV policies has identified the States whose EV policies have lower remoteness score, thereby highlighting the States having relatively better EV policies. The analysis of these methods for optimal intervention selection when implemented for various State EV policies shows that the intervention implementation cost-based method is the most economical one. This paper formulates a linear optimization problem with the objective of intervention-implementation cost minimization to develop an economical roadmap to reduce the remoteness score. Recommendations for EV policy makers and stakeholders using an optimization based quantitative analysis of EV policies in India are also presented in this paper.
为了实现电动汽车的无缝普及,政府通过制定和实施各种电动汽车相关政策发挥着至关重要的作用。这些政策如果框架适当,将在各国实现运输电气化方面发挥关键作用。文献综述表明,迫切需要建立一种统一的方法来分析国家的电动汽车政策,确定其有效性,以及加强电动汽车政策的关键干预措施。因此,为了确定电动汽车政策的质量和有效性,本文提出了使用汉明距离和L1范数(曼哈顿距离)对电动汽车政策进行定量分析的方法。根据促进和加强电动交通的基本干预措施,分析了政策。本文提出了一种基于L1规范的电动汽车策略分析,该分析分配了一个远程分数,以表明现有电动汽车策略的状态及其与理想电动汽车策略的实施情况。本文提出了一种基于三种方法来提高远程评分的方法:实施干预的成本,干预对电动汽车生态系统的好处,以及降低远程评分所需的移动/步数。该方法应用于印度各邦电动汽车政策,确定了电动汽车政策偏远程度较低的邦,从而突出了电动汽车政策相对较好的邦。对各种国家电动汽车政策实施干预的最优选择方法进行了分析,结果表明基于成本的干预实施方法是最经济的干预实施方法。本文以干预实施成本最小化为目标,建立了一个线性优化问题,以制定降低远程评分的经济路线图。本文还对印度电动汽车政策进行了基于优化的定量分析,为电动汽车政策制定者和利益相关者提出了建议。

In the modern power grids, the energy market has been developing rapidly, along with the growth of multi-energy combined tradings. Consequently, studies of interactions behaviours between various agents (e.g., game theory) in the energy market becomes prevalent to properly analyze and regulate the energy market. However, most of existing works have been focusing on the equilibria analysis of static games, and little works have been done regarding designing feedback control on dynamic games, particularly when the system dynamics changes under disturbances. In this paper, a novel game-based feedback control design method is proposed using semi-tensor product (STP) of matrices. The state-space equations of the dynamic game is firstly derived considering the decision logics and interactive correlations between various agents in the energy market. Then, a novel set of mathematical derivations has been proposed to implement control on some agents such that the price of the energy market can be regulated despite of randomly changing states and potential disturbances to the decision making. Finally, a simulated energy market using the proposed STP game-based control is demonstrated, where the results are discussed and the effectiveness of the proposed method is validated.
在现代电网中,能源市场发展迅速,多种能源并网交易日益增多。因此,研究能源市场中各主体之间的相互作用行为(如博弈论)成为正确分析和规范能源市场的主流。然而,现有的研究大多集中在静态博弈的均衡分析上,而对于动态博弈的反馈控制设计,特别是当系统动力学在扰动下发生变化时,研究较少。本文利用矩阵的半张量积,提出了一种新的基于博弈的反馈控制设计方法。首先考虑能源市场中各主体之间的决策逻辑和交互关系,导出了动态博弈的状态空间方程。然后,提出了一组新的数学推导来实现对某些代理的控制,使得能源市场的价格可以在随机变化的状态和潜在干扰下进行调节。最后,利用所提出的基于STP博弈控制的模拟能源市场进行了演示,并对结果进行了讨论,验证了所提出方法的有效性。

