In order to meet ever-stricter climate targets and achieve the eventual decarbonization of the energy supply of German industrial metropolises, the focus is on gradually phasing out nuclear power, then coal and gas combined with the increased use of renewable energy sources and employing hydrogen as a clean energy carrier. While complete electrification of the energy supply of households and the transportation sector may be the ultimate goal, a transitional phase is necessary as such massive as well as rapid expansion of the electrical distribution grid is infeasible. Additionally, German industries have expressed their plans to use hydrogen as their primary strategy in meeting carbon targets. This poses challenges to the existing electrical, gas, and heating distribution grids. It becomes necessary to integrate the planning and developing procedures for these grids to maximize efficiencies and guarantee security of supply during the transition. The aim of this paper is thus to highlight those challenges and present novel concepts for the integrated planning of the three grids as one multi-energy grid.

多能源电网综合规划：概念与挑战

为了满足日益严格的气候目标并实现德国工业大都市能源供应的最终脱碳，重点是逐步淘汰核能，然后是煤炭和天然气，同时增加可再生能源的使用，并以氢作为燃料。清洁能源载体。虽然家庭和交通部门能源供应的完全电气化可能是最终目标，但过渡阶段是必要的，因为配电网的大规模和快速扩张是不可行的。此外，德国工业界已表示计划将氢作为实现碳排放目标的主要战略。这对现有的电力、天然气和供热分配网络提出了挑战。有必要整合这些电网的规划和开发程序，以最大限度地提高效率并确保过渡期间的供应安全。因此，本文的目的是强调这些挑战，并提出将三个电网整合为一个多能源电网的新概念。
