Abstract

The shift toward decentralized and renewable energy sources has introduced significant challenges to traditional power systems, necessitating innovative market designs. Local energy markets present a viable solution for integrating distributed energy resources such as photovoltaic systems, electric vehicles, and heat pumps. This study investigates the techno-economic implications of local energy markets compared to conventional market designs, focusing on their impact on average energy prices and operational peak power. Through comprehensive simulations across various grid topologies with varying penetration levels of the distributed energy resources, totaling 400 simulation setups, we demonstrate that local energy markets can enhance economic efficiency and grid stability with 99% of the scenarios boasting lower average energy prices and 80% lower operational peak power levels. The findings suggest that local energy markets can play a role in the future energy system, provided that additional infrastructure, management costs, and bureaucratic complexity are kept to a minimum.

评估不同电网拓扑和产消份额的lem的技术经济效益

向分散式和可再生能源的转变给传统电力系统带来了重大挑战，需要创新的市场设计。当地能源市场为整合分布式能源（如光伏系统、电动汽车和热泵）提供了一个可行的解决方案。本研究调查了与传统市场设计相比，当地能源市场的技术经济含义，重点关注其对平均能源价格和运行峰值功率的影响。通过对分布式能源渗透水平不同的各种电网拓扑的综合模拟，总共400个模拟设置，我们证明了当地能源市场可以提高经济效率和电网稳定性，其中99%的情景具有较低的平均能源价格和80%的运行峰值功率水平。研究结果表明，只要额外的基础设施、管理成本和官僚复杂性保持在最低水平，地方能源市场可以在未来的能源系统中发挥作用。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