Flexible Ramping Product Procurement in Day-Ahead Markets 日前市场中的灵活斜坡产品采购

Flexible ramping products (FRPs) emerge as a promising instrument for addressing steep and uncertain ramping needs through market mechanisms. Initial implementations of FRPs in North American electricity markets, however, revealed several shortcomings in existing FRP designs. In many instances, FRP prices failed to signal the true value of ramping capacity, most notably evident in zero FRP prices observed in a myriad of periods during which the system was in acute need for rampable capacity. These periods were marked by scheduled but undeliverable FRPs, often calling for operator out-of-market actions. On top of that, the methods used for procuring FRPs have been primarily rule-based, lacking explicit economic underpinnings. In this paper, we put forth an alternative framework for FRP procurement, which seeks to set FRP requirements and schedule FRP awards such that the expected system operation cost is minimized. Using real-world data from U.S. ISOs, we showcase the relative merits of the framework in (i) reducing the total system operation cost, (ii) improving price formation, (iii) enhancing the the deliverability of FRP awards, and (iv) reducing the need for out-of-market actions.
灵活的斜坡产品(frp)是通过市场机制解决陡峭和不确定的斜坡需求的一种有前途的工具。然而,FRP在北美电力市场的初步实施暴露了现有FRP设计的几个缺点。在许多情况下,玻璃钢价格未能反映产能增加的真实价值,最明显的是,在系统迫切需要产能增加的无数个时期,玻璃钢价格为零。这段时间的特点是计划好的但无法交付的frp,通常要求运营商采取市场外行动。最重要的是,用于采购frp的方法主要基于规则,缺乏明确的经济基础。在本文中,我们提出了玻璃钢采购的替代框架,该框架旨在设定玻璃钢要求并安排玻璃钢奖励,从而使预期的系统运行成本最小化。使用来自美国iso的真实数据,我们展示了该框架在以下方面的相对优点:(i)降低系统总运营成本,(ii)改善价格形成,(iii)提高FRP奖励的可交付性,以及(iv)减少对市场外行动的需求。

The urgent need for decarbonization in the energy sector has led to an increased emphasis on the integration of renewable energy sources, such as wind and solar, into power grids. While these resources offer significant environmental benefits, they also introduce challenges related to intermittency and variability. Long-duration energy storage (LDES) technologies have emerged as a very promising solution to address these challenges by storing excess energy during periods of high generation and delivering it when demand is high or renewable resources are scarce for a sustained amount of time. This paper introduces a novel methodology for estimating the boundary technology cost of LDES systems for economic viability in decarbonized energy systems. Our methodology is applied to estimate the boundary costs in 2050 for the state of California to achieve full retirement of gas power plants. California's ambitious decarbonization goals and transition to a renewable energy-based power system present an ideal context for examining the role of LDES. The results also offer insights into the needed capacity expansion planning and the operational contribution of LDES in the California's energy landscape, taking into account the unique energy demand profiles and renewable resource availability of the region. Our findings are intended to provide complementary information to guide decision-makers, energy planners, and any other stakeholders in making informed choices about LDES investment in the context of a decarbonized energy future.
由于能源部门迫切需要脱碳,因此更加强调将风能和太阳能等可再生能源纳入电网。虽然这些资源提供了显著的环境效益,但它们也带来了与间歇性和可变性相关的挑战。长期储能(LDES)技术已经成为解决这些挑战的一种非常有前途的解决方案,它可以在高发电量期间存储多余的能量,并在需求高或可再生资源持续稀缺的情况下输送能量。本文介绍了一种估算LDES系统在脱碳能源系统中经济可行性的边界技术成本的新方法。我们的方法被应用于估计加州在2050年实现天然气发电厂完全退役的边界成本。加州雄心勃勃的脱碳目标和向以可再生能源为基础的电力系统的过渡为研究LDES的作用提供了理想的环境。考虑到该地区独特的能源需求概况和可再生资源的可用性,研究结果还为加州能源景观所需的容量扩展规划和LDES的运营贡献提供了见解。我们的研究结果旨在提供补充信息,以指导决策者、能源规划者和任何其他利益相关者在脱碳能源未来的背景下做出关于LDES投资的明智选择。

An Affordable Sophisticated Frequency Control Ancillary Services for Australian National Electricity Market System Considering Industry and Infrastructure Challenges 考虑到工业和基础设施挑战,澳大利亚国家电力市场系统可负担得起的复杂频率控制辅助服务

