摘要

我们的研究从网络的角度对电网进行了创新性分析，揭示了德克萨斯州批发电力市场的关键方面。通过采用电力系统工程模型，我们构建了输电网络表示，为经济学文献做出了新的贡献。通过对网络矩阵的分析，我们深入研究了德克萨斯州电网的特点，特别关注竞争性可再生能源区（CREZ）项目带来的结构变化及其对节点价格的影响。经验分析提供了额外的证据，表明忽视输电网的变化会导致对各种系数的估计存在偏差。这包括空间相关性系数，以及与控制变量（如风力生产和负荷）相关的系数。这些实证结果强调了网络分析在电网研究中的意义和独特价值。

Wholesale price dynamics in the evolving Texas power grid

Our study conducts an innovative analysis of the power grid from a network perspective, shedding light on crucial aspects of the wholesale electricity market in Texas. By employing a power system engineering model, we construct a transmission network representation, presenting a novel contribution to the economics literature. Through our analysis of the network matrix, we delve into the characteristics of the Texas power grid, specifically focusing on the structural changes resulting from the Competitive Renewable Energy Zone (CREZ) project and their impacts on nodal prices. The empirical analysis provides additional evidence that ignoring changes in the transmission grid leads to biased estimates of various coefficients. This includes the spatial dependence coefficient, as well as the coefficients associated with control variables such as wind production and load. These empirical findings underscore the significance and distinctive value of network analysis in studying power grids.

期刊介绍： The Electricity Journal is the leading journal in electric power policy. The journal deals primarily with fuel diversity and the energy mix needed for optimal energy market performance, and therefore covers the full spectrum of energy, from coal, nuclear, natural gas and oil, to renewable energy sources including hydro, solar, geothermal and wind power. Recently, the journal has been publishing in emerging areas including energy storage, microgrid strategies, dynamic pricing, cyber security, climate change, cap and trade, distributed generation, net metering, transmission and generation market dynamics. The Electricity Journal aims to bring together the most thoughtful and influential thinkers globally from across industry, practitioners, government, policymakers and academia. The Editorial Advisory Board is comprised of electric industry thought leaders who have served as regulators, consultants, litigators, and market advocates. Their collective experience helps ensure that the most relevant and thought-provoking issues are presented to our readers, and helps navigate the emerging shape and design of the electricity/energy industry.