This industry-oriented paper proposes a novel sophisticated frequency control and its ancillary services framework for the Australian National Electricity Market (NEM) power system considering the special design of its current automatic generation control system, which does not involve interconnectors between different power regions, resulting in technical challenges for both stability and security of the system. The proposed new method converts the NEM centralized frequency control system to a fully decentralized one with virtual consideration of interconnectors' power, thus the stability and security would be improved, and high fluctuations in interchanged power would be smoothed without extra costs of infrastructure and procurement of frequency control ancillary reserves (FCASs). The novel idea is to model the interconnectors' power deviation as unknown input to the operator in each power region, like load disturbances and renewable power variations, using dynamic observation techniques, for enabling the proposed method capabilities. The method is theoretically verified that it can enhance stability and security and stabilize both local frequencies and power exchanges. The experiment results confirm the capability of the proposed method for the NEM system and its superiority over the existing adopted approaches in industries.
考虑到澳大利亚国家电力市场(NEM)电力系统当前自动发电控制系统的特殊设计,该系统不涉及不同电力区域之间的互连,导致系统稳定性和安全性面临技术挑战,本文提出了一种新的复杂频率控制及其辅助服务框架。该方法将NEM集中频率控制系统转换为虚拟考虑互联电源功率的完全分散频率控制系统,提高了系统的稳定性和安全性,平滑了交换电源的高波动,且不需要额外的基础设施和频率控制辅助储备(fass)的采购成本。新颖的想法是将互连器的功率偏差建模为每个功率区域的未知输入,如负载干扰和可再生能源变化,使用动态观察技术,以实现所提出的方法功能。理论验证表明,该方法可以提高稳定性和安全性,同时稳定本地频率和功率交换。实验结果证实了所提出的方法对NEM系统的能力,以及它比现有工业中采用的方法的优越性。

A Comparison of Three Methods for ISO Pricing 三种ISO定价方法的比较

In the presence of non-convex constraints, RTOs/ISOs need to introduce side payments to ensure non-confiscatory pricing. The side payment is not uniform and is non-transparent. To address this concern, Convex Hull Price (CHP) is developed to minimize uplift. However, the side payment defined in the tariff of RTOs/ISOs usually only covers make-whole-payments (MWP), not consistent with the uplift defined in CHP. This paper introduces a unified solution approach that can achieve uniform prices under different market rules. Previous research has shown that by developing a convex hull and convex envelope formulation for individual resources, a CHP model that minimizes uplift can be solved by linear programming (LP) using relaxation of the binary terms of the security constrained unit commitment (SCUC) problem. This paper proves that by adjusting resource upper bounds based on the SCUC solution, the one-pass LP relaxation of the SCUC problem can also be used to derive average incremental price (AIC), eliminating MWP. Case studies using both small systems and the MISO full day ahead models are presented to compare MWP, uplift and generator profit under LMP, CHP and AIC.
在存在非凸约束的情况下,rto / iso需要引入侧支付来确保非没收定价。附加支付不统一,不透明。为了解决这个问题,开发了凸壳价格(CHP)来最大限度地减少隆起。然而,在rto / iso的收费标准中定义的附加付款通常只包括全额付款(MWP),与CHP中定义的提升不一致。本文介绍了在不同市场规则下实现统一价格的统一求解方法。先前的研究表明,通过开发单个资源的凸壳和凸包络公式,可以通过线性规划(LP)利用安全约束单元承诺(SCUC)问题的二进制项的松弛来求解最小化凸起的热电联产模型。在此基础上,通过调整资源上界,证明了scucc问题的单次LP松弛也可用于推导平均增量价格(AIC),从而消除了MWP。采用小型系统和MISO全天提前模型进行了案例研究,比较了LMP、CHP和AIC下的MWP、隆升和发电机利润。

This letter proposes a market-clearing-based locational marginal carbon emission (LMCE) metric to assess the marginal carbon emission effect of nodal load demand. Unlike the prevalent carbon emission flow (CEF) method that relies on a hypothetical power-flow tracking process, the proposed LMCE metric depends on a novel sensitivity analysis of market-clearing results, capable of revealing both energy-dependent and network-dependent impacts on emissions. Additionally, we introduce a locational average carbon emission (LACE) metric, derived from LMCE, to effectively measure the general emission effect. It offers insights into demand-side carbon emission effects, such as a negative LMCE and LACE indicating emission reduction even as load increases. It can also prevent excessive demand-side emission allocations. Overall, the proposed method provides a clear perspective for the ongoing decarbonization policies.
本文提出了一个基于市场清算的区位边际碳排放(LMCE)指标来评估节点负荷需求的边际碳排放效应。与普遍的碳排放流(CEF)方法不同,该方法依赖于假设的功率流跟踪过程,而拟议的LMCE指标依赖于对市场清算结果的新颖敏感性分析,能够揭示能源依赖性和网络依赖性对排放的影响。此外,我们引入了从LMCE衍生而来的区位平均碳排放(LACE)指标,以有效衡量总体排放效应。它提供了对需求侧碳排放影响的见解,例如负的LMCE和LACE表明即使负荷增加也会减少排放量。它还可以防止过度的需求侧排放分配。总的来说,所提出的方法为正在进行的脱碳政策提供了一个清晰的视角。
